AttributeError: 'module' object has no attribute 'main' for tf.app.run()
提问by user288609
I am trying to test a short program, which is pretty simple, shown as follows
我正在尝试测试一个简短的程序，它非常简单，如下所示
import numpy as np
import tensorflow as tf
flags = tf.app.flags
FLAGS = flags.FLAGS
import tensorvision.train as train
import tensorvision.utils as utils
flags.DEFINE_string('name', None,
'Append a name Tag to run.')
flags.DEFINE_string('hypes', 'hypes/medseg.json',
'File storing model parameters.')
if __name__ == '__main__':
tf.app.run()
However, running the program gives the following error message,
但是，运行该程序会出现以下错误消息，
Traceback (most recent call last):
File "train.py", line 43, in <module>
tf.app.run()
File "/devl/tensorflow/tf_0.12/lib/python3.4/site- packages/tensorflow/python/platform/app.py", line 39, in run
main = main or sys.modules['__main__'].main
AttributeError: 'module' object has no attribute 'main'

You either need a "def main(args)" function in your file:
您的文件中需要一个“def main(args)”函数：
import numpy as np
import tensorflow as tf
flags = tf.app.flags
FLAGS = flags.FLAGS
import tensorvision.train as train
import tensorvision.utils as utils
def main(args):
flags.DEFINE_string('name', None,
'Append a name Tag to run.')
flags.DEFINE_string('hypes', 'hypes/medseg.json',
'File storing model parameters.')
if __name__ == '__main__':
tf.app.run()
or tf.app.run() can call an external function
或者 tf.app.run() 可以调用外部函数
tf.app.run(my_func)
