【Tensorflow】tf.argmax函数

import tensorflow as tf


a=tf.get_variable(name=‘a‘,
                  shape=[3,4],
                  dtype=tf.float32,
                  initializer=tf.random_uniform_initializer(minval=-1,maxval=1))
b=tf.argmax(input=a,axis=0)
c=tf.argmax(input=a,dimension=1)   #此处用dimesion或用axis是一样的
sess = tf.InteractiveSession()
sess.run(tf.initialize_all_variables())
print(sess.run(a))
