How to get the cuda version?

Question

Is there any quick command or script to check for the version of CUDA installed?

I found the manual of 4.0 under the installation directory but I\'m not sure whether

Answer 1

Use the following command to check CUDA installation by Conda:

conda list cudatoolkit

And the following command to check CUDNN version installed by conda:

conda list cudnn

If you want to install/update CUDA and CUDNN through CONDA, please use the following commands:

conda install -c anaconda cudatoolkit
conda install -c anaconda cudnn

Alternatively you can use following commands to check CUDA installation:

nvidia-smi

OR

nvcc --version

If you are using tensorflow-gpu through Anaconda package (You can verify this by simply opening Python in console and check if the default python shows Anaconda, Inc. when it starts, or you can run which python and check the location), then manually installing CUDA and CUDNN will most probably not work. You will have to update through conda instead.

If you want to install CUDA, CUDNN, or tensorflow-gpu manually, you can check out the instructions here https://www.tensorflow.org/install/gpu
