**Summary:** This commit deprecates the following variables: ``` TORCH_VERSION_AT_LEAST_2_5 TORCH_VERSION_AT_LEAST_2_4 TORCH_VERSION_AT_LEAST_2_3 TORCH_VERSION_AT_LEAST_2_2 TORCH_VERSION_AFTER_2_5 TORCH_VERSION_AFTER_2_4 TORCH_VERSION_AFTER_2_3 TORCH_VERSION_AFTER_2_2 ``` As of this commit, the latest released version of PyTorch is 2.8, which means we can drop support for 2.5 and before since we only support 3 of the latest releases. The next commit will remove usages of all of these variables from within torchao. **Test Plan:** ``` python test/test_utils.py -k torch_version_deprecation ``` [ghstack-poisoned]

**Summary:** We gate on the PyTorch version throughout the repo. Recently PyTorch 2.8 was released, so the oldest PyTorch version we need to support is 2.6. After this commit, we assume the user is running PyTorch 2.6+, and remove all references to the following variables, which are deprecated. ``` TORCH_VERSION_AT_LEAST_2_6 TORCH_VERSION_AT_LEAST_2_5 TORCH_VERSION_AT_LEAST_2_4 TORCH_VERSION_AT_LEAST_2_3 TORCH_VERSION_AT_LEAST_2_2 TORCH_VERSION_AFTER_2_5 TORCH_VERSION_AFTER_2_4 TORCH_VERSION_AFTER_2_3 TORCH_VERSION_AFTER_2_2 ``` **Test Plan:** CI [ghstack-poisoned]

There was a problem hiding this comment.
separate PR: we want to use torch.export.export now if the min pt version support is 2.6 I think

* Deprecate old TORCH_VERSION variables **Summary:** This commit deprecates the following variables: ``` TORCH_VERSION_AT_LEAST_2_5 TORCH_VERSION_AT_LEAST_2_4 TORCH_VERSION_AT_LEAST_2_3 TORCH_VERSION_AT_LEAST_2_2 TORCH_VERSION_AFTER_2_5 TORCH_VERSION_AFTER_2_4 TORCH_VERSION_AFTER_2_3 TORCH_VERSION_AFTER_2_2 ``` As of this commit, the latest released version of PyTorch is 2.8, which means we can drop support for 2.5 and before since we only support 3 of the latest releases.
