 Error message "GPU version of Tensor Library is not installed or not detected" when trying to classify pointcloud

Hi all,

Does anyone have a solution for TBC not being able to detect my GPU (NVIDIA RTX A3000). I have updated the drivers, it is available in device manager, but every time I try to classify a point cloud it says it will fall back on CPU instead.

I have set TBC to use the high performance graphics card in my graphics settings, and restarted my computer many times. 

Side note: this was working correctly last week, but I had to re-install TBC and now the GPU is not detected.

Thanks in advance!

Have you changed the graphics mode (in options) to OpenGL and restarted TBC?

I have tried changing the graphics display driver to OpenGL2 and restarted with no success. I have also tried using DirectX 11, and it doesn't solve the issue either. I am going to try and install some new GPU libraries to see if this helps

Hi Henry,
The error message indicated that the installed NVIDIA CUDA driver was older than the CUDA runtime library, leading TBC to fall back on CPU operations.
 
Solution:
 
Update NVIDIA Driver:
 
Visit the NVIDIA Driver Download page.
Select your GPU model (NVIDIA RTX A3000) and operating system.
Download and install the latest driver available.
Restart your computer.
Install CUDA Toolkit:
 
Go to the CUDA Toolkit Downloads page.  https://developer.nvidia.com/cuda-downloads?target_os=Windows&target_arch=x86_64&target_version=10&target_type=exe_local 
Download and install the latest CUDA Toolkit compatible with your GPU.
Ensure that the installation paths are correctly added to your system environment variables.
Verify Installation:
 
Open a Command Prompt and run nvcc --version to check the CUDA compiler installation.
 
 
After following these steps, TBC should successfully detect your GPU, enabling point cloud classification with GPU support

Hi Ramin,

Thank you very much for the directions.

I have followed them all, and I am still getting the same error message. I have confirmed I am running the latest NVIDIA driver and the latest CUDA toolkit is working using command prompt.

When this didn't work, I have also tried uninstalling TBC, and reinstalling it. Still no success.

Do you have any other suggestions? I will gladly take any further advice.

Thanks again,

Henry
