The code has few comments but gotta love when you can tell someone was having fun!

I’m honestly impressed that a pure python implementation can beat out vLLM and SGLang. Granted they lean on FlashInfer, and of course torch.compile has gotten incredibly powerful in the last few years. Though dynamic shapes have still been a huge thorn in my side, I’ll need to look closer at how they pulled it off…

Hi! I work on dynamic shapes in pytorch and would love to hear more about the challenges you’ve run into. We’re always looking to improve the experience, so if you’re open to chatting, feel free to DM me on Twitter (@bobrenjc93) or email me at [e-mail].

since you work on pytorch, what would you say is the best place to ask questions about general usage, trouble shooting? I’ve been struggling with a, what I would consider, a simple torchrun elastic training example, and haven’t found any good resources online. I’ve been spelunking through pytorch but have a feeling a little back and forth with someone familiar with these features would immensely clear things up.

PyTorch Dev Discuss is a fantastic forum where many core devs actively participate and answer questions: https://dev-discuss.pytorch.org

In addition to Dev Discuss, a number of core contributors are also active on Twitter. Two particularly helpful and prolific voices are @ezyang and @cHHillee.

Finally, don’t overlook GitHub issues—they’re a surprisingly effective way to start conversations. If you’ve found a bug or have ideas on how to improve the APIs, opening an issue is always welcome.

There's also the slack but you gotta know someone to get on that ;)

I mean, vllm and sglang are both "pure python" essentially as well. But yeah, in ML you rarely require C++ to get good performance for most of the systems people are writing.
