get the CUDA and CUDNN version on windows with Anaconda installe

Question

There is a tensorflow-gpu version installed on Windows using Anaconda, how to check the CUDA and CUDNN version of it? Thanks.

Answer 1

You could also run conda list from the anaconda command line:

conda list cudnn

# packages in environment at C:\Anaconda2:
#
# Name                    Version                   Build  Channel
cudnn                     6.0                           0

Answer 2

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

Answer 3

Although not a public documented API, you can currently access it like this:

from tensorflow.python.platform import build_info as tf_build_info
print(tf_build_info.cuda_version_number)
# 9.0 in v1.10.0
print(tf_build_info.cudnn_version_number)
# 7 in v1.10.0
