Webgo

Introduction

Using web browser to visit your computer which is running leela zero to analyse sgf. So you can analyse all kifu anywhere.

Dependency and acknowledge

1. Web page based on WGo.js.
2. Server side based on Leela Analysis Scripts and using python2.7
3. Server side also need Python module: bottle, gevent, gevent-websocket
4. Using some sabaki theme

Server Installation

1. Install python 2.7
2. Install bottle, gevent, gevent-websocket

pip bottle
pip gevent
pip gevent-websocket

3. If you already have your web server, please skip this step

As an alternate web server solution, you can do several step:

cd webgo
python -m SimpleHTTPServer

3.1 download nginx/1.2.8

3.2 modify nginx.conf and set the port and root path

server {
        listen       80;
        server_name  localhost;
        charset utf-8;
        location = / {
            root   C:\web;
            index  index.html index.php;
}

3.3 add sgf as one filetype permitted by server

location ~* \.(htm|html|gif|jpg|jpeg|png|css|js|ico|json|net|sgf)$ {
    root C:\web;
}

4. put all zip content to your web site root

In the example , it's c:\web

Server Configuration

In svr\webgo.py, change to your own leelazero executable path and set the weight name correctly and make sure the leelaz.exe support lz-analyze gtp command

executable = "c:/go/leela-zero/leelaz.exe"
weight = '-wc:/go/weight/62b5417b64c46976795d10a6741801f15f857e5029681a42d02c9852097df4b9.gz'

Sgf library

You can put sgf file under sgf directory

How to run

server side, under cmd.exe run:

c:\python2.7\python webgo.py

browser side, can use pad/phone with any web browser

http://your_ip/webgo.html?sgf=1.sgf&move=50

Using Webgo server in mac

1. Install brew using ruby

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. git clone branch

git clone -b next https://github.com/gcp/leela-zero.git

3. install boost

brew install boost

4. Compile leelaz with boardsize 9 or 19
5. using curl -O or ftp to get weight
6. full-tuner
7. install pip， bottle, gevent, gevent-websocket

sudo easy_install pip
sudo pip install bottle
pip install --user greenlet
pip install --user gevent
pip install --user gevent-websocket

If failed, maybe need to install pyenv, then using pyenv to install another version python pyenv global 2.7.11 to switch version, but wish you lucky
