Hi everyone, I would like to ask a question about an issue that we faced regarding profiling memory usage:
We have implemented a custom memory profiler using `PyMem_GetAllocator/PyMem_SetAllocator` APIs like `tracemalloc`. Right now, we are facing an issue with numpy: numpy seems to have its own memory allocator and they use `PyTraceMalloc_Track` APIs to notify tracemalloc about the allocation. A simple search on GitHub reveals there are more projects using this approach: https://github.com/search?q=PyTraceMalloc_Track&type=code which is fine. I believe it is common to use custom memory allocators for scientific computation which makes perfect sense. However, I would have expected to have at least some form of `PyMem_NotifyAllocator` type of API instead of a one that is specific to `tracemalloc`? I might be missing some context here. WDYT?
