Where can I find the .pt files needed for testing?

Hi,
I want to run the test script [bytelatent/test_blt.py](https://github.com/facebookresearch/blt/blob/main/bytelatent/test_blt.py), but it looks like there are no .pt files in the repo. Are these files available somewhere, or is there a way to generate them? Any help or instructions would be appreciated. Thanks!

Start with bytelatent/test_blt.py and inspect how it loads the missing .pt files. Trace whether the artifacts have a documented source or generation path, then identify the appropriate documentation location and record instructions that let a fresh checkout run the test successfully.
