PYMC3 Reports "WARNING (theano.tensor.blas): Using NumPy C-API based implementation for BLAS functions"

When I run PYMC3 on Ubuntu 16.04 LTS, I encounter an error,

WARNING (theano.tensor.blas): Using NumPy C-API based implementation for BLAS functions.

This went after I installed,

sudo apt-get install libblas-dev liblapack-dev libatlas-base-dev gfortran  

I also notice that the problem persists when I only install the mkl and mkl-service as suggested in the theano documentation and the discussion here.
