python - 在 Windows 10/Pycharm 中使用 Vagrant 从 Python 调用 FastDownward planner

Question

我正在尝试使用 python 脚本中的 Vagrant 来调用 FastDownward planner。

我尝试过操作系统库但失败了。

然后我尝试了不同的方法，例如子流程:

    cmd = ['downward/fast-downward.py', "--alias", "lama-first", "/vagrant/domain.pddl", "/vagrant/problem.pddl"]
    retcode = subprocess.call(cmd)

    print(retcode)

它输出:

Traceback (most recent call last):

File "C: / ... .py", line 124, in

main (sys.argv [1:]) File "C: / ... .py", line 111, in main

retcode = subprocess.call (cmd)

File "C: \ .... \ Anaconda3 \ lib \ subprocess.py", line 323, in call

with Popen (* popenargs, ** kwargs) as p:

File "C: \ ...... \ Anaconda3 \ lib \ subprocess.py", line 775, in init restore_signals, start_new_session)

File "C: \ ..... \ Anaconda3 \ lib \ subprocess.py", line 1178, in _execute_child startupinfo)

FileNotFoundError: [WinError 2] Cannot find the specified file from the system

我也尝试过:

    retcode = subprocess.call("vagrant up")
    retcode = subprocess.call("vagrant ssh")
    cmd = ['downward/fast-downward.py', "--alias", "lama-first", "/vagrant/domain.pddl", "/vagrant/problem.pddl"]
    retcode = subprocess.call(cmd)

    print(retcode)

但是这些卡在ssh上并且无法正确，启动vagrant环境需要花费很多时间。

这是我的工作环境:

谢谢

我已经尝试过这些链接，但无法使 Vagrant Option 出现在 pycharm 中: https://www.jetbrains.com/help/pycharm/vagrant-support.html#

Answer 1

经过大量研究，我成功地从我的 python 脚本中直接运行 ssh 命令来 vagrant。在本例中，我运行快速向下规划器:

output=os.popen("vagrant ssh default -- -t 'downward/fast-downward.py --alias lama-first /vagrant/domain.pddl /vagrant/problem.pddl'").read()

上述解决方案将输出字符串保存在变量output中。您可以使用它来将输出打印到终端:

os.system("vagrant ssh default -- -t 'downward/fast-downward.py --alias lama-first /vagrant/domain.pddl /vagrant/problem.pddl'")

并且您可以在-t之后运行多个命令，用分号分隔它们'command1; command2;...' 判断 from this answer (我还没试过)。

您可以使用subprocess库而不是os，并且可以将output字符串变量拆分为带有output的字符串列表=output.split()

我希望能有所帮助，因为 vagrant 文档并不完整，而且 Windows 上的在线示例也不多
