I am trying:
import subprocess
subprocess.call(["file.sh"])
But I keep getting:
Traceback (most recent call last):
File "project.py", line 85, in <module>
subprocess.call(["file.sh"])
File "/usr/local/lib/python2.7/subprocess.py", line 522, in call
return Popen(*popenargs, **kwargs).wait()
File "/usr/local/lib/python2.7/subprocess.py", line 710, in __init__
errread, errwrite)
File "/usr/local/lib/python2.7/subprocess.py", line 1335, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
However when I try and run the script from the shell bash file.sh it works. So I'm confused as to why it doesn't work?
I am not committed to using subprocess so if there are other options please let me know.
The call function of the subprocess package runs the command specified in arg as a list of strings (to simplify).
To call your file you have put in your script:
import subprocess
subprocess.call(["sh", "file.sh"])

I'm trying to to write a simple python app and launch it using TorchX following this Quickstart guide. Following commands are executed in my home directory:
pip3 install "torchx[dev]"
Write a simple python program using vim editor vi my_app.py
# my_app.py
%%writefile my_app.py
import sys
print(f"Hello, {sys.argv[1]}!")
Execute the app via torchx run as torchx run --scheduler local_cwd utils.python --script my_app.py "your name".
And then I get a long error:

I was completely confused about this, is there anyone who could help me figure out? I was just a rookie on Python, thanks for a bunch!
While running buildout on window with Python 2.6 for Plone 4.2, All went fine. but while running instance on foreground it give me this window specific (presume) error about some file missing.
I remember on older version of Plone for installing PyWin type libary, I had to copy some dll file to window system file and I also done same for this. still I am having this error.
Any suggestion/advise would great help.
Thank for taking your time.
