I encountered an AttributeError when running the XTTS-API-SERVER. The error message indicates that the torch.amp module does not have an attribute GradScaler. Below is the full traceback of the error:

def _grad_clipping(self, grad_clip: float, optimizer: torch.optim.Optimizer, scaler: torch.amp.GradScaler):
AttributeError: module 'torch.amp' has no attribute 'GradScaler'
Steps to Reproduce:
Install the XTTS-API-SERVER package and its dependencies.
Import the app module from xtts_api_server.server.
Run the script.
Expected Behavior:
The server should start without any errors.
Actual Behavior:
An AttributeError is raised, indicating that torch.amp does not have the GradScaler attribute.
Environment:
OS: Ubuntu 20.04 & second try: Windows 11
Python Version: 3.10.11
XTTS-API-SERVER Version: 0.9.0
PyTorch Version: 2.1.1+cu118
Additional Information:
This error might be due to a mismatch between the PyTorch version and the usage of the GradScaler attribute in the code. In recent versions of PyTorch, GradScaler is located under torch.cuda.amp rather than torch.amp.
Potential solution: Update the import statement in trainer.py to:
