How to get weights in tf.layers.dense?

Question

I wanna draw the weights of tf.layers.dense in tensorboard histogram, but it not show in the parameter, how could I do that?

Answer 1

I came across this problem and just solved it. tf.layers.dense 's name is not necessary to be the same with the kernel's name's prefix. My tensor is "dense_2/xxx" but it's kernel is "dense_1/kernel:0". To ensure that tf.get_variable works, you'd better set the name=xxx in the tf.layers.dense function to make two names owning same prefix. It works as the demo below:

l=tf.layers.dense(input_tf_xxx,300,name='ip1')
with tf.variable_scope('ip1', reuse=True):
    w = tf.get_variable('kernel')

By the way, my tf version is 1.3.
