Pytorch lightning advanced profiler The most commonly used profiler is the AdvancedProfiler, which provides detailed insights into your model's performance. 3. the arguments in the first snippet here: with torch. This profiler simply records the duration of actions (in seconds) and reports the mean duration of each action and the total time spent over the entire training run. Using profiler to analyze execution time¶ PyTorch profiler is enabled through the context manager and accepts a number of parameters, some of the most useful are: activities - a list of activities to profile: ProfilerActivity. prof -- < regular command here > from lightning. profile() function Jun 17, 2024 · The explanation for why this happens is here: python/cpython#110770 (comment) The AdvancedProfiler in Lightning enables multiple profilers in a nested fashion, which is apparently not supported by Python but so far was not complaining, until Python 3. A single training step (forward and backward prop) is both the typical target of performance optimizations and already rich enough to more than fill out a profiling trace, so we want to call .
