Good morning,

I got following issue when running python3 main.py --quiet --depth=12 --strict=True --threads=2 --memory=1024

There was nothing been generated in the tactics.pgn file and there is no error message when running.

pgn-tactics-generator %python3 main.py --quiet --depth=12 --strict=True --threads=2 --memory=1024 Looking up stockfish-osx-x86_64 ... Local stockfish-osx-x86_64 is newer than release pgn-tactics-generator %

The pgn file I used is this one:

Could you help me on this ? Thanks

Try to remove the --quiet param to see if is working. Try --strict=False to make it less strict. Probably you need much more games to get some puzzles.

Thanks for your response.

I have applied above.

I got many similar messages like below and program stopped after Puzzle incomplete.

... and 26 more moves Not Going Deeper: Ambiguous: True Game Over: False Has Best Move: True Puzzle incomplete pgn-tactics-generator %

This pgn should generate some puzzles as it generated some puzzles from http://chesstacticsgenerator.vitomd.com

Is there anything else I can try ?

This pgn should generate some puzzles as it generated some puzzles from http://chesstacticsgenerator.vitomd.com/

No, this script is a lot more strict. Is to generate puzzles, is not just check for blunders, it check that there is only one good solution in the position, that is not ambiguous, etc.

So to generate puzzles you need a lot of games with blunders. Probably if you use a pgn with 50 games you will get some puzzles.
