ошибка подпроцесса, приводящая к необработанной ошибке

Question

Я управляю газетным проектом от https://github.com/fhamborg/news-please/blob/master/newsplease/__main__.py от subprocess

         cmd = ["python",r"/media/dhruvagupta/F428F6FA28F6BB26/backup dhruva/python/New folder/training/news-please-master/news-please-master/newsplease/__main__.py","-c /newsplease/config/"]
        j = psutil.Popen(cmd)

Я получаю эту ошибку
