Installation fails for scipy on Ubuntu 20.10

[sangaman]

I can't install this either using option 1 or option 2 from the instructions with the same error while building scipy. I'm using python 3.8.6 on Ubuntu 20.10. I've tried installing the following dependencies: sudo apt install python3-testresources gfortran python3-dev libblas3 liblapack3 liblapack-dev libblas-dev libatlas-base-dev python3-scipy

Here's a snippet of the error output (there's a lot of it):

Hi,

You can see in the requirements that scipy 1.2.1 is needed. It is an old version that, AFAIK, cannot be installed with python 3.8.
I had a similar issue and moving from python 3.8 to 3.7 fixed it.

Hope this helps.
