Finetuning Hunyuan - missing model_index.json

[kraja]

I followed this procedure, but I encountered a problem that I don't think is on my side.

https://github.com/NSFW-API/TripleX/blob/master/guides/fine_tuning_hunyuan_video_with_finetrainers.md

First, I had to solve what appears to be a requirement for a different configuration format, because the script reported this error when executed:

train.py: error: the following arguments are required: --dataset_config

But the unsolvable problem was when the script tries to download the file https://huggingface.co/tencent/HunyuanVideo/resolve/main/model_index.json- and it's not there.
I searched but simply couldn't find it anywhere. And I also can't manage to create it.
