OSError: bilalRahib/Tiny-LLama-NSFW-Chatbot does not appear to have a file named config.json.

I'm not sure what I'm doing wrong, but I tried with the example here (https://github.com/arcee-ai/mergekit/blob/main/examples/linear.yml) and it worked so my installation is good. I edited the yaml file and selected the models I wanted to merge, and I keep getting the same error on both models :

OSError: bilalRahib/Tiny-LLama-NSFW-Chatbot does not appear to have a file named config.json. Checkout 'https://huggingface.co/bilalRahib/Tiny-LLama-NSFW-Chatbot/main' for available files.

Here is the content of the yaml config file :

models:
  - model: TinyLlama/TinyLlama-1.1B-Chat-v1.0
    parameters:
      weight: 1.0
  - model: bilalRahib/Tiny-LLama-NSFW-Chatbot
    parameters:
      weight: 1.0
merge_method: linear
dtype: float16

Here is the complete traceback :

Hey! This is happening because Tiny-LLama-NSFW-Chatbot is a LoRA, not a full set of model weights. If you specify a base model to apply the LoRA to it will work. So like this, for example:

models:
  - model: TinyLlama/TinyLlama-1.1B-Chat-v1.0
    parameters:
      weight: 1.0
  - model: TinyLlama/TinyLlama-1.1B-intermediate-step-1431k-3T+bilalRahib/Tiny-LLama-NSFW-Chatbot  # base+lora
    parameters:
      weight: 1.0
merge_method: linear
dtype: float16

Ok, thanks Charles ! I'll try this. How can you identify a LoRa on Huggingface, other than the size maybe?

Ok, thanks Charles ! I'll try this. How can you identify a LoRa on Huggingface, other than the size maybe?

You can see that its a lora from the fact that it has a adapter_config.json and adapater_model.safetensors file rather than a config.json and model-x.safetensors file

LoRA stands for Low-Rank Adaptation/Adapter which is where the adapter_model name comes from

Noted, thanks Carsten. Much appreciated.
