# Tacotron 2 and WaveGlow inference on TRTIS
|
||||||
|
|
||||||
|
## Setup
|
||||||
|
|
||||||
|
### Clone the repository.
|
||||||
|
```bash
|
||||||
|
git clone https://github.com/NVIDIA/DeepLearningExamples.git
|
||||||
|
cd DeepLearningExamples/PyTorch/SpeechSynthesis/Tacotron2
|
||||||
|
```
|
||||||
|
|
||||||
|
### Obtain models to be loaded in TRTIS.
|
||||||
|
|
||||||
|
We have prepared Tacotron 2 and WaveGlow models that are ready to be loaded in TRTIS,
|
||||||
|
so you don't need to train and export the models. Please follow the instructions
|
||||||
|
below to learn how to train, export --- or simply download the pretrained models.
|
||||||
|
|
||||||
|
### Obtain Tacotron 2 and WaveGlow checkpoints.
|
||||||
|
|
||||||
|
You can either download the pretrained checkpoints or train the models yourself.
|
||||||
|
|
||||||
|
#### Download pretrained checkpoints.
|
||||||
|
|
||||||
|
If you want to use a pretrained checkpoints, download them from [NGC](https://ngc.nvidia.com/catalog/models):
|
||||||
|
|
||||||
|
- [Tacotron2 checkpoint](https://ngc.nvidia.com/models/nvidia:tacotron2pyt_fp16)
|
||||||
|
- [WaveGlow checkpoint](https://ngc.nvidia.com/models/nvidia:waveglow256pyt_fp16)
|
||||||
|
|
||||||
|
|
||||||
|
#### Train Tacotron 2 and WaveGlow models.
|
||||||
|
|
||||||
|
In order to train the models, follow the QuickStart section in the `Tacotron2/README.md`
|
||||||
|
file by executing points 1-5. You have to train WaveGlow in a different way than described there. Use
|
||||||
|
the following command instead of the one given in QuickStart at point 5:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
python -m multiproc train.py -m WaveGlow -o output/ --amp-run -lr 1e-4 --epochs 2001 --wn-channels 256 -bs 12 --segment-length 16000 --weight-decay 0 --grad-clip-thresh 65504.0 --cudnn-benchmark --cudnn-enabled --log-file output/nvlog.json
|
||||||
|
```
|
||||||
|
|
||||||
|
This will train the WaveGlow model with a smaller number of residual connections
|
||||||
|
in the coupling layer networks and larger segment length. Training should take
|
||||||
|
about 100 hours on DGX-1 (8x V100 16G).
|
||||||
|
|
||||||
|
### Setup Tacotron 2 TorchScript.
|
||||||
|
|
||||||
|
First, you need to create a folder structure for the model to be loaded in TRTIS server.
|
||||||
|
Follow the Tacotron 2 Quick Start Guide (points 1-4) to start the container.
|
||||||
|
Inside the container, type:
|
||||||
|
```bash
|
||||||
|
cd /workspace/tacotron2/
|
||||||
|
python export_tacotron2_ts_config.py --amp-run
|
||||||
|
```
|
||||||
|
|
||||||
|
This will export the folder structure of the TRTIS repository and the config file of Tacotron 2.
|
||||||
|
By default, it will be found in the `trtis_repo/tacotron` folder.
|
||||||
|
|
||||||
|
Now there are two ways to proceed.
|
||||||
|
|
||||||
|
#### Download the Tacotron 2 TorchScript model.
|
||||||
|
|
||||||
|
Download the Tacotron 2 TorchScript model from:
|
||||||
|
- [Tacotron2 TorchScript](https://ngc.nvidia.com/models/nvidia:tacotron2pyt_jit_fp16)
|
||||||
|
|
||||||
|
Move the downloaded model to `trtis_repo/tacotron2/1/model.pt`
|
||||||
|
|
||||||
|
#### Export the Tacotron 2 model using TorchScript.
|
||||||
|
|
||||||
|
To export the Tacotron 2 model using TorchScript, type:
|
||||||
|
```bash
|
||||||
|
python export_tacotron2_ts.py --tacotron2 <tacotron2_checkpoint> -o trtis_repo/tacotron2/1/model.pt --amp-run
|
||||||
|
```
|
||||||
|
|
||||||
|
This will save the model as ``trtis_repo/tacotron/1/model.pt``.
|
||||||
|
|
||||||
|
### Setup WaveGlow TRT engine.
|
||||||
|
|
||||||
|
For WaveGlow, we also need to create the folder structure that will be used by the TRTIS server.
|
||||||
|
Inside the container, type:
|
||||||
|
```bash
|
||||||
|
cd /workspace/tacotron2/
|
||||||
|
python export_waveglow_trt_config.py --amp-run
|
||||||
|
```
|
||||||
|
|
||||||
|
This will export the folder structure of the TRTIS repository and the config file of Waveglow.
|
||||||
|
By default, it will be found in the `trtis_repo/waveglow` folder.
|
||||||
|
|
||||||
|
There are two ways to proceed.
|
||||||
|
|
||||||
|
#### Download the WaveGlow TRT engine.
|
||||||
|
|
||||||
|
Download the WaveGlow TRT engine from:
|
||||||
|
- [WaveGlow TRT engine](https://ngc.nvidia.com/models/nvidia:waveglow256pyt_trt_fp16)
|
||||||
|
|
||||||
|
Move the downloaded model to `trtis_repo/waveglow/1/model.plan`
|
||||||
|
|
||||||
|
#### Export the WaveGlow model to TRT.
|
||||||
|
|
||||||
|
Before exporting the model, you need to install onnx-tensorrt by typing:
|
||||||
|
```bash
|
||||||
|
cd /workspace && git clone https://github.com/onnx/onnx-tensorrt.git
|
||||||
|
cd /workspace/onnx-tensorrt/ && git submodule update --init --recursive
|
||||||
|
cd /workspace/onnx-tensorrt && mkdir -p build
|
||||||
|
cd /workspace/onnx-tensorrt/build && cmake .. -DCMAKE_CXX_FLAGS=-isystem\ /usr/local/cuda/include && make -j12 && make install
|
||||||
|
```
|
||||||
|
|
||||||
|
In order to export the model into the ONNX intermediate representation, type:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
python export_waveglow_trt.py --waveglow <waveglow_checkpoint> --wn-channels 256 --amp-run
|
||||||
|
```
|
||||||
|
|
||||||
|
This will save the model as `waveglow.onnx` (you can change its name with the flag `--output <filename>`).
|
||||||
|
|
||||||
|
With the model exported to ONNX, type the following to obtain a TRT engine and save it as `trtis_repo/waveglow/1/model.plan`:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
onnx2trt <exported_waveglow_onnx> -o trtis_repo/waveglow/1/model.plan -b 1 -w 8589934592
|
||||||
|
```
|
||||||
|
|
||||||
|
### Setup the TRTIS server.
|
||||||
|
|
||||||
|
Download the TRTIS container by typing:
|
||||||
|
```bash
|
||||||
|
docker pull nvcr.io/nvidia/tensorrtserver:19.10-py3
|
||||||
|
docker tag nvcr.io/nvidia/tensorrtserver:19.10-py3 tensorrtserver:19.10
|
||||||
|
```
|
||||||
|
|
||||||
|
### Setup the TRTIS notebook client.
|
||||||
|
|
||||||
|
Now go to the root directory of the Tacotron 2 repo, and type:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
docker build -f Dockerfile_trtis_client --network=host -t speech_ai__tts_only:demo .
|
||||||
|
```
|
||||||
|
|
||||||
|
### Run the TRTIS server.
|
||||||
|
|
||||||
|
To run the server, type in the root directory of the Tacotron 2 repo:
|
||||||
|
```bash
|
||||||
|
NV_GPU=1 nvidia-docker run -ti --ipc=host --network=host --rm -p8000:8000 -p8001:8001 -v $PWD/trtis_repo/:/models tensorrtserver:19.10 trtserver --model-store=/models --log-verbose 1
|
||||||
|
```
|
||||||
|
|
||||||
|
The flag `NV_GPU` selects the GPU the server is going to see. If we want it to see all the available GPUs, then run the above command without this flag.
|
||||||
|
By default, the model repository will be in `trtis_repo/`.
|
||||||
|
|
||||||
|
### Run the TRTIS notebook client.
|
||||||
|
|
||||||
|
Leave the server running. In another terminal, type:
|
||||||
|
```bash
|
||||||
|
docker run -it --rm --network=host --device /dev/snd:/dev/snd --device /dev/usb:/dev/usb speech_ai__tts_only:demo bash ./run_this.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
Open the URL in a browser, open `notebook.ipynb`, click play, and enjoy.
