When does this happen?

IF On Windows, installing ChatTTS new version fails because the pynini dependency (used by nemo_text_processing) cannot be installed or used on Windows.

How others solved it

THEN Open ChatTTS/core.py, locate approximately line 143, and comment out the following 7 lines that import and use nemo_text_processing / pynini. This disables Chinese text normalization but allows the script to run on Windows without that dependency.

# In ChatTTS/core.py, comment out lines ~143-149 (the block that imports and uses nemo_text_processing/pynini)
