Author: khushali9

# What does this PR do?
Removing it again after 2.13 Pytorch release. @ydshieh Also I kept version check such that it does not break for pytorch <2.13.

This [fix](https://github.com/huggingface/transformers/pull/45248) is no longer needed after issue#1 fixed by my on [Pytorch](https://github.com/pytorch/pytorch/pull/179750) 
issue#2 does not need to be fixed, as we have so many ways to avoid it. 

Basically dont use hasattr when you have already set fp32_precision generic/globally.

Fixes # (issue)

## Code Agent Policy

The Transformers repo is currently being overwhelmed by a large number of PRs and issue comments written by
code agents. These often are low-quality, or fix extremely minor issues that occur rarely or never in practice.
As a result, we're instituting a rule that **first-time contributors should not use code agents to submit PRs or issues**.
We'd also ask autonomous "OpenClaw"-like agents not to open any PRs or issues.

Issues/PRs from first-time contributors that violate this rule will probably just be closed without review, and we
might block you, especially if you open more than one or appear to be deliberately ignoring this. We especially do not
want new contributors to jump in on random issues to contribute an agent-written fix. This creates lots of noise
for reviewers and other users and will almost certainly get you blocked.

For more information, please read [`CONTRIBUTING.md`](https://github.com/huggingface/transformers/blob/main/CONTRIBUTING.md).

Comments:
@vasqu  @Rocketknight1 @ydshieh Can you please review, CI is failing because of security gate, but I have added version aware fix such that anyone using pytorch <2.13 would have no issue. Also moved those setter lines to appropriate method where it belongs (enable_tf32) and keeping is_torch_available() method clean. 

> Imo looks good to me but I think we are a few versions behind now on CI (2.11?) so I'd rather wait a bit and just nudge @ydshieh to have an eye out when we make the switch

@vasqu should not my check for torch version check take care of it ?

Sorry, a few of us are off for a bit, so it will be a bit delayed re checking here

No problem at all! Enjoy your break. No rush!

Thank you for your contribution 🤗!

## CI Security Gate — automatic approval blocked

This PR was **not** automatically approved for CI because the security gate failed.

**Possible reasons:**
- The PR touches 50 or more files — only PRs with fewer than 50 changed files are automatically approved
- A changed file is outside the allowed directories (`src/`, `tests/`, `docs/`, `utils/`), has a disallowed extension (only `.py`, `.txt`, `.md` permitted outside `tests/` and `docs/`), or is not `.md`/`.yml` inside `docs/`
- A new high-severity security issue was detected in the changed Python files (Bandit check)

See the [workflow run](https://github.com/huggingface/transformers/actions/runs/29453640558) for the exact violations.

A maintainer can review and manually approve CI if a finding is a false positive.
