Pytorch profiler lightning This even continues after training, probably while the profiler data is processed. This class should be used when you don’t want the (small) overhead of profiling. It works perfectly with pytorch, but the problem is I have to use pytorch lightning and if I put this in my training step, it just doesn't create the log file nor does it create an entry for profiler. The objective is to target the execution steps that are the most costly in time and/or .
