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

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
