  Memray is a memory profiler for Python

  

Project mention: Memray – A Memory Profiler for Python | news.ycombinator.com | 2024-02-10

I collected a list of profilers (also memory profilers, also specifically for Python) here: https://github.com/albertz/wiki/blob/master/profiling.md

Currently I actually need a Python memory profiler, because I want to figure out whether there is some memory leak in my application (PyTorch based training script), and where exactly (in this case, it's not a problem of GPU memory, but CPU memory).

I tried Scalene (https://github.com/plasma-umass/scalene), which seems to be powerful, but somehow the output it gives me is not useful at all? It doesn't really give me a flamegraph, or a list of the top lines with memory allocations, but instead it gives me a listing of all source code lines, and prints some (very sparse) information on each line. So I need to search through that listing now by hand to find the spots? Maybe I just don't know how to use it properly.

I tried Memray, but first ran into an issue (https://github.com/bloomberg/memray/issues/212), but after using some workaround, it worked now. I get a flamegraph out, but it doesn't really seem accurate? After a while, there don't seem to be any new memory allocations at all anymore, and I don't quite trust that this is correct.

There is also Austin (https://github.com/P403n1x87/austin), which I also wanted to try (have not yet).

Somehow this experience so far was very disappointing.

(Side node, I debugged some very strange memory allocation behavior of Python before, where all local variables were kept around after an exception, even though I made sure there is no reference anymore to the exception object, to the traceback, etc, and I even called frame.clear() for all frames to really clear it. It turns out, frame.f_locals will create another copy of all the local variables, and the exception object and all the locals in the other frame still stay alive until you access frame.f_locals again. At that point, it will sync the f_locals again with the real (fast) locals, and then it can finally free everything. It was quite annoying to find the source of this problem and to find workarounds for it. https://github.com/python/cpython/issues/113939)

Project mention: HMT: Hierarchical Memory Transformer for Long Context Language Processing | news.ycombinator.com | 2024-05-17

Code: https://github.com/OswaldHe/HMT-pytorch

This looks really interesting. I've the paper to my reading list and look forward to playing with the code. I'm curious to see what kinds of improvements we can get by agumenting Transformers and other generative language/sequence models with this and other mechanisms implementing hierarchical memory.[a]

We sure live in interesting times!

[a] In the past, I experimented a little with transformers that had access to external memory using https://github.com/lucidrains/memorizing-transformers-pytorc... and also using routed queries with https://github.com/glassroom/heinsen_routing . Both approaches seemed to work, but I never attempted to build any kind of hierarchy with those approaches.

Working on Honcho[0] a platform for personalizing LLM based applications to individual end users.

It was inspired when working on a tutoring service and realizing that the key problem of AI tutors was that they didn't know the student well enough. As we started tackling the problem other builders around us mentioned similar concerns. It's been pretty hard to explain the value to those not experiencing the same problems, but it's slowly catching on.
