# **Fine-Tuned Sentiment Analysis Deployment Guide**  

This guide explains how to **fine-tune, save, upload, and deploy** a sentiment analysis model using **Hugging Face Transformers, Gradio, and Hugging Face Spaces**.  

---

## **1. Prerequisites**  
Before proceeding, ensure you have the following installed:  

### **Install Required Libraries**
```bash
pip install gradio transformers torch scipy numpy
```

If you're using **TensorFlow-based models**, also install:
```bash
pip install tensorflow
```

### **Hugging Face Authentication**
Login to Hugging Face CLI:
```bash
huggingface-cli login
```
(You'll need an **access token** from [Hugging Face](https://huggingface.co/settings/tokens).)

---

## **2. Fine-Tune Your Sentiment Analysis Model**
### **Training a Custom Sentiment Model**
If you haven't already fine-tuned a model, you can do so using `Trainer` from Hugging Face:  

```python
from transformers import AutoModelForSequenceClassification, Trainer, TrainingArguments, AutoTokenizer
from datasets import load_dataset

# Load dataset
dataset = load_dataset("imdb")  # Example dataset

# Load tokenizer and model
model_name = "cardiffnlp/twitter-roberta-base-sentiment-latest"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name, num_labels=3)

# Tokenize dataset
def preprocess(examples):
    return tokenizer(examples["text"], truncation=True, padding="max_length")

tokenized_datasets = dataset.map(preprocess, batched=True)

# Training Arguments
training_args = TrainingArguments(
    output_dir="./fine_tuned_sentiment_model",
    evaluation_strategy="epoch",
    save_strategy="epoch",
    per_device_train_batch_size=8,
    per_device_eval_batch_size=8,
    num_train_epochs=3,
    weight_decay=0.01,
    logging_dir="./logs",
)

# Trainer
trainer = Trainer(
    model=model,
    args=training_args,
    train_dataset=tokenized_datasets["train"],
    eval_dataset=tokenized_datasets["test"],
)

# Train Model
trainer.train()

# Save Model
model.save_pretrained("./fine_tuned_sentiment_model")
tokenizer.save_pretrained("./fine_tuned_sentiment_model")
```

---

## **3. Upload Model to Hugging Face Hub**
Once you've fine-tuned your model, upload it to **Hugging Face Model Hub**:  

### **1. Install `huggingface_hub`**
```bash
pip install huggingface_hub
```

### **2. Push Model to Hugging Face**
```python
from huggingface_hub import notebook_login
from transformers import AutoModelForSequenceClassification, AutoTokenizer

notebook_login()  # Authenticate

# Define model name
repo_name = "your-username/sentiment-analysis-model"

# Load fine-tuned model
model = AutoModelForSequenceClassification.from_pretrained("./fine_tuned_sentiment_model")
tokenizer = AutoTokenizer.from_pretrained("./fine_tuned_sentiment_model")

# Push model to Hugging Face Hub
model.push_to_hub(repo_name)
tokenizer.push_to_hub(repo_name)
```

Your fine-tuned model is now available at **https://huggingface.co/your-username/sentiment-analysis-model**.

---

## **4. Deploy Sentiment Model Using Gradio**
To create a **Gradio-based web interface**, follow these steps:

### **1. Create `app.py`**
Save the following script as `app.py`:

```python
import gradio as gr
import numpy as np
from transformers import AutoModelForSequenceClassification, AutoTokenizer, AutoConfig
from scipy.special import softmax

# Load fine-tuned model from Hugging Face Hub
MODEL_NAME = "your-username/sentiment-analysis-model"  # Replace with your model repo
model = AutoModelForSequenceClassification.from_pretrained(MODEL_NAME)
tokenizer = AutoTokenizer.from_pretrained(MODEL_NAME)
config = AutoConfig.from_pretrained(MODEL_NAME)

# Preprocess function
def preprocess(text):
    new_text = []
    for t in text.split(" "):
        t = '@user' if t.startswith('@') and len(t) > 1 else t
        t = 'http' if t.startswith('http') else t
        new_text.append(t)
    return " ".join(new_text)

# Sentiment Prediction Function
def predict_sentiment(text):
    text = preprocess(text)
    encoded_input = tokenizer(text, return_tensors='pt')
    output = model(**encoded_input)
    scores = output[0][0].detach().numpy()
    scores = softmax(scores)

    # Get sentiment labels and scores
    ranking = np.argsort(scores)[::-1]
    result = {config.id2label[ranking[i]]: round(float(scores[ranking[i]]) * 100, 2) for i in range(scores.shape[0])}
    return result

# Gradio Interface
interface = gr.Interface(
    fn=predict_sentiment,
    inputs=gr.Textbox(lines=3, placeholder="Enter text..."),
    outputs=gr.Label(),
    title="Fine-Tuned Sentiment Analysis",
    description="Enter a sentence to analyze its sentiment (Positive, Neutral, Negative).",
)

# Launch the app
interface.launch()
```

---

## **5. Upload to Hugging Face Spaces**
### **1. Create a Hugging Face Space**
- Go to [Hugging Face Spaces](https://huggingface.co/spaces).  
- Click **Create new Space**.  
- Choose **Gradio** as the SDK.  
- Set the repository name (e.g., `sentiment-analysis-app`).  
- Click **Create Space**.  

### **2. Upload Files**
- Upload `app.py` in the Space repository.
- Create and upload a `requirements.txt` file with:
  ```
  gradio
  transformers
  torch
  scipy
  numpy
  ```

### **3. Deploy the Model**
Once the files are uploaded, Hugging Face will **automatically install dependencies** and **launch the app**. You can access it via the **public URL** provided by Hugging Face.

---

## **6. Testing & Sharing**
Once deployed, test the model by entering different texts and see the predicted sentiment. Share the **public Hugging Face Space link** with others to let them use it.

---

## **7. Summary**
### ✅ **Fine-tune a sentiment analysis model**  
### ✅ **Upload it to Hugging Face Model Hub**  
### ✅ **Deploy it using Gradio & Hugging Face Spaces**  
### ✅ **Make it publicly accessible for users**  

🚀 **Your fine-tuned sentiment analysis model is now LIVE!** 🎉
