Chess Alpha Zero

This service uses Chess Alpha Zero to play chess with reinforcement learning by AlphaGo Zero methods.

It is part of our third party DNN Model Services.

Getting Started

Requirements

Development

Clone this repository:

$ git clone https://github.com/singnet/dnn-model-services.git
$ cd dnn-model-services/services/zeta36-chess-alpha-zero

Running the service:

To get the ORGANIZATION_ID and SERVICE_ID you must have already published a service (check this link).

Create the SNET Daemon's config JSON file (snetd.config.json).

{
   "DAEMON_END_POINT": "DAEMON_HOST:DAEMON_PORT",
   "IPFS_END_POINT": "http://ipfs.singularitynet.io:80",
   "BLOCKCHAIN_NETWORK_SELECTED": "BLOCKCHAIN_NETWORK",
   "PASSTHROUGH_ENABLED": true,
   "PASSTHROUGH_ENDPOINT": "http://SERVICE_GRPC_HOST:SERVICE_GRPC_PORT",  
   "ORGANIZATION_ID": "ORGANIZATION_ID",
   "SERVICE_ID": "SERVICE_ID",
   "LOG": {
       "LEVEL": "debug",
       "OUTPUT": {
            "TYPE": "stdout"
           }
   }
}

For example (using the Ropsten testnet):

$ cat snetd.config.json
{
   "DAEMON_END_POINT": "0.0.0.0:7058",
   "IPFS_END_POINT": "http://ipfs.singularitynet.io:80",
   "BLOCKCHAIN_NETWORK_SELECTED": "ropsten",
   "PASSTHROUGH_ENABLED": true,
   "PASSTHROUGH_ENDPOINT": "http://localhost:7003",
   "ORGANIZATION_ID": "snet",
   "SERVICE_ID": "zeta36-chess-alpha-zero",
   "LOG": {
       "LEVEL": "debug",
       "OUTPUT": {
           "TYPE": "stdout"
           }
   }
}

Note that we set DAEMON_HOST = 0.0.0.0 because this service will run inside a Docker container.

Install all dependencies:

$ pip3.6 install -r requirements.txt

Generate the gRPC codes:

$ sh buildproto.sh

Clone the chess-alpha-zero repository:

$ git clone https://github.com/Zeta36/chess-alpha-zero.git

Start the service and SNET Daemon:

$ python3.6 run_alpha_zero_service.py

Calling the service:

The board has this layout:

    a b c d e f g h
-------------------
8 | r n b q k b n r
7 | p p p p p p p p
6 | . . . . . . . .
5 | . . . . . . . .
4 | . . . . . . . .
3 | . . . . . . . .
2 | P P P P P P P P
1 | R N B Q K B N R

Uppercase letters are white pieces and lowercase are black.

Each letter represents the following pieces:

P|p: pawns
R|r: rooks
N|n: knights
B|b: bishops
Q|q: queens
K|k: kings

Inputs:

  • uid: The user id to keep playing the same game (optional, if not set the service will generate a random UID and send it back).
  • move: <col_1><row_1><col_2><row_2>.
    • <col_1>: column where the piece is.
    • <row_1>: row where the piece is.
    • <col_2>: column to where the piece will be moved.
    • <row_2>: row to where the piece will be moved.
  • cmd: A specific command to interact with the service (optional).
    • "restart": restart the game, keeping the UID.
    • "finish": finish the game, deleting the UID.

Local (testing purpose):

$ python3.6 test_alpha_zero_service.py 
Endpoint (localhost:7003): 
Method (play): 
UID (empty): human_player
Move (e2e4): 
CMD (empty): 

response:

Through SingularityNET (follow this link to learn how to publish a service and open a payment channel to be able to call it):

Assuming that you have an open channel to this service:

$ snet client call snet zeta36-chess-alpha-zero default_group play '{"move": "g1f3"}'

response:
UID: b8f24aa8f25a5dddbfaf
board: 
    a b c d e f g h
