如何更改 condor 中的设置，以便用户不必 chmod 他们的实验脚本？

Question

当前秃鹰集群的用户必须做:

chmod a+x /home/user/automl-meta-learning/results_plots/main.py

能够使用condor_submit运行他们的脚本。如何使秃鹰设置使用户不再需要这样做?

这里是一个用户示例提交脚本:

如果要直接执行.py文件，则需要设置执行位，这是Linux/Unix的习惯用法，与HTCondor没有什么关系。也就是说，在命令行上，如果您想运行

$ ./foo.py

foo.py需要设置可执行位。如果想解决这个问题，可以将foo.py作为参数传递给python，然后运行

$ python foo.py

则不需要设置可执行位。为了在HTCondor中模拟这一点，你可以将/usr/bin/python或/usr/bin/python3设置为可执行文件，并将foo.py设置为参数，例如

executable = /usr/bin/python
arguments = foo.py

这些都假设您有一个共享的文件系统。如果您使用HTCondor的文件传输将数据发送到工作节点，则需要多几行。
