Github user ambauma commented on a diff in the pull request: https://github.com/apache/spark/pull/19528#discussion_r146084730 --- Diff: python/pyspark/mllib/classification.py --- @@ -173,7 +173,7 @@ def __init__(self, weights, intercept, numFeatures, numClasses): self._dataWithBiasSize = None self._weightsMatrix = None else: - self._dataWithBiasSize = self._coeff.size / (self._numClasses - 1) + self._dataWithBiasSize = self._coeff.size // (self._numClasses - 1) --- End diff -- The NewSparkPullRequestBuilder failed on python tests. I was only able to duplicate the failure with Python 3.4 and numpy 1.12.1, which I'm guessing is the versions that NewSparkPullRequestBuilder is using. Older and newer versions of numpy build clean either way.
