Plotting Error with Matplotlib in notebooks

[fififionaz]

When I try to plot in matplotlib, I get the following. I have to update the matplotlib version and then restart the kernel to get around it.

AttributeErrorTraceback (most recent call last)
/opt/conda/envs/python2/lib/python2.7/site-packages/ipykernel/pylab/backend_inline.pyc in show(close, block)

40 )

/opt/conda/envs/python2/lib/python2.7/site-packages/ipykernel/pylab/backend_inline.pyc in _fetch_figure_metadata(fig)
172 """Get some metadata to help with displaying a figure."""
173 # determine if a background is needed for legibility

175 # the background is transparent
176 ticksLight = _is_light([label.get_color()

193 def _is_transparent(color):
194 """Determine transparency from alpha."""

196 return rgba[3] < .5

AttributeError: 'module' object has no attribute 'to_rgba'

@fififionaz Thanks for reporting this. Can you please let me know the exact tutorial notebook and cell where you're getting this error so that I can attempt to reproduce? fyi, you may have an old version of the image.. try running docker pull probcomp/notebook and see if that helps.
