The Importance of Virtual Environments
Using a virtual environment is crucial to avoid conflicts between IndexTTS2 dependencies and other existing tools on your computer. It acts as a 'container' that isolates all packages.
DeepSpeed Installation Issues on Windows
The DeepSpeed library often faces installation issues on Windows operating systems. If the installation process fails at this stage, you can usually ignore it, and IndexTTS2 should still function correctly.
Case-Sensitivity Tip
When activating the virtual environment, ensure you spell the 'Scripts' folder with a capital 'S' because certain file systems may be case-sensitive.
Step by Step
How to Clone the IndexTTS2 Repository
- Choose a folder location on your computer (e.g., Desktop).
- Click on the address bar at the top of the folder.
- Type 'cmd' and press Enter to open the Command Prompt directly at that location.
- Copy and paste the 'git clone' command for the IndexTTS2 repository into the Command Prompt.
- Press Enter and wait for the cloning process to complete.
- Verify that the 'index-tts' folder has appeared in your chosen location and contains all the files from GitHub.
Setting Up a Virtual Environment Using 'uv'
- Type the command 'pip install uv' in the Command Prompt to install the 'uv' package globally.
- Navigate into the cloned 'index-tts' folder.
- Open the Command Prompt inside that folder.
- Run the command to create a virtual environment (e.g., 'uv venv').
- Confirm that the '.venv' folder has been created within the directory.
- Activate the virtual environment by typing '.venv\Scripts\activate' (Ensure the 'S' in 'Scripts' is capitalized).
- Wait until the terminal shows that the virtual environment is active before proceeding with the installation.
Installing Dependencies & Downloading AI Models
- Run the dependency installation command using 'uv' (such as 'uv pip install').
- Allow the system to download and install all required packages (this process may take some time depending on your internet speed).
- If you encounter a 'DeepSpeed' related error on Windows, you can skip that step as it is notoriously difficult to install on Windows.
- Use the Hugging Face CLI by entering the model download command provided for IndexTTS2.
- Wait for all model files to finish downloading completely without any error messages.
