Does the magic %matplotlib inline fix it in the notebook?

[mas-dse-juremigi]

[dhuanca]

really works! thank you! -.-'

[francica]

where should I run %matplotlib inline?
In bash? or in the py file?

thanks

The latest images should automatically default to the inline matplotlib backend. docker pull to get the latest if you haven't recently.

I face the same problem too despite using
%matplotlib inline #plots it on the notebook itself

The error message for the code is as follows:

I am new to programming and I am learning as much as I can through the internet, any help would be much appreciated as this is hindering my progress!

Thanks, it works fine
