BelGPT-2

The 1st GPT-2 model pre-trained on a very large and heterogeneous French corpus (~60Gb).

Usage

You can use BelGPT-2 with 🤗 transformers:

import torch
from transformers import GPT2Tokenizer, GPT2LMHeadModel

# Load pretrained model and tokenizer
model = GPT2LMHeadModel.from_pretrained("antoiloui/belgpt2")
tokenizer = GPT2Tokenizer.from_pretrained("antoiloui/belgpt2")

# Generate a sample of text
model.eval()
output = model.generate(
            bos_token_id=random.randint(1,50000),
            do_sample=True,   
            top_k=50, 
            max_length=100,
            top_p=0.95, 
            num_return_sequences=1
)

# Decode it
decoded_output = []
for sample in output:
    decoded_output.append(tokenizer.decode(sample, skip_special_tokens=True))
print(decoded_output)

Data

Below is the list of all French copora used to pre-trained the model:
