2010-02-28 Thread Gael Varoquaux
Hi, I need to have list of objects that contain ndarrays to be sorted. The reason that I want them sorted is that these list are populated in an arbitrary order, but there order really doesn't matter, and I am trying to make it reproducible for debugging and hashing. The problem is that ndarrays
