Thanks for digging into this and sorry I have missed that. I typically add export http*_proxy to prevent any network interactions but I guess didn't get that far with statsmodels.
FWIW, for dipy package I now ask upstream to provide me e.g. dipy_0.12.0.orig-doc-examples.tar.gz where there are examples, which require lengthy computation to produce doc pieces To resolve this issue quickly, I might have also simply patched/excluded those examples/docs which require external datasets (especially with incompatible terms), from building. -- Yaroslav O.
