Error when trying to train a style

[rycossette]

First time I've tried to train a style verses faces/people. Just copied over the Colab this morning to make sure it was the latest.

Training styles seems a little confusing to me...I'm trying to train it on about 50 of my 3D character renders I've done.

Settings I used are:
UNet Training Steps: 1000
Text Encoder Training Steps: 350
Text Encoder Concept Training Steps: 1000

instance images are named: rmcchar42 (1) etc

concept images are just a few of the instance images. Maybe that's dumb, not really sure what else to put there or how much good that section even does.

Here is the error I get:

Traceback (most recent call last):
  File "/usr/local/lib/python3.8/dist-packages/diffusers/configuration_utils.py", line 372, in load_config
    config_dict = cls._dict_from_json_file(config_file)

    obj, end = self.scan_once(s, idx)

During handling of the above exception, another exception occurred:

Something went wrong

open /content/stable-diffusion-custom/scheduler/scheduler_config.json and remove the comma

Thanks for the quick response!

I have no idea where that file is or how to edit it on the colab. I searched both the list of files in the colab, and on my gdrive, neither that file, nor even the stable-diffusion-custom dir is anywhere to be found.

Where do I find/edit it?

in the colab file explorer in the left side
