If you need to run a specific version of Python, you can Upgrade or Downgrade Python Conda on nvidia/cuda Docker as shown in this tutorial.

1. Attach a terminal to the running docker.

fyicenter# docker exec -it my_cuda /bin/bash 

(base) root@e4395c83ac54:/# 

2. Install "pip" in the default Conda environment "base".

(base) root@e4395c83ac54:/# conda install -y -c conda-forge pip

4. Verify Python version inside Conda.

(base) root@e4395c83ac54:/# python --version 

Python 3.7.10

5. Verify Python version outside Conda.

(base) root@e4395c83ac54:/# conda deactivate 

root@e4395c83ac54:/# python --version 
  bash: python: command not found

6. Create a new Conda environment with Python 3.9.

root@e4395c83ac54:/# conda create -n py3.9 
  environment location: /opt/conda/envs/py3.9

root@e4395c83ac54:/# conda activate py3.9
(py3.9) root@e4395c83ac54:/# 

7. Upgrade the new Conda environment to Python 3.9.

(py3.9) root@e4395c83ac54:/# conda install -y -c conda-forge python=3.9

8. Verify Python version in both Conda environmwnts:

(py3.9) root@e4395c83ac54:/# python --version 
  Python 3.9.6

(py3.9) root@e4395c83ac54:/# conda activate base 

(base) root@e4395c83ac54:/# python --version
  Python 3.7.10
