This repository contains unofficial BERT implmentation using PyTorch Framework.

• To build vocabulary, run following code snippet

python build_vocab.py

• To pretrain BERT model, run following code snippet with options

python main.py \
    --mode MODE
    --max_len MAX_LEN
    --max_pred MAX_PRED
    --num_layers NUM_LAYERS
    --num_heads NUM_HEADS
    --num_segments NUM_SEGMENTS
    --hidden_dim HIDDEN_DIM
    --ffn_dim FFN_DIM
    --dropout DROPOUT

• Finish build_iter and make_instance logic on large dataset
• Apply WordPiece tokenization
• Add Fine-tuning stage
