I've noticed that field install_requires was not filled at setup.py.
Hence, the dependencies are not installed through pip command.
I've installed the dependencies through apt-get build-dep python-statsmodels that could not be last one (pip can be more updated).
apt-get build-dep python-statsmodels
Could statsmodel do it for us?
Very best regards,
So far we have avoided letting pip resolve the dependencies on purpose due to pip's recursive upgrade behavior IIRC.
@emanuelvianna see gh-1897 for more details. This is a duplicate of that and several other issues, so closing.
