CodeRosetta

Pushing the Boundaries of Unsupervised Code Translation for Parallel Programming (📃Paper, 🔗Website).

CodeRosetta is an EncoderDecoder translation model. It supports the translation of C++, CUDA, and Fortran.
This version of the model is fine-tuned on HPC_Fortran_CPP dataset for Fortran to C++ translation.

How to use

from transformers import AutoTokenizer, EncoderDecoderModel

# Load the CodeRosetta model and tokenizer
model = EncoderDecoderModel.from_pretrained('CodeRosetta/CodeRosetta_fortran2cpp_ft')
tokenizer = AutoTokenizer.from_pretrained('CodeRosetta/CodeRosetta_fortran2cpp_ft')

# Encode the input Fortran Code
input_fortran_code = "program DRB047_doallchar_orig_no\n use omp_lib\n implicit none\n\n character(len=100), dimension(:), allocatable :: a\n character(50) :: str\n integer :: i\n\n allocate (a(100))\n\n !$omp parallel do private(str)\n do i = 1, 100\n write( str, '(i10)' ) i\n a(i) = str\n end do\n !$omp end parallel do\n\n print*,'a(i)',a(23)\nend program"
input_ids = tokenizer.encode(input_fortran_code, return_tensors="pt")

# Set the start token to <CPP>
start_token = "<CPP>"
decoder_start_token_id = tokenizer.convert_tokens_to_ids(start_token)

# Generate the C++ code
output = model.generate(
    input_ids=input_ids, 
    decoder_start_token_id=decoder_start_token_id,
    max_length=256
)

# Decode and print the generated output
generated_code = tokenizer.decode(output[0], skip_special_tokens=True)
print(generated_code)
