KaTrain Bug and Suggestions

[RobertJasiek]

SYNTAX

For Windows, the manual ought to describe the syntax of, and give examples for, the command line for
a) paths without blanks,
b) paths with blanks,
c) commands with gtp,
d) commands without gtp,
e) commands with -model,
f) commands without -model,
g) commands with -config,
h) commands without -config
etc. as far as such variants are possible. Currently, I guess that the following is an example with a correct syntax but I cannot be sure due to bugs:

Code: Select all

C:\katago\katago.exe gtp -model C:\katago\b18.bin.gz -config C:\katago\gtp_custom.cfg

PATH TO KATAGO MODEL FILE

KaTrain 1.7.2.0 for Windows writes in General & Engine Settings, for example,

Code: Select all

Path to KataGo model file = C:/baduk/lizzie/KataGo40b.gz

In Windows, this is misleading as it suggests an apparently wrong syntax for the command line. Windows paths use backslashes instead of slashes. Therefore, the following with backslashes should be written:

Code: Select all

Path to KataGo model file = C:\baduk\lizzie\KataGo40b.gz

BUG

I use Windows 11 Pro 64b, Baduk AI Megapack 4_18_0 x64 and its KaTrain 1.7.2.0. In Lizzie, the following command line works:

Code: Select all

C:\katago\katago.exe gtp -model C:\katago\b18.bin.gz -config C:\katago\gtp_custom.cfg

In KaTrain, this command line does not work, although I guess that it has a correct syntax. For details, see

In Windows CMD inputs, "/" can be used instead of "\". You can also mix these in one full filename.

Windows' output uses only "\", of course.

According to https://www.lifein19x19.com/viewtopic.p ... 08#p278208
KaTrain is not buggy but expects a different command line and CFG file:

If analysis_config.cfg is missing, copy analysis_example.cfg to analysis_config.cfg . In KaTrain | General & Engine Settings | Override set a command line like this:

C:\<path>\katago.exe analysis -model C:\<path>\<model_name>.bin.gz -config C:\<path>\analysis_config.cfg

This works for me for a KataGo OpenCL version. Whether CUDA or TensorRT versions work with the same kind of command, I need to test later.

If gtp_custom.cfg is the tuning file, editing of the contents of analysis_config.cfg may be necessary for (much) faster analysis by KataGo.
