Hi!
I just installed Prophet, however, when I type:
from fbprophet import Prophet
I get this error:
ImportError: cannot import name 'MONDAY'
I ran: pip install fbprophet --upgrade before asking the question, and even with that I got the same error.
Any suggestion on how to overcome this error, would be extremelly welcome...

It seems like a new release of holidays (0.9.9) earlier today is causing errors with Prophet.

from fbprophet import Prophet
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/site-packages/fbprophet/__init__.py", line 8, in <module>
    from fbprophet.forecaster import Prophet

    import fbprophet.hdays as hdays_part2

    from holidays import HolidayBase, MONDAY, WEEKEND, rd, easter
ImportError: cannot import name 'MONDAY'

I rolled back to holidays 0.9.8 and am now able to import Prophet.

pip uninstall holidays
pip install holidays==0.9.8
