Hi All, This is to note that gh-6592 <https://github.com/numpy/numpy/pull/6592> proposes to accelerate a planned future change to array_split. In Numpy < 1.9 empty arrays resulting from split always had dimension (0,),regardless of the dimensions of the other arrays in the result. In Numpy 1.9 a FutureWarning was raised saying that that would change and at some point empty arrays would have dimensions consistent with the other arrays in the result. However, there was a bug in the condition for raising that warning and empty arrays that were not the last of the returned arrays already had consistent dimensions. As a result, 1.9 was half way to the future but not quite there. That bug was fixed in 1.10.0, but some folks were already relying on the future behavior and opened a bug report on 1.10, see gh-6575 <https://github.com/numpy/numpy/issues/6575>. This left us in a sticky position. The decision has been made to revert the bug fix in 1.10 so that things remain as they were in 1.9, and move completely to consistent dimensions in 1.11. The move is a bit accelerated but seems the most graceful way out of the morass.
Thoughts? Chuck
