This might help someone in the future, so a note that will (hopefully) be updated in the future.
Using dask.distributed as installed via conda didn’t work for me:
RuntimeError: The current Numpy installation (‘/Users/jgh/psi4conda/lib/python3.6/site-packages/numpy/init.py’) fails to pass simple sanity checks. This can be caused for example by incorrect BLAS library being linked in.
I’ve not yet found a solution for this, but things to try include building dask.distributed from source and investigating other distributed libs.
