Issue with Basic Usage Code

[effy46]

Here is the code I am using:

import ChatTTS
import torch
import torchaudio


chat = ChatTTS.Chat()
chat.load(compile=False) # Set to True for better performance

texts = ["All set. Lets go", "Lets get started,drive safe"]

wavs = chat.infer(texts)

for i in range(len(wavs)):
    """
    In some versions of torchaudio, the first line works but in other versions, so does the second line.
    """
    try:
        torchaudio.save(f"basic_output{i}.wav", torch.from_numpy(wavs[i]).unsqueeze(0), 24000)
    except:
        torchaudio.save(f"basic_output{i}.wav", torch.from_numpy(wavs[i]), 24000)

I received below error:
