CodeBERT-base-mlm

Pretrained weights for CodeBERT: A Pre-Trained Model for Programming and Natural Languages.

Training Data

The model is trained on the code corpus of CodeSearchNet

Training Objective

This model is initialized with Roberta-base and trained with a simple MLM (Masked Language Model) objective.

Usage

from transformers import RobertaTokenizer, RobertaForMaskedLM, pipeline

model = RobertaForMaskedLM.from_pretrained('microsoft/codebert-base-mlm')
tokenizer = RobertaTokenizer.from_pretrained('microsoft/codebert-base-mlm')

code_example = "if (x is not None) <mask> (x>1)"
fill_mask = pipeline('fill-mask', model=model, tokenizer=tokenizer)

outputs = fill_mask(code_example)
print(outputs)

Expected results:

Reference

1. Bimodal CodeBERT trained with MLM+RTD objective (suitable for code search and document generation)
2. 🤗 Hugging Face's CodeBERTa (small size, 6 layers)
