Fyi they are working on a nice feature in meson: But it's not there yet. |

* Add a mode to turn lc0 into a chunk data rescorer powered by Tablebase. * Add some stats. * Add secondary rescoring using wdl to reduce back propigation of blunders a bit. * Add policy distribution adjust support to rescorer. * Track the game outcomes, and the change to the start of the game * Add DTZ based assistance for secondary rescoring. * Change move count to a moves remaining to potentially use for modulating target value. * Use DTZ for pawnless 3 piece positions as a substitue for DTM to adjust move_count to be more correct * another fix. * More fixing. * Getting things compiling again. * Make rescorer more obvious. * reorder to match struct order. * Actually update the version when converting to v4 format. * Implement the threading support. * Fix compilation issues on some compilers. * More compilation fixing. * Fix off by one. * Add support for root probe policy boosting for minimum dtz in winning positions. * Fix test compile. * Fix missing option. * Add a counter. * Log if policy boost is for a move labelled illegal. * Add a histogram for total amount of boosted policy per boosted position. * Distribute boost rather than apply to all - also log before and after dists. * Add gaviotatb code for later use in dtm_boost * Fix compile issue on linux. * Prepare logic for dtm policy boost. * Load gaviota tb if specified. * Probe gaviota to decide which 'safe' moves are most deserving of boost based on dtm. * First attempt at supporting arbitrary starting point training data for rescorer. * Fix missing brackets. * Some fixes. * Avoid crashes from walking history before start of provided game information. * Some more merge fixes. * Fix some formatting. * Only process .gz files, don't crash out on invalid files, don't create output until input has been read. * Don't keep partially valid files. * Add basic range validation for input data. * Don't create writer any earlier than needed. * Fix decoding castling moves for the new Move format. * Validate game moves for legality. * Also log illegal move if it passes probability check but fails the real check. * Fix another merge error. * Compile fix for linux. * Plies left in rescorer (#1) * Rescore move_count using Gaviota TBs * Fix lczero-common commit * Add condition for Gaviota move_count rescoring * Post merge fixup for the kings/knights change in board. * Rescore tb v5 (#2) * Make lc0 output v5 training data. * Finish merge of v5 data into rescorer tb. * Fixes for rescoring v4 data. * Revert some unneeded formatting changes. * Support FRC input_format in rescoring. * Add some very important missing break statements... * Fix merge. * Change movement decode to not rely on there being any history planes filled in. Since that will not always be the case for input type 3. * Minimum changes to make it compile again post merge. * Input format 3 support. * Fix data range checks were incorrect for format 3 and 2. * Fix up bugs with chess 960 castle moves that leave a rook or king in place. * Post merge compile fixups for renames. * Add support for hectoplies and hectoplies armageddon to validate, and fixup the merge of latest code. * More fixes for type 4 and 132. * Add input format conversion support to rescorer. * Better match for training. * Add canonical v2 format to rescorer. * Add a utility for substituting policy from higher quality data into main data. * Fix missing option and add some commented out diagnostic code. * More cleanup in comments. * Handle empty policy-substitutions dir and input dir better. * Don't keep chunks that are marked as not for training. * More fixes for handling files with placeholder chunks. * Add 'deblunderer' Completely untested... * Fix some bugs in deblunder. * simplify windows rescorer build (#4) Co-authored-by: borg323 <[email protected]> * Tweak windows build file. * Some updates for writer.h/cc for v6 * Update rescorer loop.cc for V6. * Some additional validations to do with played_idx/best_idx. * make appveyor build the rescorer (#7) Co-authored-by: borg323 <[email protected]> * subproject for gaviota tb files (#8) Co-authored-by: borg323 <[email protected]> * 'Fix' for build on windows Probably should be fixed some other way... * Fix my breakage.

This patch can be used to disable specific lc0 backends using the meson command line. The original intention was to disable the TensorFlow backend, which can be done by specifying -Dtf=false, but the final version allows -Dopencl=false -Dcudnn=false and -Dblas=false as well.
