Common Issues

Conda Environment

TTS WebUI by default uses a conda environment (when installed using start_tts_webui). This environment can be accessed by using the file at ./tools/conda_env_cmd.bat for Windows or ./tools/conda_env_bash.sh for Linux & Mac.

ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

This error happens when the pip package 'numpy' accidentally gets upgraded beyond version 1.x to 2.x. Although there are safeguards, this still happens. The fix is to do pip install numpy<2 in the conda environment (or venv) of the TTS WebUI.
