How do I get the weights of a layer in Keras?

Question

I am using Windows 10, Python 3.5, and tensorflow 1.1.0. I have the following script:

import tensorflow as tf
import tensorflow.contrib.keras.api.keras.backe

If you write:

dense1 = Dense(10, activation='relu')(input_x)

Then dense1 is not a layer, it's the output of a layer. The layer is Dense(10, activation='relu')

So it seems you meant:

dense1 = Dense(10, activation='relu')
y = dense1(input_x)

Here is a full snippet:

import tensorflow as tf
from tensorflow.contrib.keras import layers

input_x = tf.placeholder(tf.float32, [None, 10], name='input_x')    
dense1 = layers.Dense(10, activation='relu')
y = dense1(input_x)

weights = dense1.get_weights()
