division by 0 in eta.py

[Iulian7]

Hello,

I am using the progress bar to report progress on some long running task. Sometime I get a division by 0 exception in eta.py at line 155:

pearson_r = sum_xy / sqrt(sum_sq_v_x * sum_sq_v_y)

This does not happen all the time, but it does happen quite frequently. Sometimes the numerator is incremented by 0, sometime by some thousands.

Is this a known bug?

Thanks,
Iulian

I'm also getting this error in the same spot. I'm guarding against setting the bar numerator value to 0 but it's still happening. It also happens more frequently for me on long running processes.

I could fix it for me by adding

if self._timing_data and numerator == self._timing_data[-1][1]:
    return

to eta.py line 117.
