ImportError: cannot import name '_png' from 'matplotlib'

Hi, while trying out the fbprophet tutorial, I encountered the following error log when attempting to execute in jupyter notebook the following code: fig1 = m.plot(forecast)

The error log is as follows:

I tried updating matplotlib to 3.3.2 but the problem still persists. Please advise, am in need of urgent assistance…Thanks in advance.

try this pip install matplotlib==3.1.3 work for me

Why is this issue closed? There should be a solution which works for latest matplotlib versions. Downgrading for most people is not an option.
