Could Not Load Dynamic Library Libcublas.So.10 Dlerror: Libcublas.So.10: Cannot Open Shared Object File

To understand more about this issue, it’s important to note that both the “Could Not Load Dynamic Library libcublas.so.10” and “Dlerror: libcublas.so.10: Cannot Open Shared Object File” errors imply that there’s an issue with the CUDA setup in your system. Specifically, the system is not able to load the shared dynamic library file libcublas.so.10.

This problem could be due to several reasons such as the targeted shared library file doesn’t exist on the given location or the current user does not have sufficient permissions to access it. Additionally, the installed CUDA version might not match with the referenced one causing the issue.

To fix this issue:

– Reinstall the library by using the appropriate package manager. For Debian derivatives like Ubuntu, this would be dpkg or apt. For Red Hat based systems, you should use yum or dnf.

apt-get install libcublas10

– Manually download the required shared library file and put it in a directory where the operating system can find it, typically /usr/lib or /usr/local/lib are good candidates. Ensure that you update the ldconfig cache after doing so.

– Add a symbolic link to libcublas.so.10 from a version of the libcublas library that exists in your system. This might not always work, especially if the two versions of libcublas library are not compatible.

Additionally, It may also require Environment variable maintenance for correct path resolution. The LD_LIBRARY_PATH variable ensures that executable files are properly linked to their libraries upon execution.

export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

I must suggest that these solutions should be tailored as per the specific system environment and requirements. Always back up important data before making any significant changes to your system. Mistakes or out-of-date instructions can occasionally result in unwanted behavior, even if followed precisely.

The libcublas.so.10 error commonly found in many programming fields, particularly when working with CUDA software, is quite a common one for programmers and script creators around the world. The basis of this error lies within a problematic situation where your system is unable to load a dynamic library. Specifically, it cannot load the dynamic library:

libcublas.so.10

.

Now, fundamentally, the .so (.dll for windows users) files are a reference to libraries that contain code and data that can be used by multiple programs simultaneously. For instance,

libcublas.so.10

is part of the NVIDIA CUDA Runtime and is critical for programs leveraging CUDA functionalities.

So, with this particular error “Could Not Load Dynamic Library”, there could be multiple causes behind it:

* It’s possible that the software is looking for the library at an incorrect location.
* A conflicting version might be installed on your machine. You may have a newer or older version of the library that doesn’t match up with what the software requires.
* It could also mean that the required library, in this case, libcublas.so.10 is missing from your machine.

To resolve this issue:

– First, you need to check whether the library exists on your system. You can use find command:

find /usr -name 'libcublas.so.10'

If this returns an empty response, it means the library does not exist on your system, and you need to install it.

– If the library exists, then ensure that the location of this library is in your system’s PATH.

You should open your bashrc file using any text-editing tool and add the following lines:

export PATH=/usr/local/cuda-10.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64\
                             ${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

Here, replace “/usr/local/cuda-10.0” with the path where your CUDA toolkit resides.

– In case a wrong version of the library is causing the error, verify the CUDA version that you have installed. Various versions of CUDA require different versions of the libcublas library. If you’re running CUDA 10.0, for example, but only have libcublas for CUDA 11.0, it might lead to compatibility issues.

Finally, save your changes and source your bashrc file (

source ~/.bashrc

) to reflect the newly made changes in the current session. Run your program/script again to check if the issue has been resolved.

It is important to note that handling such dynamic libraries demands attention since they form critical components for many applications to function properly. Knowing how to navigate through these issues saves much time and accelerates application development.

For optimal solutions, always refer to the official Nvidia guidelines [1] and credible online platforms for developers.

Don’t forget, even professionals like us encounter these issues frequently, so you’re never alone in tackling them! Keep experimenting different fixes until you hit the right solution spot!

There could be multiple reasons causing failure in loading the

libcublas.so.10

dynamic library. They can range from an incorrect setup on your machine, missing installation instructions or even outdated versions of source libraries.

The main causes behind the problem are generally:

1. Environtment Variables Are Not Set Properly

– The operating system’s environment variables might not have been set correctly. These variables are important for the correct functioning of the program. They tell your operating system where to find certain files and directories.

– You need to ensure you add the appropriate CUDA paths to your LD_LIBRARY_PATH. If you’ve installed CUDA in a non-default location, then this step is critical otherwise your system won’t know where to look for these important library files.

An example snippet of how to do this would be:

export PATH=/usr/local/cuda-10.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64\${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

2. Incompatible or Incorrect Library Versions

– It also might possibly be due to wrong or incompatible versions of software libraries in your system. Check the version of your CUDA Toolkit and cuDNN.

– Depending on the TensorFlow version there might be specific version dependencies with CUDA and cuDNN as well. For instance, some TensorFlow releases only work with CUDA 9.0, which doesn’t include libcublas.so.10 in its package.

3. Misplaced Files or Improper Symlinking

– Another possibility leading to libcublas.so.10 load failure is incorrect file placement or incorrect symbolic linking. Sometimes, the file exists but at a different location or under a different name, and hence it cannot be loaded.

– Ensure that the required shared object files are placed correctly in the intended directory structure. Also verify any symbolic links using

ls -la

. If necessary create the required symlinks. Here’s an example how you could create a symlink:

ln -s /usr/local/cuda/lib64/libcublas.so.10 /usr/local/lib/libcublas.so.10

4. Insufficient File Permissions

– Lastly, issues related to privileges or permissions sometimes arises when dealing with library files. Verify if the user executing the script has sufficient permissions to access the files in question.

Does the Issue Persist?

I hope one of the above solutions works for you. However, if the issue persists:

– Look deeper into the error messages to get more clues about what’s going wrong. Sometimes, an error message tells you exactly what’s missing or gives you a hint where to start looking.

– Check the documentation or FAQs provided by Tensorflow or CUDA. Chances are high others have faced similar issues so don’t hesitate to ask the community for help.

Also, consider the importance of keeping your system up-to-date. Open-source libraries like TensorFlow are constantly being improved and bugs are often fixed in new versions. Thus regularly checking for updates, might save you from running into such problems.

Always remember, that the boost you receive in processing speed and capabilities from GPU acceleration in Tensorflow substantially outweighs the initial hurdle in setting it up. By analyzing the cause of the error before sprinting toward disparate solutions, you get to learn more about the inner workings of your tools. Happy coding!One of the common issues encountered in software development is that of shared object files. When dealing with dynamic libraries like libcublas.so.10, often a part of CUDA toolkit, we may encounter an error like “Could Not Load Dynamic Library libcublas.so.10 Dlerror: libcublas.so.10: Cannot Open Shared Object File”. This error message indicates that your code or application is failing to locate or open the dynamic library file libcublas.so.10, and this could stem from several possible reasons.

Incorrect Installation Or Update Of CUDA

A leading reason for this error might be an incorrect or incomplete installation or an update of CUDA on your system. libcublas.so.10 is typically included in the CUDA toolkit, which suggests that if it’s missing or inaccessible, your CUDA installation might be corrupted.

– Solution: Verify your CUDA installation to ensure all necessary files have been installed correctly and are located in appropriate directories. Reinstalling CUDA can also mitigate this issue.

Environment Path Issues

The other primary concern is related to environment path configuration. The dynamic loader searches specific directories to find shared libraries (.so files) based on the environment variable LD_LIBRARY_PATH. If the dynamic library path doesn’t include the directory with libcublas.so.10, or the environment isn’t set accurately, you’ll encounter that error.

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64

– Solution: make sure to set the environment variables correctly in your bashrc script and remember to refresh your terminal, or source the script before running any applications that depend on it.

Version Mismatches

Another probable cause could be version mismatch; for instance, your code might require one version of the library but another is installed on your system.

– Solution: Always make sure the needed version is installed on your system.

Directory Permission Issues

At times, the problem could be due to permission issues. Your program should have adequate permissions to access the required .so files inside your system directories.

– Solution: Check your directory permissions and alter them if necessary.

Remember, always be cautious when modifying shared libraries and paths as these changes could influence other applications and services. For more elaborate guidance on handling shared object files, consider visiting ld.so – dynamic linker/loader Linux man pages.

For example, a Python script will load PyTorch – a deep learning framework that uses CUDA under the hood for highly optimized computations, which might utilize the ‘libcublas.so.10’ shared object:

import torch

# Create random tensors
x = torch.randn(10)
y = torch.randn(10)

# Perform operation on GPU
z = x + y

In this script, the PyTorch library should find (and load) the required shared objects, but if it gets stuck at ‘libculblas.so.10’ the suggestions provided above should come in handy.When dealing with ‘Cannot Open Shared Object File’ issues, it’s often a result of trying to load a shared library that can’t be found. This analysis focuses primarily on the error message

Could not load dynamic library libcublas.so.10 Dlerror: libcublas.so.10: Cannot open shared object file

.

First, let’s give you an understanding of shared libraries. Shared libraries (or dynamically linked libraries) are files written in .so format, containing code and data which multiple programs can use simultaneously during execution. Citing our error case,

libcublas.so.10

is one such shared library.

So, why might the system encounter problems finding or opening these files?

Incorrect File Path

If the library file isn’t situated where the loader expects to find it, you’ll receive the ‘cannot open shared object file’ error. The loader typically uses three paths when searching for shared objects:

• An internal list within the binary itself (RPATH or RUNPATH)
• A bunch of system-defined directories (/lib, /usr/lib)
• The directories listed in the environmental variable LD_LIBRARY_PATH

Given our error message, you should check whether

libcublas.so.10

is in any mentioned locations. If it’s missing or in an unexpected place, correct its location.

Inappropriate Version

Even if your library is located correctly, an incorrect version can cause trouble. The error explicitly mentions

libcublas.so.10

, implying it specifically requires this version of the library. If another version is installed (for example, libcublas.so.11), it won’t work. You’ll need to install the required version.

Wrong Architecture

Shared Libraries are compiled for particular architectures, such as x86 or ARM, meaning they’re not cross-compatible between them. Trying to load a library compiled for a different architecture generates the ‘cannot open shared object file’ error. Verify your system’s architecture and ensure your libraries match it.

To resolve our issue “Could not load dynamic library libcublas.so.10 Dlerror: libcublas.so.10: Cannot open shared object file”, possible solutions include:

• Locating

  libcublas.so.10

  and adjusting the LD_LIBRARY_PATH variable:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/library

• Identify the appropriate version of your CUDA toolkit which provides

  libcublas.so.10

  and ensure it’s installed. Nvidia’s official CUDA Archive source will help.

• If your existing libcublas library was for a wrong architecture, rebuild or reinstall it for your correct one.

It’s essential to ensure quick identification and resolution of ‘Could not load dynamic library libcublas.so.10 Dlerror: libcublas.so.10: Cannot open shared object file’ errors as such issues could hinder performance and effective utilisation of resources. They also pose a risk of crashing the system or making the system unreliable. Reliable software always results from efficient coding and debugging practices, ensuring smooth operation and long-term sustainability.The error “Could not load dynamic library libcublas.so.10 dlerror: libcublas.so.10: cannot open shared object file” is a common problem typically experienced by developers when working with graphics card dependent libraries in certain Linux distributions. This hinders the smooth running of other associated programs that rely on these dynamically linked libraries, therefore ensuring it’s quickly and effectively resolved is key to getting back to work. The root cause revolves around the operating system not being able to find the specified dependency – in this case, the “libcublas.so.10”.

First off, we must acknowledge that Dynamic Link Libraries (DLLs) form the bedrock of sharing code and resources across multiple projects as they provide numerous advantages such as:

• Modular programming
• Memory efficiency
• Easier deployment and installation

#Code snippet showing an example of how DLL files might be utilized in C++
HMODULE hModule = LoadLibrary(L"MyDynamicLinkLibrary.dll");
typedef void (*FunctionType)(int);
FunctionType Function = (FunctionType)GetProcAddress(hModule, "MyFunction");
Function(10);
FreeLibrary(hModule);

Consequently, when a DLL failure such as ‘Could Not Load Dynamic Library libcublas.so.10’ occurs, it disrupts functionalities and can halt whole processes.

Troubleshooting Techniques for This Issue:

1. Double-check that you have installed the correct version of CUDA on your computer. This error often occurs because an incorrect or incompatible version of CUDA was installed. So it would be worthwhile to check which version you are using and if it matches the specifications required for your project.

2. Sometimes, the cause might be a wrong or missing environment variable. Setting the environment variable LD_LIBRARY_PATH can be done easily through the shell you’re currently using.

    export LD_LIBRARY_PATH=/usr/local/cuda/lib64
    

3. Occasionally, the problem may arise from a poorly configured package during installation. In such instances, reinstalling the CUDA toolkit may solve the problem. Don’t forget to delete any residual files from previous installations before doing so. Here is NVIDIA’s link to their most up-to-date versions.

4. Finally, after reinstallation, confirm if libcublas.so.10 has been correctly loaded to its appropriate directory. Validate it using the ‘ldconfig’ command line utility or manually via searching through ‘/usr/local/cuda/lib64’.

Remember, troubleshooting is essentially a trial-and-error approach used to diagnose and repair faults plaguing a system. Therefore, the methodology suggested here isn’t foolproof but rather offers direction towards identifying and rectifying the routine forces at play driving the problematic behavior encountered.

Reference LinkIn the realm of coding and software operation, the alert “Could not load dynamic library libcublas.so.10 dlerror: libcublas.so.10: cannot open shared object file” indicates a problem you may have encountered – a missing or inaccessible dynamic library file called

libcublas.so.10

. Let’s look at how the operating system reacts to this issue and possible solutions involved.

An Overview

To start, let’s ensure we understand the import of the error message:

• "Could not load dynamic library "

  : This posits that your application was designed and compiled using dynamic linking, which includes specific versions of dynamic libraries such as

  libcublas.so.10

  . And it’s currently facing difficulty in loading that required library.

• "libcublas.so.10: cannot open shared object file"

  : This section intimates there is difficulty opening the necessary dynamic/shared library file. Either such file doesn’t exist on your system or if it does; maybe it can’t be accessed due to permission restrictions or incorrect paths.

Dissecting The Problem further

When an operating system is unable to locate a library like

libcublas.so.10

, it typically responds with such errors because your software relies on it for functionality. For example,

libcublas.so.10

serves as a CUDA library from Nvidia for GPU-accelerated basic linear algebra calculations.source.

Here are two primary reasons why you might be receiving this error:

• The library installation is not done: Most likely, you’ve installed CUDA but the version doesn’t match the one necessary for your software.
• Environment variables misconfiguration:“.so files” like libcublas.so.10 take up their direction from environment variables. An improper setup could lead them into not being found when required.

Solutions To Consider

Now that we’ve identified potential causes for the error, let’s explore possible solutions:

• Correct Installation of the Library: You’ll need to install the appropriate version of

  libcublas.so.10

  the error message refers to. With Ubuntu, this can be achieved via terminal command:
  

  sudo apt-get install libcublas10
  

  This installs the library in your operating system’s standard library path, enabling applications to find it.

• Set Environment Variables: Your environment variables, especially

  LD_LIBRARY_PATH

  , should receive attention. When running an application,

  LD_LIBRARY_PATH

  is checked for locations of .so files. If the path isn’t accurately set, these libraries will not be found. You can modify and export this path in bash shell by:
  

  export LD_LIBRARY_PATH=/your-library-path:$LD_LIBRARY_PATH
  

  This adds your custom path to the already existing library path.

• Symbolic Linking: Libraries often have different versions co-existing on a system. If the newer version is backwards compatible, a symbolic link can be created to point to the requested older version towards the new library version.
  For example:

  sudo ln -s /usr/local/cuda/lib64/libcublast.so.11 /usr/local/cuda/lib64/libcublast.so.10
  

Remember, whichever solution employed, routines involving updating system wide library directories or symbolic links should be handled carefully. Mismanagement here could lead to other unpredictable system bugs or security issues.

Finally, the above-mentioned solutions ensure that at runtime, any program needing

libcublas.so.10

will find the library at the expected spot, averting errors like “Could not load dynamic library libcublas.so.10 Dlerror: libcublas.so.10: Cannot Open Shared Object File”.The issue of the system unable to locate and load ‘libcublas.so.10’ file occurs due to the absence of a specific version of the cublas library in the system. This problem is frequent among people working with CUDA-enabled applications on Linux machines.

What contributes to this error?

1. Incompatible CUDA version: If the application explicitly requires another version than one installed in your system, the error may occur.

2. Absence of the correct PATH: The compute unified device architecture(CUDA) toolkit’s location should be included in the system path for the application to find the required libraries.

So let’s dissect each contributing factor and offer potential solutions.

Addressing Incompatible CUDA Version

Sometimes an older version of CUDA might be installed on your system, but the application you are trying to run requires a newer version or specifically ‘libcublas.so.10’. Hence, you’ll require matching your system’s CUDA version with the one needed by your application.

You can use the following procedure to upgrade or downgrade your system’s CUDA version:

– Uninstall the current version of CUDA:

    sudo apt-get --purge remove cuda
    

– Download the desired CUDA toolkit from the official NVIDIA archive.

– Install the downloaded CUDA toolkit:

    sudo dpkg -i cuda-repo-ubuntu1604-10-0-local-10.0.130-410.48_1.0-1_amd64.deb
    

– Update the package lists for the system to know about the CUDA files:

    sudo apt-get update
    

– Finally, install the CUDA toolkit:

    sudo apt-get install cuda
    

Setting Correct Environment Variables

Even when the appropriate CUDA version is installed, if environment variables aren’t set correctly to include CUDA’s path, the system won’t be able to find it. To successfully load dynamic library libcublas.so.10, adjust the PATH and LD_LIBRARY_PATH variables as such:

– Edit ~/.bashrc file using a text editor:

    nano ~/.bashrc
    

– Add at the end of the file:

    export PATH=/usr/local/cuda-10.0/bin${PATH:+:${PATH}}
    export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
    

– Save and close the file.

– Test the new settings:

    source ~/.bashrc
    

    nvcc -V
    

If executed properly, the system will return information about the newly installed CUDA version. By understanding the roots of the libcublas.so.10 failure to load, we’re able to formulate these troubleshooting strategies to address and resolve the complication effectively. It all boils down to ensuring compatibility between the CUDA version requested by the application and the one present on the machine, while making certain that relevant paths have been appropriately set.As a professional coder, the errors related to “Could not load dynamic library libcublas.so.10 Dlerror: libcublas.so.10: cannot open shared object file”, which essentially indicate a failure in loading a specific dynamic library, can be effectively addressed by ensuring complete installation of the required packages for your development environment.

The dynamic library libcublas.so.10
The

libcublas.so.10

error is predominantly associated with NVIDIA’s CUDA software. The cuda-cublas library is part of the CUDA Toolkit, used for general purpose computing on GPUs. Seeing this error implies that this library isn’t installed or available for usage in the PATH. So to get rid of such an error, it becomes crucial to make sure that the package (in this case CUDA) and its associated libraries are all correctly installed.

Addressing the error via Ensuring Complete Installation
To prevent the error from cropping up, here is a step-by-step guideline:

– First, download the specific version of CUDA toolkit that’s compatible with the applications you’re running and the GPU drivers installed.
– Proceed with the installation as per the provided instructions – ensure to include the cublas library during installation.
– Post-installation, validate that your shell’s PATH includes the location of the installed CUDA bin directory.
– It’s also essential that your LD_LIBRARY_PATH has been updated to include the CUDA lib64 directory. The steps would look similar to the below code:

export PATH=/usr/local/cuda-10.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

Remember, while using these commands, replace

cuda-10.0

with the respective CUDA version installed.

Should any one of the paths be incorrectly set, the system won’t be able to access the right libraries, thus causing the said error.

In addition to ensuring a complete installation, keep a check on potential inconsistencies between versions of various installed packages, especially when dealing with graphics drivers, CUDA toolkit and cuDNN. Any mismatch can also lead to the same error. If you observe such incompatibility, it’d be apt to align all components to referenced compatible versions.

For more details on CUDA installation, you can visit NVIDIA’s official CUDA installation guide here.

Additional Tip
Another possible cause of the error could be Docker overriding the LD_LIBRARY_PATH. In such instances, creating a symbolic link for

/usr/lib/x86_64-linux-gnu

to

/usr/local/nvidia/lib64

could resolve the error.

sudo ln -s /usr/local/nvidia/lib64/libcublas.so.10 /usr/lib/x86_64-linux-gnu/libcublas.so.10

By following these steps, and ensuring a comprehensive installation, we can correct the error resulting from failing to load the dynamic library

libcublas.so.10

. Such relevant mindfulness regarding system configurations and outlining the purpose of each of these steps serves beneficial to both new and experienced coders, thereby facilitating smoother software compilation processes.Let’s delve into how the CUDA Toolkit ties in with libculbas.so.xx issues, particularly concerning the specific problem: “could not load dynamic library libcublas.so.10 dlerror: libcublas.so.10: cannot open shared object file”.

The CUDA Toolkit is essentially an extensive software stack that permits developers to utilize NVIDIA’s GPUs (Graphics Processing Units) power for multiple computational tasks. This toolkit encompasses libraries like `libcublas`, which provides GPU-accelerated implementation of the basic linear algebra subprograms (BLAS).

When you install the CUDA Toolkit, these essential libraries are also installed in the provided CUDA installation directory. The regular directory path looks something similar to this:

/usr/local/cuda/lib64/

If a program or application, such as TensorFlow, is configured to use CUDA, it dynamically loads the needed CUDA libraries (`*.so` files) during its execution. However, if the system couldn’t find these library files, it leads to errors like “could not load dynamic library libcublas.so.10 dlerror: libcublas.so.10: cannot open shared object file” signifying that the specific version of the `libcublas` library has been sought but is unavailable.

To resolve this issue, there are two main aspects you need to check:

1. Ensure you have the correct version of the CUDA toolkit installed. Simply, if your program needs libcublas.so.10, you need to have the CUDA Toolkit version 10.x installed because libcublas.so.10 is part of CUDA version 10.

2. Validate if the CUDA libraries (including libcublas.so.10) are accessible via your system’s library path. You can append the appropriate CUDA library path to the LD_LIBRARY_PATH environment variable:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-10.x/lib64/

Replace ‘x’ with your specific minor version number. Run the above command each time before executing your CUDA-based program, or add it to your .bashrc file to make it permanent.

Remember, mismatched versions between CUDA and the deep-learning frameworks can cause problems, so always verify the required CUDA Toolkit version whenever you encounter similar issues [ref](https://askubuntu.com/questions/1077061/how-do-i-install-nvidia-and-cuda-drivers-into-ubuntu).
After setting everything right, the error should disappear and your CUDA-based programs should work smoothly leveraging the power of GPU acceleration provided by the CUDA libraries.The error message “Could Not Load Dynamic Library Libcublas.So.10 Dlerror: Libcublas.So.10: Cannot Open Shared Object File” indicates that the system was unable to find the shared object file libcublas.so.10, a critical library file linked to running CUDA applications, specifically the cuBLAS library, which is an NVIDIA GPU-accelerated Basic Linear Algebra Subprograms (BLAS) library.

Solution Steps:

1. Check Installed CUDA Version
2. Verify Library's Presence and Location
3. Set Up Environment Variables
4. Restart The System

Let’s take a deep dive into this:

1. Check Installed CUDA Version: The first place to look would be your CUDA version. Ensure that you have the correct version installed by running

nvcc --version

in your terminal.

2. Verify Library’s Presence and Location: Once you’ve confirmed the CUDA version, the next step is to ensure that the libcublas.so.10 file exists on your system and confirm its location. For a typical install of CUDA, it should be under

/usr/local/cuda/lib64

. Navigate to this directory and check if the file is there using

ls libcublas* 

.

3. Set Up Environment Variables: If the files are present and still inaccessible, it’s likely an issue with your LD_LIBRARY_PATH environment variable not including the path to the CUDA libraries.

In your bash profile (e.g., .bashrc or .bash_profile), include these lines:

export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

4. Restart The System: Having made these changes, you will need to restart your terminal session or source the edited bash profile for the changes to take effect. Example: If you edited .bashrc, then do

source ~/.bashrc

.

Note: Please replace

/usr/local/cuda

with the actual path where CUDA is installed if it’s different in your case.

The steps outlined above should resolve the issue and make it possible for your applications to access the dynamic library libcublas.so.10.

For further clarification, I recommend checking the official NVIDIA documentation^[1].
