Can't load local sever

[daokham2005-hue]

So first I download the project

1. So I use qwen3:14B and use whisper small set up kobold
2. I go to in Yaml and remove all the cloud and keep the local like kobold, melotts (remove kobold tts)
3. Then I download:
   https://github.com/manhcuong02/MeloTTS_Vietnamese
4. And then I put it in model/melotts
5. Next up I go to this and download in file pretrain (download one file with the config): https://huggingface.co/nmcuong/MeloTTS-Vietnamese/tree/main
6. then open power shell to download pip install underthesea, segments
7. And change a bit in the test_infer.ipynb like the Run Inference tell at step 3
   then run test with 2 language EN and VI
   code for En:
   python -c "from melo.api import TTS; model=TTS(language='EN', device='cuda'); speaker_ids=model.hps.data.spk2id; model.tts_to_file('Hello, this is a MeloTTS test.', speaker_ids['EN-Default'], 'test.wav'); print('done')"
   code for vn:
   python -c "from melo.api import TTS; model=TTS(language='VI', config_path='models/config.json', ckpt_path='models/G_463000.pth', device='cuda'); model.tts_to_file('Xin chào bạn. Đây là đoạn kiểm tra tiếng Việt.', 0, r'D:\jaison-core-2.2.1\models\melotts\MeloTTS_Vietnamese\vi_test.wav'); print('DONE')"
   P/s: it might miss some model so you need to download some for it to run
8. Then I move both of it to the melotts-vietnamese and make a new folder for it
9. After that I download RVC and put it in model/rvc
10. then set up on env-plate to env and do like what readme tell
11. Then download ffmpeg like the readme
12. And finally start with python ./src/main.py --config=example
    But it end up like this
    PS D:\jaison-core-2.2.1> python ./src/main.py --config=example

Can you please share your melotts config used by this project. Should look like the following:

- role: tts
  id: melo
  config_filepath: "E:\\projects\\project_jaison\\jaison-core\\models\\melotts\\config.json"
  model_filepath: "E:\\projects\\project_jaison\\jaison-core\\models\\melotts\\G_463000.pth"
  speaker_id: VI-default
  device: cuda
  language: VI
  sdp_ratio: 0.8
  noise_scale: 0.6
  noise_scale_w: 0.8
  speed: 1.0

Note to install MeloTTS_Vietnamese, you need to actually install it, not just copy the code into model/melotts. To do this, run the following after you set everything else up: pip install melotts@git+https://github.com/manhcuong02/MeloTTS_Vietnamese.git. This should actually install the vietnamese version you're using.

I had problems with it after that, though, and you will need to go to where it's installed and add a file. To find where to add this file, run the server once, and it should fail with a message like FileNotFoundError: [Errno 2] No such file or directory: 'E:\\projects\\project_jaison\\jaison-core\\.venv\\lib\\site-packages\\melo\\text\\..\\configs/config.json'. Go to the folder <whatever comes before>/lib/site-packages/melo/text and create a folder called configs. In this folder, copy the config.json you downloaded from https://huggingface.co/nmcuong/MeloTTS-Vietnamese/tree/main. Everything else is as normal.

well I hadn't fill in the config filepath and the model filepath yet. Let me redo everything just to make sure I not make any mistake
