When printing out on screen:

Version --> ommprotocol v0.1.3+0.g24fde72.dirty

I can't reproduce this bug with Python 2.7 nor Python 3.5. Can you provide more details on that, please? Which Python version are you using? Anyway, try with latest master (git pull should do).

[danielSoler93]

Same issue with latests master.

Let me know if you need anything else.

[jaimergp]

Nah, nothing else. Python 2.x does not support float or int division for timedeltas. I'll fix this (possible workaround here) and report back.

[jaimergp]

Can you please create a .py file and run the attached code? It should print 245 to stdout.

#!/usr/bin/env python

from __future__ import print_function
from datetime import datetime
from time import sleep

t0 = datetime.now()
sleep(5)
total = 1500
steps = 30
time = datetime.now() - t0
delta = (total - steps)*time/steps
print(delta.seconds)

[danielSoler93]

Runned on the same env as before with python and pychimera commands and everything works fine

[jaimergp]

So...? Does that mean it is magically fixed?

[danielSoler93]

It is working on python pychimera and IDLE of chimera but when executing file and importing from eggs is not working...
