Run server with the below command. You can replace the path to each weight.

```
$ python3 MMVCServerSIO.py -p 18888 --https true \
    --content_vec_500 pretrain/checkpoint_best_legacy_500.pt  \
    --content_vec_500_onnx pretrain/content_vec_500.onnx \
    --content_vec_500_onnx_on true \
    --hubert_base pretrain/hubert_base.pt \
    --hubert_base_jp pretrain/rinna_hubert_base_jp.pt \
    --hubert_soft pretrain/hubert/hubert-soft-0d54a1f4.pt \

```

Also run these command.

```
pip install chardet
pip install numpy==1.24.0
```

## For Client Developer

1. Import modules and initial build

```
cd client
cd lib
npm install
npm run build:dev
cd ../demo
npm install
npm run build:dev
```

2. Enjoy developing.
