## Requirements

This repository is tested on Ubuntu 20.04 with a GPU Titan V.

- Python 3.8+
- Cuda 11.0+
- CuDNN 8+
- NCCL 2+ (for distributed multi-gpu training)
- libsndfile (you can install via `sudo apt install libsndfile-dev` in ubuntu)
- jq (you can install via `sudo apt install jq` in ubuntu)
- sox (you can install via `sudo apt install sox` in ubuntu)

Different cuda version should be working but not explicitly tested.  
All of the codes are tested on Pytorch 1.8.1, 1.9, 1.10.2, 1.11.0, 1.12.1, 1.13.1, 2.0.1 and 2.1.0.

# If you want to use distributed training, please install

---

# command to install apex.
$ make apex
```

Note that we specify cuda version used to compile pytorch wheel.  
If you want to use different cuda version, please check `tools/Makefile` to change the pytorch wheel to be installed.

---

# If not, please install via pip
$ pip install parallel_wavegan

---

# Please install this repository in ESPnet conda (or virtualenv) environment
$ . ./path.sh && pip install -U parallel_wavegan
