Scientific View: Bug: PY-33670: Scientific view doesn't support Python < 3. Our sparse tensor format permits uncoalesced sparse tensors, where there may be duplicate coordinates in the indices; in this case, the interpretation is that the value at that index is the sum of all duplicate value entries. When we work with Multiprocessing,at first we create. Active 1 year, 5 months ago. Uncoalesced tensors permit us to implement certain operators more efficiently. If the same operation object is passed in again, then the cursor can optimize its behavior. I have wanted to try the multiprocessing module out for some time, and now have a consulting project that will really benefit. I want to fit many distributions with scipy and would like to use some sort of multiprocessing for this. Starting a background thread for email being sent is much less resource intensive than starting a brand new process, so I'm going to go with that approach:. Side effects.
