RuntimeError: Need to specify cache dir to merge adapters

I tried merging multiple adapters together. Here's the yaml I use:

models:
  - model: mistralai/Mistral-Nemo-Instruct-2407+/home/xxxx/AI/LLM/models/LORA/Gutenberg-Doppel_1024/
    parameters:
      weight: 0.3
      density: 0.9
  - model: mistralai/Mistral-Nemo-Instruct-2407+/home/xxxx/AI/LLM/models/LORA/lumamaid_1024/
    parameters:
      weight: 0.25
      density: 0.9
  - model: mistralai/Mistral-Nemo-Instruct-2407+/home/xxxx/AI/LLM/models/LORA/MN-12B-Lyra-v4_1024/
    parameters:
      weight: 0.3
      density: 0.9
  - model: mistralai/Mistral-Nemo-Instruct-2407+/home/xxxx/AI/LLM/models/LORA/Nemo-abliterated_1024/
    parameters:
      weight: 0.1
      density: 0.7
  - model: mistralai/Mistral-Nemo-Instruct-2407+/home/xxxx/AI/LLM/models/LORA/Rocinante_1024/
    parameters:
      weight: 0.2
      density: 0.9
merge_method: della_linear
base_model: /home/xxxx/.cache/huggingface/hub/models--mistralai--Mistral-Nemo-Instruct-2407/snapshots/e17a136e1dcba9c63ad771f2c85c1c312c563e6b
parameters:
  epsilon: 0.05
  lambda: 1
dtype: bfloat16

Problem is, when I use execute this code, the terminal output:

RuntimeError: Need to specify cache dir to merge adapters

Where do I have to specify my cache dir ? And why do I have to specify it ?
