Silly question, what’s the lowest spec hardware this will run ?
Listing the issues in case it helps anyone:
- It doesn't work with Python 3.13, luckily `uv` makes it easy to build a venv with 3.12
- It said numpy 1.26.4 doesn't exist. It definitely does, but `uv pip` was searching for it on the pytorch repo. I passed an `--index-strategy` flag so it would check other repos. This could just be a bug in uv, but when I see "numpy 1.26.4 doesn't exist" and numpy is currently on 2.x, my brain starts to cramp up.
- The `pip install chatterbox-tts` version has a bug in CPU-only mode, so I cloned the Git repo
- The version at the tip of main requires `protobuf-compiler` installed on Debian
- I got a weird CMake error that I can't decipher. I think maybe it's complaining that the Python dev headers are not installed. Why would they be, I'm trying to do inference, not compile Python...
I know anger isn't productive but this is my experience almost any time I'm running Somebody Else's Python Project. Hit an issue, back up, hit another issue, back up, after an hour it still doesn't run.

But if the model is any good someone will probably find a way to optimize it to run on even less.
Edit: Got it running on an old Nvidia 2060, I'm seeing ~5 GB VRAM peak.
So out of the box it seems quite beefy consumer hardware will be needed for it to perform reasonably. However it seems like there's significant potential for improvements, though I'm no expert.
If something can be run for free but it's cheaper to rent, it voids the DIY aspect of it.
