Python Pandas – Missing required dependencies [‘numpy’] 1

by

I had this same issue immediately after upgrading pandas to 0.19.2. I fixed it with the following install/uninstall sequence from the windows cmd line:

pip uninstall pandas -y
pip uninstall numpy -y
pip install pandas
pip install numpy

This also broke my matplotlib install so I uninstalled/installed that as well.

Very odd behavior for a seemingly routine upgrade.
