Failed to load the extension "coqui_tts"

[TerryZWZ]

Describe the bug

I am getting an error when starting start_windows.bat with the coqui_tts extension enabled. I have already tried redownloading a fresh text-generation-webui, and testing TTS from the command line which does produce .wav files normally.

The error is RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory.

What steps do I need to do in order to fix this error?

Is there an existing issue for this?

Reproduction

I followed all the steps from the link below, using the one-click installer on Windows 11:

I notice you are on a B drive, which is normally a reserved, well, kind of a reserved drive letter for very historic DOS purposes (back from 1980's era).

I'm assuming therefore that the B drive is a virtual drive of some kind? Rather than a physical disk partition.

If so, that may well be causing some kind of issue. Maybe try putting at least the install on your C, D, E etc drive...

You can still have your models folder on your B drive by editing the CMD_FLAGS.txt file and using --model path
e.g. --model B:\AI\models (or wherever your models folder is)
