Requesting update the pymc3 package

[HinLeung622]

• Describe the current behavior:
  pymc3.summary(trace) returns TypeError: concat() got an unexpected keyword argument 'join_axes'

• Describe the expected behavior:
  A pandas dataframe should be displayed with summaries of variables in the trace

This issue is caused by pandas being updated to v1.0, but pymc3 was not, see this pymc3 issue for reference: pymc-devs/pymc#3805

P.S. Could you also add the arviz package to Colab? It is needed for plotting traceplots of pymc3, currently I am having to download pymc3 traces from drive back to local and plot there.

@HinLeung622 Thanks for reporting the issue. We've upgraded both pymc3 and pandas since it was filed and the bug no longer occurs.

We have additional upgrades of these and other packages planned in the near future. Stay tuned.
