After selecting "Parler" in Gradio, it won't start up: ImportError: cannot import name 'EncoderDecoderCache' from 'transformers.cache_utils'

[phazei]

I installed v2 fresh. I tried xtts, it worked nice, then I selected parler from the gui, but it got an error. I figure because it hadn't installed it. I quit the cli, started it again, and instead of asking what engine I wanted on boot, it just gave me an error. I tried a few times, tried the pip install again, nothing.

I think I got my model names wrong. I think it happens if I select parler in the gui, and then it gets stuck that way unless I mess with the config file manually

I worked around it by changing "firstrun_model": true in the config and picked piper since it was small to redownload, it let me launch again at least. I'm running the standalone version.

I found the model voices download page for parler and downloaded it, but it didn't fix it.

Hi @phazei

Please read this here. Apologies for your install problems, but I hope that may give you a way forward. If it does and you are happy with that resolution, please close the ticket for now. If not, feel free to leave it open and I will return to it when I can.

Thanks

It's no big deal, I'm sure it'll work itself out once you're available again, good luck with your fam!

/extensions/alltalk_tts/system/tts_engines

In there you will have tts_engines.json, and its backup(the last known good settings).

If you change the engine loaded to something valid, like xtts perhaps or piper by default

{
                "engine_loaded": "piper",
                "selected_model": "piper",
                "engines_available": [
                    {
                        "name": "parler",
                        "selected_model": "parler - parler_tts_mini_v0.1"
                    },
                    {
                        "name": "piper",
                        "selected_model": "piper"
                    },
                    {
                        "name": "vits",
                        "selected_model": "vits - tts_models--en--vctk--vits"
                    },
                    {
                        "name": "xtts",
                        "selected_model": "xtts - xttsv2_2.0.3"
                    }
                ]
            }

Thanks the default config there, you can clear out the selected models if those models dont exist and are throwing an error, but yeah just load into something else thats valid.

This doesnt fix the fundamental flaw, but this will get you back up and running, just dont select that engine again for the time being till you fix it.
