Hello,
I am coming over from using the base tortoise-tts to this repository and was brave enough to install on the Anaconda Windows environment. I understand that building/installing these tools in windows feels like a "hack" -- but I've got a GTX 1660 with 6 GB VRAM.
Was able to get through a number of issues with installing this in Anaconda. But there are a few errors in gradio and places that I had to comment out code in order to prevent faults, untll I downgraded to Gradio 3.23.
Now it is really odd - I was having a problem with seeing 'NoneType' is not iterable when I was in training, and trying to prepare dataset under the training tab. transcribing
This happened when I set "Validation Text Length Threshold" and "Validation Audio Length Treshold" to "0" each. I just realized as I was trying to re-create the error, I used the default values of 12 and 1 respectively, it worked. Seemed like the documentation said that setting to "0" would ignore those values.
So I guess the error is using 0 for both of those doesn't seem to work like using the default values.
For anyone reading this trying to fight through installing on Anaconda, my biggest issue when installing was that GPU CUDA was not enabled. I was able to tell via:
python -c "import torch; print(torch.cuda.is_available());torch.zeros(1).cuda()"
I basically had to uninstall and then re-install via below command
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu117
I also ran into the error with the model being the corrupted (the 1.7 Gb one):
RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory
I re-downloaded it from I guess it was HuggingFace (I think it is the tortoise-tts v2 model).
I was also getting an issue with below:
Task exception was never retrieved
future: <Task finished name='64mkxjl8bqn_46' coro=<Queue.process_events() done, defined at D:\applications\ai-voice-cloning\ai-voice-cloning\venv\lib\site-packages\gradio\queueing.py:343> exception=1 validation error for PredictBody

Traceback (most recent call last):

Got through that error by using a different version of pydantic:
pip uninstall pydantic
pip uninstall pydantic-core
pip install pydantic==1.10.11
pip install pydantic-core
I find the base tortoise-tts to be legendary and mrq - you are a legend for making the training/fine tuning widely available. I look forward to understanding the training/finetuning process.
Nope. For some reason I just tried to train again... and I did leave it at the defaults. I got the same error.
When I am in the "Training Tab" and hit "Prepare Dataset"

This appears to be a whisper error.
Will comment with a solution once I work through this.
Very easy fix.
pip uninstall whisper
pip install openai-whisper
I feel like I may have complicated things by using the tortoise-tts virtual environment that was working previously, so maybe I didn't have the correct version of whisper installed?
edited to say: If you are having errors like this, you didn't install properly! I re-installed properly from scratch and everything is now functioning as expected!
