I get the following runtime error message when running the excess power module on the Jupyter Hub"

Traceback (most recent call last):
  File "test.py", line 17, in <module>

RuntimeError: Failed to find implementation of (<function _scheme_matches_base_array at 0x7f1f7fcfbaa0>) for cpu scheme.

The same packages' version is used in my personal laptop and I don't get the problem. I suspect something is wrong with the server...

The issue can be fixed by using Scipy 0.18. Later versions are introducing some incompatibilities. In order for the gdas scripts to work, one must use 0.18 or earlier versions of Scipy.
