json problem in api.py

[matthewboman]

When I try to run the program, I get this error:

RuntimeError: module compiled against API version 0xa but this version of numpy is 0x9
Traceback (most recent call last):
  File "api.py", line 33, in <module>

    from matplotlib._path import (affine_transform, count_bboxes_overlapping_bbox,
ImportError: numpy.core.multiarray failed to import

I then tried to update numpy to the most recent version, which leads to this error:

    Traceback (most recent call last):

    raise ArgumentError(action, message % conflict_string)
argparse.ArgumentError: argument --plot-file: conflicting option string(s): --plot-file

I tried it using my code, and then I tried it using the code on here, but either way I get the same issue.

Looks like you might have added the "--plot-file" option twice via add_argument method.
See the same error explained here: https://docs.python.org/2/library/argparse.html#conflict-handler
