Hey there, PyTorch developers! Welcome back to another episode of our daily deep dive into the world's favorite deep learning framework. I'm your host, and wow, do we have an exciting day to unpack together. January 26th brought us thirteen solid commits that really showcase the breadth of work happening across the…
Let's start with what I think is the most exciting development today - xinan.lin just landed part three of a four-part series that's bringing XPU static launcher support to PyTorch. This isn't just any ordinary feature addition - we're talking about 583 lines of new C++ code that's opening up entirely new hardware…
Speaking of hardware support, Isalia20 gave us a wonderful gift for MPS users today - geometric distribution implementation. This might sound like a small addition, but if you're doing probabilistic modeling or sampling work on Apple Silicon, this is going to make your life so much easier. It's these kinds of…
Now, here's something that got me really excited from a testing perspective - Pian Pawakapan introduced a brand new test file called `test_ops_unbacked.py`. This is huge for anyone working with dynamic shapes! They've created a comprehensive test suite…
