# SmartBERT V2 CodeBERT
## Overview
SmartBERT V2 CodeBERT is a pre-trained model, initialized with **[CodeBERT-base-mlm](https://huggingface.co/microsoft/codebert-base-mlm)**, designed to transfer **Smart Contract** function-level code into embeddings effectively.
- **Training Data:** Trained on **16,000** smart contracts.
- **Hardware:** Utilized 2 Nvidia A100 80G GPUs.
- **Training Duration:** More than 10 hours.
- **Evaluation Data:** Evaluated on **4,000** smart contracts.
## Preprocessing
All newline (`\n`) and tab (`\t`) characters in the function code were replaced with a single space to ensure consistency in the input data format.
## Base Model
- **Base Model**: [CodeBERT-base-mlm](https://huggingface.co/microsoft/codebert-base-mlm)
## Training Setup
```python
from transformers import TrainingArguments
training_args = TrainingArguments(
output_dir=OUTPUT_DIR,
overwrite_output_dir=True,
num_train_epochs=20,
per_device_train_batch_size=64,
save_steps=10000,
save_total_limit=2,
evaluation_strategy="steps",
eval_steps=10000,
resume_from_checkpoint=checkpoint
)
```
## How to Use
