Assert (predictions.dtypes == int).all()

I have a problem I can’t pass this assertion although all the variables are int64

assert (predictions.dtypes == int).all()

scoring.py works without problems on Linux or in the official competition runtime environment, if all variables in your submission.csv are integers.
However, scoring.py does not work on Windows and Line 28: assert (predictions.dtypes == int).all() will throw an error. Had the same problem under Windows as well. In this case, simply comment it out, if it is in your own eval code.
