A common issue is if other things are installed in ~/.local or /usr/local  
doing the following would likely provide the information of what is seen:  
$ pip -v list | egrep “torch|tensorflow”

So if you are inside a virtual environment (Anaconda or python venv) it would ‘hide’ the system installed packages.

To version you CUDA you can use a virtual environment or docker container.  
I have a number of examples at:

We should have better write up soon at ‘[http://docs.lambdalabs.com/’](http://docs.lambdalabs.com/%E2%80%99)
