This problem appears after that branch "8235a46711ef738387ec17604a7e73f674930719"

Can you paste your code? I'm also using mps but cannot reproduce your problem.

I did not modify the code, only used example/cmd/run.py

Can you paste it?

Seems all right.

I fixed the issue on my PC by adding the following code:

        del_all(logits_warpers)
        del_all(logits_processors)

Code Localtion: ChatTTS/core.py: 571
