statsmodel version #169

Closed mac133k closed 3 years ago

mac133k commented 3 years ago

I built a Docker container from the master branch. The build completed with the errors:

statsmodels 0.12.2 has requirement scipy>=1.1, but you'll have scipy 0.19.1 which is incompatible.
aiohttp 3.7.3 has requirement chardet<4.0,>=2.0, but you'll have chardet 4.0.0 which is incompatible.

This makes zipline unusable due to version conflict:

raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (scipy 0.19.1 (/usr/local/lib/python3.6/site-packages), Requirement.parse('scipy>=1.1'), {'statsmodels'})

Is there a quick fix or a workaround I could use? I tried to change version numbers for the built, but that lead to other errors.

Regards, MS

Ok, I think I fixed it by removing version numbers from the Dockerfile, so the container was built with the latest versions. One version conflict still remained: aiohttp/chardet - that was resolved by:

!pip3 install aiohttp --upgrade

run in the notebook on the container.

thanks. you should use the released version since the dev branch (master) has some issues we need to resolve. but will fix them soon
