ldpc_decoders's Issues

codeword -1 error

When running python main.py bsc 1200_3_6_ldpc MSA --codeword -1 --params 0.1 --console --max-iter 10, I receive an AttributeError : AttributeError: 'Code' object has no attribute 'cb' from line 38 of main.py

Is there no support for random codewords with large encoding matrices, or am I making a mistake in my command?
