I have a python project which relies on pystan (for fbprophet). As part of a CI/CD workflow I am trying to set up jenkins to build the images and push to a docker registry. However, the pip installation of pystan is super slow. Seems to be stuck at this stage for 10+ minutes:
Building wheels for collected packages: pystan, pymeeus
Building wheel for pystan (setup.py): started
Building wheel for pystan (setup.py): still running ...
Jenkins appears to become unresponsive on a t2.medium anytime I try to build the image.
Is there another way to install pystan? Download the wheels beforehand? How can I figure out what is making it so slow?
I could potentially start form a base docker image which already has pystan installed perhaps?
PyStan currently provides a number of precompiled wheels for different platforms and Python versions except for Python 3.8.
Can I guess you use Python 3.8? Try downgrading to 3.7 — pip should install PyStan without compilation.
