The Mistral 7B mannequin is on the market within the HuggingFace as nicely. With this, we will use the Hugging Face AutoTrain to fine-tune the mannequin for our use circumstances. Hugging Face’s AutoTrain is a no-code platform with Python API that we will use to fine-tune any LLM mannequin obtainable in HugginFace simply.
This tutorial will train 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 package deal, which you’ll run utilizing the next code.
pip set up -U autotrain-advanced
Additionally, we’d use the Alpaca pattern dataset from HuggingFace, which required datasets package deal to accumulate and the transformers package deal to control the Hugging Face mannequin.
pip set up datasets transformers
Subsequent, we should format our information for fine-tuning the Mistral 7B mannequin. Usually, 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. Nonetheless, we’d use a special textual content format for the bottom and instruction fashions throughout the fine-tuning.
First, let’s have a look at the dataset we used for our pattern.
from datasets import load_dataset
import pandas as pd
# Load the dataset
prepare= load_dataset("tatsu-lab/alpaca",cut up="prepare[:10%]")
prepare = pd.DataFrame(prepare)
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 larger information. Our information pattern seems just like the picture beneath.

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 have to carry out something. Nonetheless, I would supply a code if in case you have one other dataset that wants the formatting.
def text_formatting(information):
# If the enter column shouldn't be 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
prepare['text'] = prepare.apply(text_formatting, axis =1)
For the Hugging Face AutoTrain, we would wish the information within the CSV format in order that we’d save the information with the next code.
prepare.to_csv('prepare.csv', index = False)
Then, transfer the CSV consequence right into a folder known as information. That’s all you could 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 offered by Mistral, proven within the code block beneath.
<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 information with none enter for the chat mannequin.
train_chat = prepare[train['input'] == ''].reset_index(drop = True).copy()
Then, we might reformat the information 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 applicable for fine-tuning the Mistral 7B Instruct v0.1 mannequin.

With all of the preparation set, we will 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 supply the knowledge 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’d 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’d provoke the mannequin parameter data within the variables beneath. 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 will tweak many parameters however is not going to talk about them on this article. Some ideas to enhance the LLM fine-tuning embrace utilizing a decrease studying charge to take care of 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 if in case you have a reminiscence drawback.
When all the knowledge is prepared, we’ll arrange the surroundings to simply accept all the knowledge now we have 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

$( [[ "$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’d attempt the mannequin with an enter instance.
input_text = "Give three ideas 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:
Give three ideas for staying wholesome.
- Eat a balanced food plan: Be sure to incorporate loads of fruits, greens, lean proteins, and entire grains in your food plan. It will enable you get the vitamins you could keep wholesome and energized.
