[Numpy-discussion] py2/py3 pickling

2015-08-23 Thread Chris Laumann
Hi all- Is there documentation about the limits and workarounds for py2/py3 pickle/np.save/load compatibility? I haven't found anything except developer bug tracking discussions (eg. #4879 in github numpy). The kinds of errors you get can be really obscure when save/loading complicated

indistinguishable types for 2d arrays with slightly different semantics for a small subset of operations is terrible.

is more complicated than can be expressed as left-right or right-left (because some matrices might be diagonal, CSR or CSC), which is why the preference is only weak. I don’t see a down-side in the use-case that it is actually associative (as in matrix-matrix-vector).  Best, Chris --  Chris Laumann

Good morning all-- didn't realize this would generate quite such a buzz. To answer a direct question, I'm using the github master. A few thoughts (from a fairly heavy numpy user for numerical simulations and analysis): The current behavior is confusing and (as far as i can tell) undocumented.
