Github user ambauma commented on a diff in the pull request: https://github.com/apache/spark/pull/19528#discussion_r146080089 --- 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 -- I had to apply this to get past a python unit test failure. My assumption is that the NewSparkPullRequestBuilder is on a different version of numpy than when the Spark 1.6 branch was last built. The current python unit test failure looks like it has to do with a novel version of SciPy.
