Python : RuntimeWarning: overflow encountered

Question

When i run pyOpenTld i get RuntimeWarning: overflow encountered in int_scalars from this module. Why is this happening?

Warning (from warnings module):
    File "D:\Python27\lib\pyOpenTLD\TLD\IntegralImage.py", line 34
        op[cols * j + i] = A + B - C + value
RuntimeWarning: overflow encountered in int_scalars

Thanks! ras

I think you are trying to create an int32 which is outside the allowed range. As per answer to SO question below, the maximum is 2**31-1.

I don't know pyOpenTld (or your code) but possibly try changing the type of A + B - C + value or cols*j+i, which might be the problem if it is part of a loop.

Also have a look at this answer which describes it quite well.

Here is more information on numpy dtypes and their allowed range.

Could you also show the code you are running that causes the problem?
