Weird error when 'OP' argument is set

[freicaneca]

When calling ELM.train(data, labels, "CV", "OP", 'c', k=5) on the data and labels attached, I get the following error:

Traceback (most recent call last):
File "parameter_analysis_elm.py", line 81, in

File "/usr/local/lib/python3.5/dist-packages/hpelm/elm.py", line 198, in train
e = train_cv(self, X, T, k)

File "/usr/local/lib/python3.5/dist-packages/hpelm/modules/mrsr2.py", line 66, in mrsr2
nonrank.remove(j_current)
AttributeError: 'range' object has no attribute 'remove'

I couldn't figure out how to solve it, unless by removing "OP" flag. The flag works for another data file, much smaller than this one.

I've encountered the same problem actually. I've issued a pull request which seems to have fixed that.
The problem is due to the fact that in Python 3 the range function don't return a list but a range type.
