Usage

from transformers import BertForPreTraining, BertTokenizer

# Load the model and tokenizer
model = BertForPreTraining.from_pretrained('bansalaman18/uncased_L-2_H-512_A-8')
tokenizer = BertTokenizer.from_pretrained('bansalaman18/uncased_L-2_H-512_A-8')

# 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.
