ImportError: cannot import name 'factorial'

[caizd1994]

from causalml.inference.meta import BaseSRegressor, BaseTRegressor, BaseXRegressor, BaseRRegressor ----> 7 from scipy.misc import factorial

ImportError: cannot import name 'factorial

requirement.txt ask scipy==1.4.0 but where scipy >= 1.3 factorial is not in misc

Expected behavior update the package

Hi @caizd1994, thanks for using causalml and reporting this. In our most recent requiremnt.txt we are using scipy==1.14.1 because of the tensorflow requirement. I wasn't able to reproduce this bug, as shown in the below screenshot.

Could you try to remove any cached or previous installation of causalml and install it again?

# from somewhere not in the causalml source directory
$ pip uninstall causalml 
$ pip install --no-cache-dir -U causalml

Please let me know if it helps.

Hi, it seems this problem actually coming from statsmodels. I also saw similar issue here been discussed. What's the statsmodels version you are using? Could you upgrade to statsmodels>=0.9.0? Thanks!

Hi @caizd1994, just want to check-in to see if you still have this issue? Thanks!

forced upgrade of statsmodels fixes this issue and installing a 1.4.0 version of scipy too
