error installing Theano (virtualEnv with python 3.7, running on Ubuntu 20)

[guyam2]

Hello!
I'm trying to install Theano on my virtual environment, running on Ubuntu 20, and python 3.7 and I'm having some issues.

No matter what I do - when I try to install the package directly ("pip3 install ...") or via PyCharm - it won't work. I always get the following error:

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProtocolError('Connection aborted.', OSError(0, 'Error'))': /simple/theano/

I made sure that all the required packages (numpy, scipy etc) are installed with correct versions, and also I added the defualt timout=1000 flag when attempting to install - and it still won't work.

Can you please help me out?

Thanks very much for your help!
