Install on ubuntu fails

[biquad]

Hi,

I have problems installing the package on ubuntu 20.04.
Following some initial attempts, I started with a fresh new environment, tried to install punctuator2 (see result below), then went back and checked which components had been installed already

**- python3 -m venv p38.10

• . p38.10/bin/activate
• python -m pip install punctuator [failed, see below]
• python -m pip install wheel theano nltk gdown numpy scipy scikit-learn [these are listed in the requirements.txt file]
  **
  the output of the last command was

Requirement already satisfied: wheel in ./p38.10/lib/python3.8/site-packages (0.37.1)

As far as I can see, the requirements are met.

Nevertheless, I get a blas related error when I try to install punctuator:

Any idea about where the problem is?

Best regards,

Follow-up:
The problem is related to theano that will not install on my Linux system (Ubuntu 20.04 with a pathetic graphics card - NVIDIA GeForce GT 710).
If I find a solution, I will let you know,
Carsten
