TensorFlow函数(七)tf.argmax()
tf.argmax(input, dimension, name=None)
参数:
- input:输入数据
- dimension:按某维度查找。
dimension=0:按列查找;
dimension=1:按行查找;
返回:
- 最大值的下标
a = tf.constant([1.,2.,3.,0.,9.,])
b = tf.constant([[1,2,3],[3,2,1],[4,5,6],[6,5,4]])
with tf.Session() as sess:
sess.run(tf.argmax(a, 0))
with tf.Session() as sess:
sess.run(tf.argmax(b, 0))
with tf.Session() as sess:
sess.run(tf.argmax(b, 1))
输出:
4
输出:
[3, 2, 2]
输出:
[2, 0 ,2, 0]
