Seems like it, that's weird. Col2 appears to work fine, but col1 is both wrong and for some reason a float. Can you post the underlying ordinal encoder mapping?
from category_encoders.
[{'col': 'col1', 'mapping': [('a', 0), ('b', 1), ('c', 2)]}, {'col': 'col2', 'mapping': [('d', 0), ('e', 1), ('f', 2)]}]
col1_0 col1_1 col2_0 col2_1
0 0.0 0.0 0 0
1 0.0 1.0 0 1
2 0.0 0.0 1 0
I think bug is in the function def basen_encode(self, X_in, cols=None)
in basen.py
https://github.com/scikit-learn-contrib/categorical-encoding/blob/56d01334de5b1c45f5ddb600f587c86bfa67d9c0/category_encoders/basen.py#L238

Yeah, the ordinal mapping looks fine, I'll have to take a closer look at BaseN and write some tests for this example when I get a chance. Thanks for the heads up.
