Is it possible to do this? Program takes a game , and adds PGN headers with the computed "Eval" for each player. Preserves a game with the added headers.

[DominoA4]

Example:
[Event "Blitz"]
[Site "St. Louis, MO USA"]
[Date "2016.04.29"]
[Round "18.1"]
[White "Fabiano Caruana"]
[Black "Garry Kasparov"]
[Result "0-1"]
[EventDate "2016.04.28"]
[WhiteElo "2795"]
[BlackElo "2812"]
[PlyCount "74"]
[WMaxEval= 0.00]
[BMaxEval = 0.00]
[WMinEval = 0.00]
[BMinEval = 0.00]

I will implement it this weekend.

[fsmosca]

eval_swing v0.4.0 has implementation, please try it.

[DominoA4]

It almost worked out. The error got out:

Traceback (most recent call last):
File "eval_swing.py", line 424, in
main()
File "eval_swing.py", line 420, in main
a.run()
File "eval_swing.py", line 368, in run
df = self.evaluate(game, cnt)
File "eval_swing.py", line 344, in evaluate
my_game.headers['BlackMaxEval'] = str(max(self.b_max_eval))
TypeError: '>' not supported between instances of 'NoneType' and 'float'

Moves are cut for some reason. Link to the original PGN and the result:

Error with another PGN:

Traceback (most recent call last):
File "eval_swing.py", line 424, in

my_game.headers['WhiteMaxEval'] = str(max(self.w_max_eval))
TypeError: '>' not supported between instances of 'NoneType' and 'float'

[DominoA4]

Everything is working! Thank you. The error disappears if you remove the winning games from the PGN.

[DominoA4]

Eval in out_1.pgn and output.txt files do not match
Link: https://pixeldrain.com/u/BdaqVMxT

[fsmosca]

Try the latest v0.5.0, it includes fixing errors in getting WhiteMaxEval etc. for the header.

Process procedure

1. Your need to convert the games in the pgn file into a long sequence of moves using pgn-extract. This way values are properly read by the parser.

Command line:
pgn-extract -w10000 -oMygames_output.pgn Mygames.pgn

I did everything as you say. the error came out:

That particular game has no eval.

Perhaps I just skip this game and not save it in the output or just add ? like,
[WhiteMaxEval "?"]

[DominoA4]

It will be convenient for me to save games without "eval" with the title: [WhiteMaxEval "?"]. So that I can see such games. I'll analyze them later.

Hello! I am successfully using the script eval_swing.py (chessbase). Thanks. Is it possible to make a pgn file processing function with Infinitychess games? Pgn example: https://pixeldrain.com/u/TQ4iXhZq
