I'm running Tensorflow 0.9.0 installed from wheel on Python 2.7 on a K40 with CUDA 7.0. The following test case attempts to minimize the mean of a vector through gradient descent. The script finds that the vectors are equal at all steps, but the means are not. I believe the vectors ...

Describe the bug Hi, The optional parameter with_mean of the StandardScaler is not respected in all cases. Notably, for simply normalizing a column vector, it is ignored and the mean is actually computed when either fit or fit_transform ...
