AttributeError: 'HigherOrderOperator' object has no attribute 'py_functionalize_impl'

I've followed the steps outlined https://pytorch.org/executorch/stable/getting-started-setup.html
But after running

python3 -m examples.portable.scripts.export --model_name="add"

I am getting the following error

    mod_name, mod_spec, code = _get_module_details(mod_name, _Error)

Hey @huydhn

It looks like it is the same issue as #1413

I tried installing pip install --force-reinstall --pre torch=="dev20231010" -i https://download.pytorch.org/whl/nightly/cpu

but it is not installing

Let me take a look, the files are still there on S3, but they are gone from the index. The code was moved around recently in pytorch/test-infra#4879, so may be it causes a regression

[huydhn]

This should be fixed by pytorch/test-infra#4900

[AlexRibard]

Duplicate of #1662 I'd say.
With conda all is good. It's really pip which messes up dependencies

[huydhn]

The files are back in the index now https://download.pytorch.org/whl/nightly/torch/ and pip install --force-reinstall --pre torch=="2.2.0.dev20231010" -i https://download.pytorch.org/whl/nightly/cpu works as expected.

Thanks @huydhn

I just went through the setup script in https://pytorch.org/executorch/stable/getting-started-setup.html from beginning to end.

Works for me now.

Thanks @AlexRibard for reporting. This was an actual bug on our side where torch=="2.2.0.dev20231010" (that stable branch, v0.1.0, uses) doesn't exist in the nightly index. Huy just updated it.
