matplotlib not working in Jupyter lab - anaconda

Question

import matplotlib and
%matplotlib inline are not working. Getting the following errors.
On the anaconda prompt I ran this command as well.
conda install matplotlib
Even after this, this did not work.
Just observed a strange thing.
When I launched using the command jupyter lab from the anaconda prompt, microsoft edge browser launched. And in that this works fine. But when I opened in chrome browser, this gives the problem.

Answer 1

I am not sure why, pasting the entire url generated from the anaconda prompt worked.
So I did the following.
installed the matplotlib using the command conda install matplotlib
Then typed the command jupyter lab.
Then pasted the entire url shown as follows in the chrome browser. Then it working.

Indeed, in the conda documentation - browser compatibility section, you can read:
The Jupyter Notebook aims to support the latest versions of these browsers:
Chrome
Safari
Firefox
Up to date versions of Opera and Edge may also work, but if they don’t, please use one of the supported browsers.
Using Safari with HTTPS and an untrusted certificate is known to not work (websockets will fail).
You might consider to set up one of the compatible browsers as your default to avoid having to copy/paste the url every time.
