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: What is the appropriate uncompressed kernel ELF to use with dwarf2json? [ 5.19.0-42-generic #43~22.04.1-Ubuntu ], in order to create generate a custom symbols table to conduct linux memory forensics on Ubuntu 22.04? | /r/computerforensics | 2023-05-28
I need this to create generate a custom symbols table (using dwarf2json), in order to run a memory dump acquired by Ubuntu 22.04, as Ubuntu 22.04 kernel does not work anymore with volatility 2 (Issue here: volatilityfoundation/volatility#828)

Project mention: Why is it using that much ram? Is that a trojan? Is that a feature of the linux-tkg kernel? (nothing else is running in the background) | /r/linuxmasterrace | 2023-07-01
I use a script I call memtop10.sh that uses a combination of ps and ps_mem.py which you can find here: https://github.com/pixelb/ps_mem/blob/master/ps_mem.py

memorizing-transformers-pytorch
Implementation of Memorizing Transformers (ICLR 2022), attention net augmented with indexing and retrieval of memories using approximate nearest neighbors, in Pytorch
-
-
recurrent-memory-transformer-pytorch
Implementation of Recurrent Memory Transformer, Neurips 2022 paper, in Pytorch
Of course, lucidrains already has an empty repo up. So that's worth keeping an eye on.

Rust is good, but when you need a double linked list(my Theine cache package uses that a lot) everything changes. Actually I would recommend Go if you want an alternative.

gpt-voice-conversation-chatbot
Allows you to have an engaging and safely emotive spoken / CLI conversation with the AI ChatGPT / GPT-4 while giving you the option to let it remember things discussed.
-
that line of research is still going. https://github.com/lucidrains/block-recurrent-transformer-py... i think it is worth continuing research on both fronts.
