Probably you have to set the following environment variables.

export OPENBLAS_NUM_THREADS=1 # If you are using OpenBLAS
export MKL_NUM_THREADS=1 # If you are using MKL
export NUMEXPR_NUM_THREADS=1
export OMP_NUM_THREADS=1

Although I don’t know if you using MKL or OpenBLAS. By the way, yo have to be very careful, the values you get from pymc3 differ a lot from pymc.
