ModuleNotFoundError: No module named 'vaex.ext.bqplot'

[tigikay]

Just started using vaex, trying to 3d plot galaxy sim, 2D plots work. Installed bqplot seperately - still not recognised by vaex.

Full error is:

Using Python3, installed vaex through pip3. Using conda ruined a lot of stuff, so not risking it atm

Edit: vaex.ext is completely empty and for some reason I can't find it in the vaex repository

Hi,

does ds.plot_widget('x', 'y') work, after that try, ds.plot_widget('x', 'y', 'z', backend='ipyvolume'). I should fix plot3d, but meanwhile this should work. What went wrong with conda btw, did it had sth to do with vaex?

cheers,

Maarten

Same problem here! Installed via Conda. Trying to use plot_bq

[maartenbreddels]

Hi,

thanks for the report, I need to make plot_bq also backwards compatible, for now use ds.plot_widget('x', 'y').

Regards,

Maarten

Hi, Thanks for creating and sharing this awesome framework! experiencing the same error with plot_bq, on both python 2.7 and 3.6 environments, built specifically for this (on a machine running ubuntu) when trying to work with plot_widget i get- "No module named 'vaex.jupyter'" on the 3.6 env "No module named jupyter.plot" on the 2.7 env both stemming from "import vaex.jupyter.plot" on dataframe.py

Any news on this? vaexgui is unusable and beyond repair.
