```bash
pip install transformers torch pandas scikit-learn tqdm
```

- **Requirements** 📋: Python 3.8+, ~20MB storage for model and dependencies.
- **Optional** 🔧: CUDA-enabled GPU for faster training/inference.
- **Model Download** 📥: Grab the pre-trained model from [Hugging Face](https://huggingface.co/boltuix/bert-local).

---

## Quickstart: Dive In 🚀

```python
from transformers import AutoModelForSequenceClassification

# 📥 Load the fine-tuned intent classification model
model = AutoModelForSequenceClassification.from_pretrained("boltuix/bert-local")

# 🏷️ Extract the ID-to-label mapping dictionary
label_mapping = model.config.id2label

# 📋 Convert and sort all labels to a clean list
supported_labels = sorted(label_mapping.values())

# ✅ Print the supported categories
print("✅ Supported Categories:", supported_labels)
```

## Training the Model 🧠

bert-local is trained using **bert-mini** for multi-class text classification. Here’s how to train it:

### Prerequisites
- Dataset in CSV format with `text` (query) and `label` (category) columns.
- Example dataset structure:
  ```csv
  text,label
  "Need help with taxes","accounting firm"
  "Where’s the nearest airport?","airport"
  ...
  ```
