Installation error (venv): no module named numpy

Not sure this is pebcak, so decided to report it.

Following the installation instructions here I ran into the following error while executing the command pip install -r requirements.txt in a virtualenv:

Collecting CVXcanon>=0.0.22 (from cvxpy<1.0.0,>=0.4.11->-r requirements.txt (line 6))

        import numpy
    ImportError: No module named numpy

After manually installing numpy first with pip install numpy, pip was able to continue installing the other requirements.

Thanks for reporting. It is strange this happens though, because numpy is already in requirements.txt
