mistralai/Mistral-7B-v0.1 · KeyError:'mistral"' while finetuning mistral-7B-v0.1 in aws sagemaker

Apr 9

Hi,
I am using this https://github.com/huggingface/notebooks/blob/main/sagemaker/24_train_bloom_peft_lora/sagemaker-notebook.ipynb script to finetune the model. The training job is getting stopped due to this error

/usr/local/lib/python3.10/dist-packages/transformers/models/auto/configuration_auto.py in getitem(self, key)
732 return self._extra_content[key]
733 if key not in self._mapping:
734 raise KeyError(key)
735 value = self._mapping[key]
736 module_name = model_type_to_module_name(key)
KeyError: 'mistral'

I did search solutions and tried few
I tried to upgrade the transformers library, downloaded the transformers library from source, in the model config.json file I modified the model_type to "llama" instead of "mistral".
But still facing the same issue
I have been stuck at this issue from last 3 days, unable to finetune the model, my work is paused because of this issue.
Please suggest how do I solve this issue

is there any solution for this error, I'm getting the same error too. Below is my code snippet

Code

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig

base_model_id = "mistralai/Mistral-7B-v0.1"
bnb_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_use_double_quant=True,
bnb_4bit_quant_type="nf4"
)
model = AutoModelForCausalLM.from_pretrained(base_model_id, quantization_config=bnb_config)

Error

Hi the issue is solved for me by updating transformer library to 4.38.0.
