Question

我试图通过python子进程运行执行此命令。我当前的目录包含文件夹splitta103，它包含sbd.py文件和model_nb文件夹。

python splitta103 / sbd.py -m splitta103 / model_nb info.txt

这是我的python程序

file = 'info.txt'

print(subprocess.check_output(['splitta103','/','sbd.py','-m','splitta103','/','model_nb',file]))

这是错误

OSError: [Errno 2] No such file or directory

Answer 1

这：print(subprocess.check_output(['splitta103','/','sbd.py','-m','splitta103','/','model_nb','info.txt']))

在命令行上看起来像splitta103 / sbd.py -m splitta103 / model_nb info.txt。

这在命令行上：python splitta103/sbd.py -m splitta103/model_nb info.txt

可以用以下方式制作：['python', 'splitta103/sbd.py', '-m', 'splitta103/model_nb', 'info.txt']

OSError：[Errno 2]没有这样的文件或目录。文件已存在于当前目录中
