Trouble with mergekit

I tried using the mergekit.

I used this provided yaml file as a template, just changed the model names.

models:

  • model: mistralai/Mistral-7B-v0.1
    #no parameters necessary for base model
  • model: mistralai/Mistral-7B-Instruct-v0.2
    parameters:
    density: 0.5
    weight: 0.5
  • model: BioMistral/BioMistral-7B
    parameters:
    density: 0.5
    weight: 0.5

merge_method: ties
base_model: mistralai/Mistral-7B-v0.1
parameters:
normalize: false
int8_mask: true
dtype: float16

It did not work and just said “error”.

I did leave this field empty:

HF Write Token

How do tokens work, do you need one to use the mergekit ?

Was the error because of the token or something else ?

Can you make a model straight to GGUF instead of float 16 ?
