Usage

python

from transformers import BertForPreTraining, BertTokenizer

# Load the model and tokenizer
model = BertForPreTraining.from_pretrained('bansalaman18/uncased_L-4_H-256_A-4')
tokenizer = BertTokenizer.from_pretrained('bansalaman18/uncased_L-4_H-256_A-4')

# Example usage
text = "Hello, this is a sample text for BERT."
inputs = tokenizer(text, return_tensors='pt')
outputs = model(**inputs)

Training Data

This model was originally trained on the same data as the standard BERT models:

English Wikipedia (2500M words)
BookCorpus (800M words)

Conversion Details

This model was converted from the original TensorFlow checkpoint to PyTorch format using a custom conversion script with the Hugging Face Transformers library.
