Issue with xFormers Loading C++/CUDA Extensions - Deforum Stable Diffusion (v0.7.1)

I'm encountering the following error when trying to use xFormers with Deforum Stable Diffusion (v0.7.1):

```
xFormers can't load C++/CUDA extensions. xFormers was built for:
PyTorch 2.2.0+cu121 with CUDA 1201 (you have 2.3.0+cu121)
Python 3.10.13 (you have 3.10.12)
```

It seems that there is a mismatch between the version of PyTorch and Python that xFormers was built for and the versions installed on my system. Specifically:

- xFormers was built for **PyTorch 2.2.0+cu121** with **CUDA 1201**, but I have **PyTorch 2.3.0+cu121**.
- xFormers was also built for **Python 3.10.13**, while I have **Python 3.10.12**.

Has anyone else encountered this issue? If so, any guidance on how to resolve this or suggestions on how to get xFormers working with these versions would be greatly appreciated.

The issue identifies no repository files, tests, or entry points to inspect. Begin by reproducing the reported xFormers loading error with the stated Python and PyTorch versions; the issue would be complete only once a repository-level fix or documented supported-version path is defined and verified.
