LGTM Do we have similar cases in MLlib? |

To test it in jenkins might need a specified numpy version, but the code change looks ok. |

@viirya I was running python tests for pyspark-ml and pyspark-mllib and this was the only place where the python3/numpy interaction caused a test failure. There might be other places where floor int division might be preferable to float division, but if they exist they're not causing any of the tests to fail. |

…n LogisticRegressionModel ## What changes were proposed in this pull request? Fixed TypeError with python3 and numpy 1.12.1. Numpy's `reshape` no longer takes floats as arguments as of 1.12. Also, python3 uses float division for `/`, we should be using `//` to ensure that `_dataWithBiasSize` doesn't get set to a float. ## How was this patch tested? Existing tests run using python3 and numpy 1.12. Author: Bago Amirbekian <bago@databricks.com> Closes#18081 from MrBago/BF-py3floatbug.
