ImportError: numpy.core.multiarray failed to import when importing econ.dml

[meganfang-8451]

I've been running econ.dml's CausalForestDML. However, today when I tried to import econ.dml, I got this error: ImportError: numpy.core.multiarray failed to import

Hm. That sounds like an issue where a binary-incompatible version of numpy is being used. Could you post the output of pip list, as well as what your environment is (CPU architecture, operating system, python version)? As a stab in the dark, you might try uninstalling and then reinstalling econml via pip and see if that helps.
