[Bug] json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

[darkzbaron]

Describe the bug

Can't generate with Coqui Studio voices

To Reproduce

When running

tts = TTS(model_name="coqui_studio/en/Torcull Diarmuid/coqui_studio", progress_bar=False) tts.tts_to_file(text="This is a test.", file_path="out.wav")

I get that error json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Expected behavior

Voice generated

Logs

No response

        "python": "3.9.16",

    }
}

Additional context

Also I find that voices generated with xTTS local are far from what is generated in Coqui Studio, any explanation to that?

Getting similar error whenever I try to use the library.

/home/wenniu/anaconda3/envs/tts/lib/python3.9/site-packages/TTS/.models.json This json file format has an extra comma, cause ttf --list_models to be wrong:

delete comma at the end of line 11.

The fix took some time to be deployed on Pypi , can you please try now with pip install -U TTS?

[fallinbryan]

@erogol ,

Looks like the fix didn't deploy to Pypi... I just installed TTS with pip install TTS and after reading the bug also ran pip install -U TTS

I am getting this same error when following the instructions on the README TTS(cs_api_model="XTTS").list_models()

also if coqui_studio model is loaded, the tts_to_file won't work at all and I get the JSONDecodeError tts = TTS(model_name="coqui_studio/en/Torcull Diarmuid/coqui_studio", progress_bar=False)

[darkzbaron]

Thanks for the push @erogol ! print(TTS().list_models())

was not working in any case, now it just does not work when trying to list models from Coqui studio. Essentially this does not work: models = TTS(cs_api_model="XTTS").list_models()

it returns Expecting value: line 1 column 1 (char 0)

When I am trying to generate audio with

tts.tts_to_file(text="This is a test.", file_path=OUTPUT_PATH)

I get

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Thanks so much!

[ColemanDunn]

Same here. Can't follow the guide in the readme because of this error.

[ColemanDunn]

data = res.read() in

def list_voices(self):
        """List custom voices created by the user."""
        conn = http.client.HTTPSConnection("app.coqui.ai")
        url = self.MODEL_ENDPOINTS[self.model]["list_voices"]
        conn.request("GET", f"{url}", headers=self.headers)
        res = conn.getresponse()
        data = res.read()
        return [Speaker(s, True) for s in json.loads(data)["result"]]

results in HTML encoded as btyes, NOT json.

[nirbhaysinghnarang]

Running into the same error, any workarounds?

[Aliasmk]

Also having this problem with the sample code from the readme. I can list the models but tts.tts_to_file(text="This is a test.", file_path="./test.wav") gives me the error json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0).

[ColemanDunn]

@erogol any idea why this got closed?

I think I've fixed this, please check out the PR for details on what's happening and how I fixed it https://github.com/coqui-ai/TTS/pull/3138
