[Bug] TypeError: 'NoneType' object is not subscriptable

[bropines]

Describe the bug

Traceback (most recent call last):
File "G:\TTS\script.py", line 15, in
tts.tts_to_file(text="Hello world!", speaker=tts.speakers[0], language=tts.languages[0], file_path="output.wav")
TypeError: 'NoneType' object is not subscriptable

To Reproduce

I took an example from the readme

import torch
from TTS.api import TTS

# Get device
device = "cuda" if torch.cuda.is_available() else "cpu"

# List available 🐸TTS models and choose the first one
model_name = TTS().list_models()[0]
# Init TTS
tts = TTS(model_name).to(device)

# Run TTS
# ❗ Since this model is multi-speaker and multi-lingual, we must set the target speaker and the language
# Text to speech to a file
tts.tts_to_file(text="Hello world!", speaker=tts.speakers[0], language=tts.languages[0], file_path="output.wav")```

Of course, I understand that I'm stupid and could mess up in the code, but I took the simplest and default example

Hi,

I have the exact same problem, i'm on Windows too.

As i was looking for a solution i notice the problem seems to came from the list (tts.model, tts.speakers and tts.language) that are empty (none).

For instance i was able to make Coqui working with :

from TTS.api import TTS
tts = TTS("tts_models/multilingual/multi-dataset/xtts_v1", gpu=True)

# generate speech by cloning a voice using default settings
tts.tts_to_file(text="This is a test",
                file_path="output.wav",
                speaker_wav="C:\\youruser\\yourfolder\\yourfile.wav",
                #speaker =""
                language="en")

@bropines : if you want to test xtts with this script you can download a youtube video as wav and with one person speaking, the results are clearely not amazing, but at least it validate that the model is working with your setup.

For now i'm trying to check if i can pass direct value instead, like in this script but i didn't find any list of speakers or languages at the moment.

Let me know if someone find a workaround or if there is something to do. :)

The latest commit 4033db5 added a new voice model without updating the examples.

It appears that this change will skip the new model and point you to the old one that has those features implemented.
model_name = TTS().list_models()[1]

Ran into the same problem getting started and went diving into the code.

Looks like a lot of models are inconsistent in a couple ways. This new one and a few others seem to not have tts --model_name "tts_models/multilingual/multi-dataset/xtts_v1" --list_speaker_idxs working or implemented.

I assume the fix will be to implement it in the new model instead of just changing the documentation.

I just need to voice a conditional srt file and I just wanted to push in a model, but I don’t even understand which one would be suitable for this and how to use everything

Im getting the same error for this code

import torch
from TTS.api import TTS

# Get device
device = "cuda" if torch.cuda.is_available() else "cpu"

# List available 🐸TTS models and choose the first one
model_name = TTS().list_models()[0]
# Init TTS
tts = TTS(model_name).to(device)

# Run TTS
# ❗ Since this model is multi-speaker and multi-lingual, we must set the target speaker and the language
# Text to speech with a numpy output
wav = tts.tts("This is a test! This is also a test!!", speaker=tts.speakers[0], language=tts.languages[0])
# Text to speech to a file
tts.tts_to_file(text="Hello world!", speaker=tts.speakers[0], language=tts.languages[0], file_path="output.wav")

Error TypeError: 'NoneType' object is not subscriptable

I would like to use the XTTS model which i think located at TTS().list_models()[0]

@ahmedosman2001

I would like to use the XTTS model which i think located at TTS().list_models()[0]

Then read the docs https://tts.readthedocs.io/en/dev/models/xtts.html

Also yes that should be the correct index.
