[Bug] AttributeError: 'int' object has no attribute 'device'

[CrackerHax]

Describe the bug

example code gives error when saving.

To Reproduce

import os
import time
import torch
import torchaudio
from TTS.tts.configs.xtts_config import XttsConfig
from TTS.tts.models.xtts import Xtts

print("Loading model...")
config = XttsConfig()
config.load_json("/path/to/xtts/config.json")
model = Xtts.init_from_config(config)
model.load_checkpoint(config, checkpoint_dir="/path/to/xtts/", use_deepspeed=True)
model.cuda()

print("Computing speaker latents...")
gpt_cond_latent, speaker_embedding = model.get_conditioning_latents(audio_path=["reference.wav"])

print("Inference...")
t0 = time.time()
chunks = model.inference_stream(
    "It took me quite a long time to develop a voice and now that I have it I am not going to be silent.",
    "en",
    gpt_cond_latent,
    speaker_embedding
)

wav_chuncks = []
for i, chunk in enumerate(chunks):
    if i == 0:
        print(f"Time to first chunck: {time.time() - t0}")
    print(f"Received chunk {i} of audio length {chunk.shape[-1]}")
    wav_chuncks.append(chunk)
wav = torch.cat(wav_chuncks, dim=0)
torchaudio.save("xtts_streaming.wav", wav.squeeze().unsqueeze(0).cpu(), 24000)

Expected behavior

expect it to save a wav file

Try using our fork (available via pip install coqui-tts). This repo is not updated anymore and the streaming code here doesn't work with recent versions of transformers - that's probably the reason, but hard to tell because you didn't include the full error log.
