I just tired building PyTorch from source from this commit but I got the following messages and error:

export BUILD_CAFFE2_OPS=0
git clone https://github.com/pytorch/pytorch
cd pytorch
git checkout 3a01a45

Then I get the following messages:

warning: unable to rmdir third_party/foxi: Directory not empty

M third_party/fbgemm
M third_party/ideep
M third_party/nccl/nccl

M third_party/onnx-tensorrt
Note: checking out '3a01a45'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

git checkout -b

HEAD is now at 3a01a45... Implement IRParser. (#16987)

Then I do
git submodule update --init --recursive

and get the following messages:

I also tried with git checkout bad4442 which is a bit older than 3a01a45 but got the same error at the end.

In the past I used to compile older versions of PyTorch without an issue, but I had not done this for the past 2-3 months until today. I wonder what I should do to be able to compile an older version of PyTorch?
