Change PyTorch min version requirement

[dangkhoasdc]

What does this PR do?

As titled, If I installed the lower version (1.11+ < 2.2), I got the following issue:

>>> import transformers
Traceback (most recent call last):

I met with the same error, my environment is python==3.9, pytorch==1.13.1, pytorch-cuda==11.6, transformers==4.38.2, Is there another way to fix this problem rather than upgrade pytorch== 2.2x?

Hi, unfortunately I'm unable to reproduce your issue with torch==1.11.0. Here's the install environment I used:

- `transformers` version: 4.38.2
- Platform: Linux-6.1.58+-x86_64-with-glibc2.35
- Python version: 3.10.12
- Huggingface_hub version: 0.20.3
- Safetensors version: 0.4.2
- Accelerate version: not installed
- Accelerate config: not found
- PyTorch version (GPU?): 1.11.0+cu102 (True)
- Tensorflow version (GPU?): 2.15.0 (True)
- Flax version (CPU?/GPU?/TPU?): 0.8.2 (gpu)
- Jax version: 0.4.23
- JaxLib version: 0.4.23
- Using GPU in script?: <fill in>
- Using distributed or parallel set-up in script?: <fill in>
