## Installation 🛠️
|
306 |
+
|
307 |
+
Get started with bert-local:
|
308 |
+
|
309 |
+
```bash
|
310 |
+
pip install transformers torch pandas scikit-learn tqdm
|
311 |
+
```
|
312 |
+
|
313 |
+
- **Requirements** 📋: Python 3.8+, ~20MB storage for model and dependencies.
|
314 |
+
- **Optional** 🔧: CUDA-enabled GPU for faster training/inference.
|
315 |
+
- **Model Download** 📥: Grab the pre-trained model from [Hugging Face](https://huggingface.co/bert-local).
|
316 |
+
|
317 |
+
---
|
318 |
+
|
319 |
+
## Quickstart: Dive In 🚀
|
320 |
+
|
321 |
+
```python
|
322 |
+
from transformers import AutoModelForSequenceClassification
|
323 |
+
|
324 |
+
# 📥 Load the fine-tuned intent classification model
|
325 |
+
model = AutoModelForSequenceClassification.from_pretrained("bert-local")
|
326 |
+
|
327 |
+
# 🏷️ Extract the ID-to-label mapping dictionary
|
328 |
+
label_mapping = model.config.id2label
|
329 |
+
|
330 |
+
# 📋 Convert and sort all labels to a clean list
|
331 |
+
supported_labels = sorted(label_mapping.values())
|
332 |
+
|
333 |
+
# ✅ Print the supported categories
|
334 |
+
print("✅ Supported Categories:", supported_labels)
|
335 |

## Training the Model 🧠
|
340 |
+
|
341 |
+
bert-local is trained using **bert-mini** for multi-class text classification. Here’s how to train it:
|
342 |
+
|
343 |
+
### Prerequisites
|
344 |
+
- Dataset in CSV format with `text` (query) and `label` (category) columns.
|
345 |
+
- Example dataset structure:
|
346 |
+
```csv
|
347 |
+
text,label
|
348 |
+
"Need help with taxes","accounting firm"
|
349 |
+
"Where’s the nearest airport?","airport"
|
350 |
+
...
|
351 |
+
```
|
352 |
+
|
353 |
+
### Training Code
|
354 |
+
```python
|
355 |
+
