error in train.py line 160 #10

I am training roadtracer on some new dataset (East African cities), and I got this error in the train.py file:

Traceback (most recent call last): File "train.py", line 160, in raise Exception('last set has only {} paths, but PARALLEL_PATHS={}'.format(end_idx - start_idx, PARALLEL_PATHS)) Exception: last set has only -948.0 paths, but PARALLEL_PATHS=1024

I followed the instruction on the github page, still get this error

Sorry for the slow reply. If you are using python 3 that might be the cause, on this line below the code assumes it will truncate the division:

Using python 2 would be easiest solution if that is possible, otherwise I think there are several changes you'd need to make.

Thank you for the reply. I will try fixing that to see if it will run.
