No module named 'numpy'

Sounds like you have another version of Python installed that PyScript is seeing. Easiest solution is to not use PyScript, but you may be able to fix it by re-installing/re-configuring PyScript to make sure that it points to the same location/version of your Python27

Chances are you have multiple versions of python installed, type:

which python

in your terminal, see what's the current one.

in terminal:

sudo apt-get install python-numpy
