Python Pandas - Missing required dependencies ['numpy'] 1

Since yesterday I've had this error when I try to import packages on anaconda :

ImportError: Missing required dependencies ['numpy']

I have tried un-installing Anaconda and Python, switching to Python 2.7 but nothing works it's still the same error, here is the code I get :

Any help is really appreciated thanks !

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.

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 don't install it automatically for whatever reason.

What happens if you try to import numpy?

Have you tried'

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