@RondeauG The cell that appears to be failing is one that calls an instance of dask.ProgressBar:

I know that this is a major issue when running notebooks, as this asynchronous process does not necessarily block the execution of the next cell. Though the fact that this is failing within the cell tells me that it might simply be dask related. You might need to supply some kwargs to not use dask?

Ok, I'll look into it.

@RondeauG Well done! I think this is good to merge!
