比较两个数，返回一个 bool 类型的张量

import tensorflow as tf
#判断每一个数是否大于0.5
greater = tf.greater([1.,0.2,0.5,0.,2.,3.], 0.5)
#判断每一个数是否小于0.5
less = tf.less([1.,0.2,0.5,0.,2.,3.], 0.5)
#判断每一个数是否大于等于0.5
greater_equal=tf.greater_equal([1.,0.2,0.5,0.,2.,3.], 0.5)
#判断每一个数是否小于等于0.5
less_equal=tf.less_equal([1.,0.2,0.5,0.,2.,3.], 0.5)
#判断每一个数是否等于0.5
equal = tf.equal([1.,0.2,0.5,0.,2.,3.], 0.5)
#判断每一个数是否不等于0.5
not_equal=tf.not_equal([1.,0.2,0.5,0.,2.,3.], 0.5)
