# TeenyTinyLlama-460m-IMDB
TeenyTinyLlama is a series of small foundational models trained in Brazilian Portuguese.
This repository contains a version of [TeenyTinyLlama-460m](https://huggingface.co/nicholasKluge/TeenyTinyLlama-460m) (`TeenyTinyLlama-460m-IMDB`) fine-tuned on the the [IMDB dataset](https://huggingface.co/datasets/christykoh/imdb_pt).
## Details
- **Number of Epochs:** 3
- **Batch size:** 16
- **Optimizer:** `torch.optim.AdamW` (learning_rate = 4e-5, epsilon = 1e-8)
- **GPU:** 1 NVIDIA A100-SXM4-40GB
## Usage
Using `transformers.pipeline`:
```python
from transformers import pipeline
text = "Esqueceram de mim 2 é um dos melhores filmes de natal de todos os tempos."
classifier = pipeline("text-classification", model="nicholasKluge/TeenyTinyLlama-460m-IMDB")
classifier(text)
# >>> [{'label': 'POSITIVE', 'score': 0.9971244931221008}]
```
## Reproducing
To reproduce the fine-tuning process, use the following code snippet:
```python
# IMDB
! pip install transformers datasets evaluate accelerate -q
import evaluate
import numpy as np
from datasets import load_dataset
from transformers import AutoTokenizer, DataCollatorWithPadding
from transformers import AutoModelForSequenceClassification, TrainingArguments, Trainer
# Load the task
dataset = load_dataset("christykoh/imdb_pt")
# Create a `ModelForSequenceClassification`
model = AutoModelForSequenceClassification.from_pretrained(
"nicholasKluge/TeenyTinyLlama-460m",
num_labels=2,
id2label={0: "NEGATIVE", 1: "POSITIVE"},
label2id={"NEGATIVE": 0, "POSITIVE": 1}
)
tokenizer = AutoTokenizer.from_pretrained("nicholasKluge/TeenyTinyLlama-460m")
# Preprocess the dataset
def preprocess_function(examples):
return tokenizer(examples["text"], truncation=True, max_length=256)
dataset_tokenized = dataset.map(preprocess_function, batched=True)
# Create a simple data collactor
data_collator = DataCollatorWithPadding(tokenizer=tokenizer)
# Use accuracy as an evaluation metric
accuracy = evaluate.load("accuracy")
# Function to compute accuracy
def compute_metrics(eval_pred):
predictions, labels = eval_pred
predictions = np.argmax(predictions, axis=1)
return accuracy.compute(predictions=predictions, references=labels)
# Define training arguments
training_args = TrainingArguments(
output_dir="checkpoints",
learning_rate=4e-5,
per_device_train_batch_size=16,
per_device_eval_batch_size=16,
num_train_epochs=3,
weight_decay=0.01,
evaluation_strategy="epoch",
save_strategy="epoch",
load_best_model_at_end=True,
push_to_hub=True,
hub_token="your_token_here",
hub_model_id="username/model-name-imdb"
)
# Define the Trainer
trainer = Trainer(
model=model,
args=training_args,
train_dataset=dataset_tokenized["train"],
eval_dataset=dataset_tokenized["test"],
tokenizer=tokenizer,
data_collator=data_collator,
compute_metrics=compute_metrics,
)
# Train!
trainer.train()
```
