just as an information for those who stuck on getting other logloss rates in their calculations.
Numerai ist calculating the logloss on the "validation"-set in the torunament test data. So simply copy the rows from this file containing "validation" in the data_type column to a new CSV.
Then you can simply make the test prediction on this file like this:
print ("Logloss : %f" % metrics.log_loss(eval_y, predictions))
eval_y are your "target" columns from the copied part of the testfile.
prediction is your predict_proba on the eval_x ( the feature columns of the same file )
