Installation issues

see https://github.com/eos/eos/issues/411 for error messages.

After closing the issue, the same error cropped up again even though I didn't reinstall pypmc:

at 21:42:27 ❯ python3.8 -c "import pypmc"
Traceback (most recent call last):

ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

The error may come from the fact that numpy was picked up from the ubuntu repos and other python modules may come with a different version? It should go away in a venv with all dependencies compatible

Closing as outdated, given that we now build wheels against the stable numpy API.
