This is an easy example to type a dense layer in keras vs tensorflow

keras.py

# Keras implementation

from keras.models import Sequential
from keras.layers import Dense

model = Sequential()
model.add(Dense(32, input_shape=(16,)))

tf.py

# Tensorflow implementation

import tensorflow as tf

x1 = tf.layers.dense(z, 4*4*512)
inputs_z = tf.placeholder(
               tf.float32,
               (None, z_dim),
               name=‘input_z’
            )
