Retrieval-based-Voice-Conversion-WebUI IndexError: list index out of range

When clicking on Train or one Click Train, I'm getting the following error, any help would be greatly appreciated!

im the I have the same problem

It is possible to construct malicious pickle data which will execute arbitrary code during unpickling (See https://github.com/pytorch/pytorch/blob/main/SECURITY.md#untrusted-models for more details). In a future release, the default value for weights_only will be flipped to True. This limits the functions that could be executed during unpickling. Arbitrary objects will no longer be allowed to be loaded via this mode unless they are explicitly allowlisted by the user via torch.serialization.add_safe_globals. We recommend you start setting weights_only=True for any use case where you don't have full control of the loaded file. Please open an issue on GitHub for any issues related to this experimental feature. torch.load(hps.pretrainG, map_location="cpu")["model"]

Has no one helped? I am having a similar issue :

Also same issue. Installing RVC and re-editing all these scripts and downgrading/upgrading all dependencies all day has me thinking that shit is just broken lol

Traceback (most recent call last):
  File "\Retrieval-based-Voice-Conversion-WebUI\infer\modules\train\train.py", line 211, in run
    utils.latest_checkpoint_path(hps.model_dir, "D_*.pth"), net_d, optim_d
  File "\Retrieval-based-Voice-Conversion-WebUI\infer\lib\train\utils.py", line 213, in latest_checkpoint_path
    x = f_list[-1]
IndexError: list index out of range

Inside the utils.py at line 211-213, I find this:

  f_list = glob.glob(os.path.join(dir_path, regex))
    f_list.sort(key=lambda f: int("".join(filter(str.isdigit, f))))
    x = f_list[-1]

@DUMBCAT1986 I experienced the same issue

but was able to resolve it using the following steps:

Method

Redownload the models
- Navigate to the directories:
```
assets/pretrained
assets/pretrained_v2
```
- Delete all models inside these two directories.
- Redownload the correct models from the following link and place them in the corresponding directories:
  👉 Hugging Face – lj1995/VoiceConversionWebUI
Reinstall matplotlib with a specific version
```
pip install matplotlib==3.9.4
```

This worked for me. However, an “Error” message still appears in the WebUI, but I can confirm that everything functions correctly when running from the command line.
