TypeError: 'float' object cannot be interpreted as an integer

The final Type Error is coming from cols = MV2.reshape(cols, (len(cols) / 3, 3)) part in the above message, where Python 2 returns integer while Python 3 returns float.

For example in Python 2:

>>> 3/2
1

But in Python 3:

>>> 3/2
1.5

And given float number cannot be used for the reshape of MV2.

@doutriaux1 any chance to fix this? @gleckler1 you may experience same error when you update your pmp to most recent.

Issue moved to PMP.
PCMDI/pcmdi_metrics#581

[doutriaux1]

@lee1043 you got one of the few that escaped us! Fixing right away in pmp

@doutriaux1 good to know. Yay, gotcha! :)
