ImportError: LogNormalFitter, LogLogisticFitter, PiecewiseExponentialFitter

See original GitHub issue

I am having issues importing the following subpackages:

from lifelines import LogNormalFitter
from lifelines import LogLogisticFitter
from lifelines import PiecewiseExponentialFitter

The error message is:

ImportError: cannot import name 'LogNormalFitter' from 'lifelines' (C:\Users\AppData\Local\Continuum\anaconda3\lib\site-packages\lifelines\__init__.py)

Any ideas what the problem might be?

Thank you, c.

Yes, I’m having Anaconda problems. I really don’t know how to fix these but I’ll follow your suggestions.

Thank you for your help, Ceren

Unfortunately, I can’t help you with conda problems (as it look like in this case). Something googling suggests fixes: https://stackoverflow.com/questions/50125472/issues-with-installing-python-libraries-on-windows-condahttperror-http-000-co

Also, you say:

conda update pipelines

Did you mean lifelines?
