System requirement and GTP setup #3

Closed aniljava closed 8 years ago

aniljava commented 8 years ago

I tested Tested cnnPlayerMCTSV2.lua on 750 Ti, it responded normally upto 6 moves, after that it stopped responding and started freezing computer.

Also, when using cnnPlayerMCTSV2.lua with gogui, the debug messages with line ends, i think interferes with the GTP protocol triggering the timeout on the gogui.

A guide on GTP setup and expected system requirement would be nice.

How many GPUs do you use? In my case, I tested 1 and 4 GPUs and it works fine.

Did you set the time limit? --time_limit 10 will restrict the time usage to 10-11 sec.

I have not tried using it with gogui yet...

I am using single GPU.

It is working now after removing all debug messages board dumps and recompiling. .c codes are printing to STDOUT instead of STDERR causing problem with GTP, after manually commenting out the printf from .c and .lua codes, it is working as expected with gogui.

I have not checked how instances are created for games, i think last time, i might had multiple instance running after CTRL+C on cnnPlayer. killall luajit and restarting the cnn_evaluator and cnnPlayerMCTSV2.lua solved the problem.

awesome! glad this is solved now.
