Tensorflow error(一):__iter__() is only supported when eager execution is enabled.

错误语句:RuntimeError: iter() is only supported inside of tf.function or when eager execution is enabled.

解决方法:I fixed it by enabling eager execution after importing tensorflow:

import tensorflow as tf
 
tf.enable_eager_execution()
