I wana to measure the point in time for each tensor in training. For exmaple, when i train a sample network in python api, i want to get the point in time for each tensor. I have inserted some “chrono” time api in “relu” func in Actiovation.cpp (I have not inserted the code into backward func part), but it is too intricate to insert some code in each implement file. Can it be reliazed by controled by a global (singleton pattern) time counter in impl file or somewher? I am not realy sure about this part code .
