Error during supervised learning

[shine]

I'm trying to teach model by set of 4000 games in PGN file. I'm using Python 3.6.3 and Tensorflow without GPU. Here is error traceback: ` puser@vmi148103:~/chess-alpha-zero$ python3 src/chess_zero/run.py sl 2018-03-09 19:48:42,418@chess_zero.manager INFO # config type: mini ['/home/puser/chess-alpha-zero/data/play_data/Ivanchuk.pgn'] found 4033 games done reading concurrent.futures.process._RemoteTraceback: """ Traceback (most recent call last): File "/usr/lib/python3.6/concurrent/futures/process.py", line 175, in _process_worker r = call_item.fn(*call_item.args, **call_item.kwargs) File "src/chess_zero/worker/sl.py", line 140, in get_buffer white_elo, black_elo = int(game.headers["WhiteElo"]), int(game.headers["BlackElo"]) ValueError: invalid literal for int() with base 10: '' """

The above exception was the direct cause of the following exception:

Traceback (most recent call last): File "src/chess_zero/run.py", line 20, in manager.start() File "src/chess_zero/manager.py", line 73, in start return sl.start(config) File "src/chess_zero/worker/sl.py", line 25, in start return SupervisedLearningWorker(config).start() File "src/chess_zero/worker/sl.py", line 58, in start env, data = res.result() File "/usr/lib/python3.6/concurrent/futures/_base.py", line 425, in result return self.__get_result() File "/usr/lib/python3.6/concurrent/futures/_base.py", line 384, in __get_result raise self._exception ValueError: invalid literal for int() with base 10: '' ` Any ideas what can be wrong here?

it appears your PGN file has a non-digit in one of WhiteELO/BlackELO tags.
