can't run example: ImportError: numpy.core.multiarray failed to import

[mikofski]

I used the conda pvpro-user install instructions in the readme, but I can't run the example:

In [1]: %run example_estimate_number_series_parallel.py

ImportError: numpy.core.multiarray failed to import

does it work for you all? I'll try pypi

[mikofski]

also, doesn't work with Python-3.6

[mikofski]

I got it to work if I put conda-forge first in the conda channels. the pvpro-user.yml didn't work. I think CVXPY needs to use NumPy with BLAS only.
