How can I run Mozilla TTS/Coqui TTS training with CUDA on a Windows system? - text-to-speech

Question

I have a machine with a Quadro P5000 graphics card, running Windows 10. I'd like to train a TTS voice on this system. What do I need to install to make this work?

Answer 1

Here's what to install/do:
Download and install Python 3.8 (not 3.9+) for Windows. During the installation, ensure that you:
Opt to install it for all users.
Opt to add Python to the PATH.
Download and install CUDA Toolkit 10.1 (not 11.0+).
Download "cuDNN v7.6.5 (November 5th, 2019), for CUDA 10.1" (not cuDNN v8+), extract it, and then copy what's inside the cuda folder into C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1.
Download the latest 64-bit version of eSpeak NG (no version constraints :-) ).
Download the latest 64-bit version of Git for Windows (no version constraints :-) ).
Open a PowerShell prompt to a folder where you'd like to install Coqui TTS.
Run git clone https://github.com/coqui-ai/TTS.git.
Run cd TTS.
Run python -m venv ..
Run .\Scripts\pip install -e ..
Run the following command (this differs from the command you get from the PyTorch website because of a known issue):
.\Scripts\pip install torch==1.8.0+cu101 torchvision==0.9.0+cu101 torchaudio===0.8.0 -f https://download.pytorch.org/whl/torch_stable.html
Put the following into a script called "test_cuda.py" in the TTS folder:
import torch
x = torch.rand(5, 3)
print(x)
print(torch.cuda.is_available())
Run the script via .\Scripts\python ./test_cuda.py and confirm the output looks like this (the first part should have just random numbers, but the last line must read True; if it does not, CUDA is not installed properly):
tensor([[0.2141, 0.7808, 0.9298],
[0.3107, 0.8569, 0.9562],
[0.2878, 0.7515, 0.5547],
[0.5007, 0.6904, 0.4136],
[0.2443, 0.4158, 0.4245]])
True
Put the following into a script called "train.bat" in the TTS folder, and then customize it for your configuration file:
set PYTHONIOENCODING=UTF-8
set PYTHONLEGACYWINDOWSSTDIO=UTF-8
set PHONEMIZER_ESPEAK_PATH=C:/Program Files/eSpeak NG/espeak-ng.exe
.\Scripts\python.exe ./TTS/bin/train_tacotron.py --config_path "C:/path/to/your/config.json"
Run the script via .\train.bat.
If you are using a different model than Tacotron or need to pass other parameters into the training script, feel free to further customize train.bat.
