Initially I got a called subprocess error I tried to decode the output by changing line 116 in language_model.py to

try: devnull = open(os.devnull, 'wb')

    print([MKGRAPH_PATH,
                    proto_langdir,
                    txt_fst_file.name,
                    hclg_filename])

    sub_result = subprocess.check_output([MKGRAPH_PATH,
                    proto_langdir,
                    txt_fst_file.name,
                    hclg_filename],
                    stderr=devnull)
except subprocess.CalledProcessError as e:
    sub_result = e.output.decode()
