CLOP in cutechess-cli debug

Post by Albert Silver » Tue May 22, 2018 2:35 am

I'm trying to get CLOP working but can't seem to get it started but no idea why. I get this error message:

2018-05-21 23:32:24 ===== Starting: Testing =====
2018-05-21 23:32:29 Run
2018-05-21 23:32:29 id = 0 (machine1); Seed = 0; Starting new sample
2018-05-21 23:32:29 id = 0 (machine1); Seed = 0; Error: No Outcome.
StandardOutput:

StandardError:

2018-05-21 23:32:29 id = 0 stopped. RunningProcessors = 0
2018-05-21 23:32:29 Stop

I'm guessing I am doing something silly, but cannot figure out what. Can anyone help? Here is my CLOP file:

Code: Select all

# See DummExperiment.clop for documentation about file format
Script C:/Users/Albert/Chess/cutechess/cutechess-cli.exe

And this is the .py file:

On your clop file you should have something like the following.

Code: Select all

Script "C:/Python27/python.exe" C:/chess/clop-cutechess-cli.py

That did the trick, so many thanks. I am having trouble with the UCI options though when configuring the engines. Some are more than one word and have spaces. Any idea how best to solve this?

Why is that a problem? The UCI protocol allows for multiple words in the name of options.

I usually use engines.json file.

Create engines.json file located on cutechess-cli.exe
Add entries like the following.

Code: Select all

[
    { 
      "command" : "stockfish_9_x64_popcnt.exe",
      "name" : "Stockfish_9",
      "options" : [ 
         { 
            "name" : "Hash",
            "value" : 128
         }		 
      ], 
      "protocol" : "uci",
      "workingDirectory" : "C:/chess/engines/nobook/stockfish-9-win/Windows"
    },
    { 
      "command" : "Hiarcs14WCSC.exe", 
      "name" : "HIARCS_14_UCI_Elo_1600", 
      "options" : [ 
         { 
            "name" : "Hash", 
            "value" : 64 
         },
	 { 
            "name" : "Book Learning", 
            "value" : false 
         },
	 { 
            "name" : "Use Tablebases", 
            "value" : "Never"
         },
         { 
            "name" : "UCI_LimitStrength", 
            "value" : true
         },
         { 
            "name" : "UCI_Elo", 
            "value" : 1600
         },
         { 
            "name" : "OwnBook", 
            "value" : false
         }
      ], 
      "protocol" : "uci", 
      "workingDirectory" : "C:/Program Files (x86)/HIARCS Chess/HIARCS 14 WCSC" 
   }
]
Then on python script just use,

Code: Select all

# The engine whose parameters will be optimized
engine = 'conf=HIARCS_14_UCI_Elo_1600'

# A pool of opponents for the engine. The opponent will be
# chosen based on the seed sent by CLOP.
opponents = [
    'conf=Stockfish_9'
]

opponents = [
    'conf=Stockfish_9'

Many thanks again, that was super helpful. I think I need to restart my CLOP session since I suspect I completely misunderstood the TC setting and thought tc=1+1 means 1m+1s and now think it is all seconds... It would explain why the games are going to fast.

It's pretty simple, you defined only 1 engine in json file - LC0. You didn't define Wasp. You have to define both.
Just read the manual for cutechess-cli. You have 2 txt files in cutechess folder where everything is explained.

Any ideas?
It's pretty simple, you defined only 1 engine in json file - LC0. You didn't define Wasp. You have to define both.
Just read the manual for cutechess-cli. You have 2 txt files in cutechess folder where everything is explained.
Actually, the answer was other, but your explanation was plausible, so thanks. I had placed the engines.json file in the cutechess folder, but for CLOP, it needs to be in the CLOP folder.
