The Mistral 7B mannequin is accessible within the HuggingFace as properly. With this, we are able to use the Hugging Face AutoTrain to fine-tune the mannequin for our use instances. Hugging Face’s AutoTrain is a no-code platform with Python API that we are able to use to fine-tune any LLM mannequin accessible in HugginFace simply.
This tutorial will educate us to fine-tune Mistral AI 7B LLM with Hugging Face AutoTrain. How does it work? Let’s get into it.
To fine-tune the LLM with Python API, we have to set up the Python bundle, which you’ll be able to run utilizing the next code.
pip set up -U autotrain-advanced
Additionally, we might use the Alpaca pattern dataset from HuggingFace, which required datasets bundle to accumulate and the transformers bundle to control the Hugging Face mannequin.
pip set up datasets transformers
Subsequent, we should format our information for fine-tuning the Mistral 7B mannequin. Basically, there are two foundational fashions that Mistral launched: Mistral 7B v0.1 and Mistral 7B Instruct v0.1. The Mistral 7B v0.1 is the bottom basis mannequin, and the Mistral 7B Instruct v0.1 is a Mistral 7B v0.1 mannequin that has been fine-tuned for dialog and query answering.
We would wish a CSV file containing a textual content column for the fine-tuning with Hugging Face AutoTrain. Nevertheless, we might use a distinct textual content format for the bottom and instruction fashions in the course of the fine-tuning.
First, let’s take a look at the dataset we used for our pattern.
from datasets import load_dataset
import pandas as pd
# Load the dataset
practice= load_dataset("tatsu-lab/alpaca",break up="practice[:10%]")
practice = pd.DataFrame(practice)
The code above would take ten p.c samples of the particular information. We might solely want that a lot for this tutorial as it could take longer to coach for greater information. Our information pattern seems to be just like the picture under.

The dataset already comprises the textual content columns with a format we have to fine-tune our LLM mannequin. That’s why we don’t must carry out something. Nevertheless, I would offer a code when you have one other dataset that wants the formatting.
def text_formatting(information):
# If the enter column isn't empty
if information['input']:
textual content = f"""Beneath is an instruction that describes a job, paired with an enter that gives additional context. Write a response that appropriately completes the request.nn### Instruction:n{information["instruction"]} nn### Enter:n{information["input"]}nn### Response:n{information["output"]}"""
else:
textual content = f"""Beneath is an instruction that describes a job. Write a response that appropriately completes the request.nn### Instruction:n{information["instruction"]}nn### Response:n{information["output"]}"""
return textual content
practice['text'] = practice.apply(text_formatting, axis =1)
For the Hugging Face AutoTrain, we would wish the info within the CSV format in order that we might save the info with the next code.
practice.to_csv('practice.csv', index = False)
Then, transfer the CSV outcome right into a folder known as information. That’s all you should put together the dataset for fine-tuning Mistral 7B v0.1.
If you wish to fine-tune the Mistral 7B Instruct v0.1 for dialog and query answering, we have to comply with the chat template format supplied by Mistral, proven within the code block under.
<s>[INST] Instruction [/INST] Mannequin reply</s>[INST] Observe-up instruction [/INST]
If we use our earlier instance dataset, we have to reformat the textual content column. We might use solely the info with none enter for the chat mannequin.
train_chat = practice[train['input'] == ''].reset_index(drop = True).copy()
Then, we might reformat the info with the next code.
def chat_formatting(information):
textual content = f"<s>[INST] {information['instruction']} [/INST] {information['output']} </s>"
return textual content
train_chat['text'] = train_chat.apply(chat_formatting, axis =1)
train_chat.to_csv('train_chat.csv', index =False)
We’ll find yourself with a dataset acceptable for fine-tuning the Mistral 7B Instruct v0.1 mannequin.

With all of the preparation set, we are able to now provoke the AutoTrain to fine-tune our Mistral mannequin.
Let’s arrange the Hugging Face AutoTrain surroundings to fine-tune the Mistral mannequin. First, let’s run the AutoTrain setup utilizing the next command.
Subsequent, we would offer the data required for AutoTrain to run. For this tutorial, let’s use the Mistral 7B Instruct v0.1.
project_name="my_autotrain_llm"
model_name="mistralai/Mistral-7B-Instruct-v0.1"
Then, we might add the Hugging Face data if you wish to push your mannequin to the repository.
push_to_hub = False
hf_token = "YOUR HF TOKEN"
repo_id = "username/repo_name"
Lastly, we might provoke the mannequin parameter data within the variables under. You possibly can change them to see if the result’s good.
learning_rate = 2e-4
num_epochs = 4
batch_size = 1
block_size = 1024
coach = "sft"
warmup_ratio = 0.1
weight_decay = 0.01
gradient_accumulation = 4
use_fp16 = True
use_peft = True
use_int4 = True
lora_r = 16
lora_alpha = 32
lora_dropout = 0.045
We are able to tweak many parameters however is not going to talk about them on this article. Some suggestions to enhance the LLM fine-tuning embody utilizing a decrease studying charge to keep up pre-learned representations and vice versa, avoiding overfitting by adjusting the variety of epochs, utilizing bigger batch measurement for stability, or adjusting the gradient accumulation when you have a reminiscence downside.
When all the data is prepared, we are going to arrange the surroundings to just accept all the data we’ve got arrange beforehand.
import os
os.environ["PROJECT_NAME"] = project_name
os.environ["MODEL_NAME"] = model_name
os.environ["PUSH_TO_HUB"] = str(push_to_hub)
os.environ["HF_TOKEN"] = hf_token
os.environ["REPO_ID"] = repo_id
os.environ["LEARNING_RATE"] = str(learning_rate)
os.environ["NUM_EPOCHS"] = str(num_epochs)
os.environ["BATCH_SIZE"] = str(batch_size)
os.environ["BLOCK_SIZE"] = str(block_size)
os.environ["WARMUP_RATIO"] = str(warmup_ratio)
os.environ["WEIGHT_DECAY"] = str(weight_decay)
os.environ["GRADIENT_ACCUMULATION"] = str(gradient_accumulation)
os.environ["USE_FP16"] = str(use_fp16)
os.environ["USE_PEFT"] = str(use_peft)
os.environ["USE_INT4"] = str(use_int4)
os.environ["LORA_R"] = str(lora_r)
os.environ["LORA_ALPHA"] = str(lora_alpha)
os.environ["LORA_DROPOUT"] = str(lora_dropout)
We might use the next command to run the AutoTrain in our pocket book.
!autotrain llm

--lora-dropout ${LORA_DROPOUT}
--weight-decay ${WEIGHT_DECAY}
--gradient-accumulation ${GRADIENT_ACCUMULATION}
$( [[ "$USE_FP16" == "True" ]] && echo "--fp16" )
$( [[ "$USE_PEFT" == "True" ]] && echo "--use-peft" )
$( [[ "$USE_INT4" == "True" ]] && echo "--use-int4" )
$( [[ "$PUSH_TO_HUB" == "True" ]] && echo "--push-to-hub --token ${HF_TOKEN} --repo-id ${REPO_ID}" )
If the fine-tuning course of succeeds, we could have a brand new listing of our fine-tuned mannequin. We might use this listing to check our newly fine-tuned mannequin.
from transformers import AutoModelForCausalLM, AutoTokenizer
model_path = "my_autotrain_llm"
tokenizer = AutoTokenizer.from_pretrained(model_path)
mannequin = AutoModelForCausalLM.from_pretrained(model_path)
With the mannequin and tokenizer prepared to make use of, we might strive the mannequin with an enter instance.
input_text = "Give three suggestions for staying wholesome."
input_ids = tokenizer.encode(input_text, return_tensors="pt")
output = mannequin.generate(input_ids, max_new_tokens = 200)
predicted_text = tokenizer.decode(output[0], skip_special_tokens=True)
print(predicted_text)
Output:
