## Installation

```bash
pip install datasets
````

---

## Quick Start

```python
from datasets import load_dataset

ds = load_dataset(
    "Programmer-RD-AI/sinhala-english-singlish-translation", 
    split="train"
)
print(ds[0])
# {
#   "sinhala": "මෙය මගේ ප්‍රධාන අයිතියයි",
#   "english": "This is my headright.",
#   "singlish": "meya mage pradhana ayithiyayi"
# }
```

## Usage Examples

### Load into Pandas

```python
import pandas as pd
from datasets import load_dataset

df = load_dataset(
    "Programmer-RD-AI/sinhala-english-singlish-translation", 
    split="train"
).to_pandas()

print(df.head())
```

### Fine-tuning a Translation Model

```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM, Trainer, TrainingArguments

# 1. Tokenizer & model
tokenizer = AutoTokenizer.from_pretrained("t5-small")
model     = AutoModelForSeq2SeqLM.from_pretrained("t5-small")

# 2. Preprocess
def preprocess(ex):
    inputs  = "translate Sinhala to English: " + ex["sinhala"]
    targets = ex["english"]
    tokenized = tokenizer(inputs, text_target=targets, truncation=True)
    return tokenized

train_dataset = ds.map(preprocess, remove_columns=ds.column_names)
  
# 3. Training
args = TrainingArguments(
    output_dir="outputs",
    num_train_epochs=3,
    per_device_train_batch_size=16,
)
trainer = Trainer(
    model=model,
    args=args,
    train_dataset=train_dataset,
    tokenizer=tokenizer
)
trainer.train()
```
