pip has old source code? #14

Closed KCrux closed 1 year ago

KCrux commented 1 year ago

Hello,

I installed baycomp today with 'python -m pip install baycomp' and tried to use the 'two_on_multiple' function.

Then I got the error message: 'ImportError: Hierarchical model requires 'pystan'; install it by 'pip install pystan''

According to the latest update of the source code this shoud be fixed already. But it seems like that this update wasn't posted to PyPI? On the website https://pypi.org/project/baycomp/#files the latest version is 1.0.2 from 2019 and this is the version i got with pip install, too.

Maybe you want to update this? :-)

I think you're correct in that the latest updates haven't been posted to PyPI.

However, even with those latest updates you will get a similar error about pystan missing since that is an optional dependency (only the hierarchical model requires it) that you have to install by hand.

Note that you should be able to install the latest version from GitHub using

pip install git+https://github.com/janezd/baycomp.git

Thank you for your fast answer.

I think I expressed myself a bit unfortunate. My point is that you get this error after installing pystan ;-). It's fine that pystan is optional, but baycomp should worker after installing it.
