Python Pandas – Missing required dependencies [numpy] 1

Python Pandas – Missing required dependencies [numpy] 1

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.

What happens if you try to import numpy?

Have you tried

pip install --upgrade numpy
pip install --upgrade pandas

I had to install this other package:

sudo apt-get install libatlas-base-dev

Seems like it is a dependency for numpy but the pip or apt-get dont install it automatically for whatever reason.
