Hey there, PyTorch developers! Welcome back to another episode of the PyTorch podcast. I'm your host, and I'm genuinely excited to dive into what happened in the codebase on February 2nd, 2026. Grab your favorite beverage because we've got some really interesting stuff to talk about today.
Now, here's something a bit unusual - we had zero merged pull requests today, but don't let that fool you. Sometimes the most interesting development days are the ones filled with thoughtful commits and careful improvements. We had 12 commits that tell a fascinating story of optimization, cleanup, and expanding…
Let me start with what I think is the most exciting news. Wei Feng made a fantastic change to FSDP2 by removing those GPU-only test restrictions. Remember when FSDP2 gained CPU support? Well, now the tests actually reflect that capability! It's one of those changes that seems small but represents a huge step forward…
Speaking of performance improvements, CaoE delivered something really special for the Inductor CPP backend. They tackled a tricky problem with MKLDNN convolution layout propagation that was causing some serious performance headaches. Picture this - you're running a model with…
