DepreciationWarning: tmva102_Testing.py HELP!

I’m currently trying to run tmva102_testing.py and I’m having trouble. Specifically, I’m getting this error:

DeprecationWarning: The ‘reorder’ parameter has been deprecated in version 0.20 and will be removed in 0.22. It is recommended not to set ‘reorder’ and ensure that x is monotonic increasing or monotonic decreasing.
DeprecationWarning)

Then, it opens the python launcher, closes it, and I don’t get to see anything. I believe the output is supposed to be a graph? How can I override this warning and get what I’m looking for? Thanks!

I think @moneta can help you.
