Prophet: ImportError: cannot import name 'pythran_is_numpy_func_supported'

[brijeshdankhara]

Can not import using from fbprophet import Prophet. I am testing fbprophet for the first time, using a Jupyter Notebook for test and I run into error message below. I couldn't find any resource to debug this in context to fbprophet, please point me to the resource, if available.

Thanks for all the help.

This is a cython package issue. I was able to correctly import fbprophet with cython 0.29.6

Closing the issue.

pip uninstall cython--> repeatedly until your system is clear

then
pip install cython

in my case.

ImportError: cannot import name 'Prophet' from partially initialized module 'fbprophet' (most likely due to a circular import) (/Users/Naropa/Downloads/python/fbprophet.py)
