Error when running GRNBoost2

[rjb67]

I am running GRNBoost2 as part of pySCENIC and encountered an error that I have not seen posts about previously. Here is what the console returns when I run it:

preparing dask client

parsing input

creating dask graph

6 partitions

computing dask graph

Any help would be appreciated.
