Hi,
There is an error when running python-tests.el, I pasted on the tail
of this mail.

The error is caused by the test case trying testing the functions with
ipython but its subroutine didn't use the ipython as interpreter.

Changing the test interpreter will fix the issue, I attached the patch.

Please help apply the change. Thanks.


Test case error message:
