I have tried importing the data in different ways
data_path = 'https://raw.githubusercontent.com/PinkWink/DataScience/master/data/07.%20example_wp_peyton_manning.csv'
peyton = pd.read_csv(data_path)
peyton = pd.read_csv('07. example_wp_peyton_manning.csv')
But the error persists.
In order to see if it was due to the number of libraries imported (as these notebook already has quite a few), I have tried importing only
FBProphet, but the error persists.
Are you using IPython kernel or Datalore kernel? (If IPython kernel, which is the same as me, it may be due to the the fact that my environment, apart from fbprophet=0.7.1 has also installed pmdarima=1.7.1.)
As I was working in Home, I will create a Workspace and create the notebook there to see if the problem lies here.
