使用python subprocess调用pikafish.exe文件无法工作 #48

Closed DimariaW closed 12 months ago

Describe the issue

本人在使用python 开发一个象棋游戏, 有需求调用 皮卡鱼提供AI支持, 目前打算采用subprocess直接调用exe文件,但是不work

python 代码如下:

import subprocess

p = subprocess.Popen("pikafish-bmi2.exe", stdin=subprocess.PIPE, stdout=subprocess.PIPE)

cmd = "uci\nisready\nposition startpos\ngo movetime 1000\n"

out, errs = p.communicate(cmd.encode())

print(out.decode("utf-8"))`

程序输出如下:

option name UCI_Elo type spin default 1350 min 1350 max 2850
option name UCI_WDLCentipawn type check default true
option name UCI_ShowWDL type check default false
option name EvalFile type string default pikafish.nnue
uciok
readyok
info string NNUE evaluation using pikafish.nnue enabled
bestmove a0a1

看上去皮卡鱼没有搜索就直接返回了, 有解决办法吗?

Expected behavior

import subprocess

p = subprocess.Popen("pikafish-bmi2.exe", stdin=subprocess.PIPE, stdout=subprocess.PIPE)
cmd = "uci\nisready\nposition startpos\ngo movetime 1000\n"
out, errs = p.communicate(cmd.encode())

print(out.decode("utf-8"))

以下内容由OpenAI GPT4辅助编写：

你需要等待软件加载完成之后也就是接收到readyok后再发送position startpos和go movetime 1000之类的，下面是一个正确调用的案例：

import subprocess

# 启动子进程
p = subprocess.Popen("pikafish-bmi2.exe", stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True, bufsize=1, universal_newlines=True)

# 发送 "uci" 和 "isready" 指令
p.stdin.write("uci\n")
p.stdin.write("isready\n")
p.stdin.flush()

# 等待 "readyok" 响应
while True:
    output = p.stdout.readline().strip()
    print(f"Received: {output}")
    if "readyok" in output:
        break

# 发送其他指令
p.stdin.write("position startpos\n")
p.stdin.write("go movetime 1000\n")
p.stdin.flush()

# 读取输出
while True:
    output = p.stdout.readline().strip()
    print(f"Received: {output}")
    if "bestmove" in output:  # 替换为实际的结束条件
        break

# 关闭子进程
p.terminate()

你想要的效果（即发送isready指令并等待readyok响应，然后再发送其他指令），你可以使用stdin.write()和stdout.readline()方法来分步与子进程进行交互。 注意：

  1. 我使用了text=True和universal_newlines=True选项，这样就可以直接使用字符串进行读写，而不需要进行编码和解码。
  2. 使用bufsize=1来设置行缓冲，这样stdout.readline()就可以每次读取一行。
  3. 请替换"bestmove"为实际的结束条件。 这样，你就可以实现发送isready后等待readyok响应，然后再发送其他指令的效果了。希望这能帮助你！
