在Windows 10/Pycharm中使用Vagrant从Python调用FastDowndown planner

Question

我试图使用python脚本中的Vagrant调用FastDowndown planner

我尝试了os库，但失败了

然后我在子流程中尝试了不同的方法：

    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)

但是这些都被ssh卡住了，这是不正确的，启动一个流浪环境需要很多时间

这是我的工作环境：

多谢各位

我已经尝试了这些链接，但我无法让Vagrant选项出现在pycharm中： https://www.jetbrains.com/help/pycharm/vagrant-support.html#

Answer 1

经过大量研究，我设法从python脚本中直接运行一个ssh命令到vagrant。在这种情况下，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。您可以使用此选项将输出打印到终端：

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

您可以在-t之后运行多个命令，用分号'command1; command2;...'分隔from this answer（我没有尝试过）

您可以使用子流程库而不是操作系统，并且可以将output字符串变量拆分为具有output=output.split()的字符串列表

我希望我能提供帮助，因为vagrant文档并不完整，而且Windows的在线示例也不多
