if __name__ == "__main__": tf.app.run()

仰天大笑出门去，我辈岂是蓬蒿人。这篇文章主要讲述if __name__ == " __main__" : tf.app.run()相关的知识，希望能为你提供帮助。

if __name__ == "__main__": means current file is executed under a shell instead of imported as a module.

the job of tf.app.run() is to first set the global flags for later usage like

from 
tensorflow.python.platform 
import 
flags

f = flags.FLAGS
【if __name__ == " __main__" : tf.app.run()】and then run your custom main function with a set of arguments.

if name == "main": tf.app.run()
