nsorflow学习之tf.cast类型转换函数
tf.cast(x, dtype, name=None) //此函数是类型转换函数,把x的类型转换成dtype指定的类型
-
Args:
-
-
x: A Tensor or SparseTensor.
-
dtype: The destination type.
-
name: A name for the operation (optional).
-
Returns:
-
-
A Tensor or SparseTensor with same shape as x.
-
-
Raises:
-
-
TypeError: If x cannot be cast to the dtype.
参数
- x:输入
- dtype:转换目标类型
- name:名称
Tensor
例子
-
#将0/1转换成bool类型
-
-
import tensorflow as tf
-
-
a = tf.Variable([ 1, 0, 0, 1, 1])
-
b = tf.cast(a,dtype=tf.bool)
-
sess = tf.Session()
-
sess.run(tf.initialize_all_variables())
-
print(sess.run(b))
-
#[ True False False True True]
