v1.0.3: teaching improvements & lower memory

Several people reported issues with the included KataGo binaries and settings, causing out of memory errors. This version reverts back to having a maximum board size of 19x19 and changes some KataGo settings, which should solve most memory problems.

In addition:

• you can now disable analysis in teaching mode, reducing the temptation to peek at the best move with a keyboard shortcut.
• In teaching mode, you can hover over next moves (including moves that were just undone) to see the predicted followup.
• The 'sweep' analysis tool now goes in order of policy, giving you better insight into good moves faster.
• minor bug fixes and tweaking of the AI settings.

The binaries included are of the latest and yet unreleased katago version, since katrain uses features only released in the 1.3.5+bs29 version.

Note that rectangular boards from 2x2 up to 19x19 are still supported, but for those with big GPUs that like playing with strangely large board sizes and breaking the AI, there is a katago-bs52 binary included which supports up to the maximum board size of 52x52 SGF files allow.

KaTrain v1.0 pre-release

This near-complete rewrite includes a number of new features which help you analyze your game and play against AIs:

New features:

• A number of weaker AI players to play against
• A redesign of the feedback system, aiming to be simpler and give point loss rather than temperature based things.
• New game / configuration options available within the program.
• A proper sgf reader/writer.
• Score graph.
• Nicer looking UI
• Support for non-square board.
• View neural network policy.
• And much more!

Quickstart

• Download the file 'KaTrainv1.x.zip' under 'Assets' below, and unzip it.
• Start KaTrain.exe in the directory.
• You can right-click most button or checkbox labels to get a tooltip with help.
• To analyze a game, load it using the open folder button in the bottom right.
• To play against AI, pick an AI from the dropdown and either 'human' or 'teach' for yourself and start playing.

Update

v1.0.1: minor bug fixes to tall rectangular boards and SGF file improvements.
v1.0.2: minor bug fixes to PV on root, engine restart on settings changed. reduced installer download from 300 to 75mb

v0.9 with windows executable

Thanks to early testers from reddit for great feedback, the program should now be easier on the eyes and better in reviewing.

• You can load SGF files and rewind to the start to review while the program analyzes your game in the background!
• Instead of having all coloured dots or none, the default is to show only the last moves for less distraction.
• Lots of bug fixes and improved stability.

In addition I've managed to package the program with PyInstaller to give windows users an easier way to download it, see the attached KaTrain.v0.9.zip file for a stand-alone program. Simply extract the files and double-click KaTrain.exe!
