Issues running Python on Hamilton

[barnabycollins]

Okay, so potentially stupid question incoming:

I've got myself all set up on Hamilton and have run:

module load gcc intelmpi openblas python

as written on the coursework spec. However, the command python3.9 still doesn't work. I'm pretty sure this is because the newest Python install on Hamilton is 3.6.8; running module avail only lists 2.7.1, 2.7.9, 2.7.11, 2.7.13, 3.5.1 and 3.6.8. The command module list shows that python/3.6.8 and python/ompi/2.7.13 have been loaded.

So I've gone ahead with running python3.6 instead, and it's at least running something, but now I'm getting the following error as soon as I try and do anything at all with it:

ModuleNotFoundError: No module named 'encodings'

Current thread 0x00002ac8e181d900 (most recent call first):
Aborted

Am I doing something wrong here? 😅 Also, just to check - does loading Python 3 override the pip command from the default Python 2.7 to the Python 3 environment, or should we use python3.x -m pip ... instead?

TIA!

Are you running on Hamilton 7 (hamilton.dur.ac.uk) which is end-of-life after Easter? Or Hamilton 8 (hamilton8.dur.ac.uk)? If the former, try switching to the latter.

As regards the pip question, you'll want to create a venv (with python3.9 -m venv ...), activate it, and then pip will be the one in your virtual environment.

Hi - yeah, I was on Hamilton 7; I forgot they hadn't changed hamilton.dur.ac.uk to point to the new machines yet.

My bad; thank you!
