Kernel hangs with cufflinks

[ratnesh1729]

import pandas as pd
import cufflinks as cf
cf.go_offline()

-- If we have above imports and try to execute cell - the kernel and the whole emacs hangs. Only way to get out is to restart/kill emacs.

Let me know if we need more details. Doing above on Jupyter/browser does not hand anything and works smoothly.

Best,

I'm able to replicate the issue with the following:

import pkgutil
pkgutil.get_data('plotly', 'package_data/plotly.min.js')

min.js files are usually one massive line. EIN suffers the same performance issues as emacs when it comes to long lines. I'm afraid you'll need to go back to the web client, which is just as well since plotly and cufflinks appear at first glance to be very javascript-centric, and EIN is anathema to web languages.

Cufflinks is something of a wrapper around pandas and plotly. Plotly displays its graphs in the browser-based jupyter client using javascript, something which Emacs just simply does not grok. Something like skewer might work, but I just haven't had the time this past year to look much into implementing this support. I think a user did have some partial success - you might want to look at issue #65.

Will only think about this if webkit integrates with emacs (unlikely).
