To ease the file writing process and occupy less ram you can use the -chunksize flag, so that your data will be written in chunks, e.g -chunksize 10000. h5 file endings and the program will still parse the right files. This command takes as input the path to you pgn file and wirtes the bitboards to an h5 file at the path specified via -save_position. To extract bitboards from all positions of all games in a pgn file open a terminal in the tools foder and run: python3 pgn_extract.py. If you are stuck display the help with python3 path/to/tool.py -h. The tools folder provides useful command line scripts to preprocess pgn files that contain chess positions. Extract positions from your own database for search and metric learning However, as you can find out by playing with the notebook the similarity search with bitboards is not optimal, this is why we explore metric learning later on. The following databases contain high quality games that are generated from freely available lichess games, where we only extracted games with both players above elo 2000 and a time control greater or equal 60+1 seconds. I provide some more precompiled databases. The demo enables you to search a small database of bitbaords for similar positions. demo/query_bitboard_db.ipynb or see some examples live in your browser. Now that you installed the package you can ckeck out the demo notebook at. Demo: Search your positions in a provided database

Feel free to try out your own embedding models to improve the embedding based search retrieval. Additionally The projects experiments with embeddings learned from bitboards using the triplet neural network architecture.

You can also build your own database with the provided tools. This repository allows you to search a chess position against billions of chess positions in millions of games and retrieve similar positions. Please check back in a bit, to see the new much better version of this project! chesspos: embedding learning for chess positionsĮmbedding based chess position search and embedding learning for chess positions Into its own repository, since it is strictly speaking a downstream application.
