TensorFlow saved models can be used to save a copy of your network that is decoupled from the Python source for it. This is enabled by saving a TensorFlow graph describing the computation and a checkpoint containing the value of weights. The first thing to do in order to create a saved mo...
You can learn more about Tensorflow’s scan here. Below, I use scan with an LSTM so as to compare to the dynamic_rnn using Tensorflow above. Because LSTMs store their state in a 2-tuple, and we’re using a 3-layer network, the scan function produces, as final_states below, a 3-...

训练过程的session 周期性的保存 checkpoints,然后 eval session 和 inference session 就可以读取checkpoints。下面的例子展示了这两种方法的不同。 前一种方法:三个模型都在一个图里,并且共享一个 session。 with tf.variable_scope('root'): train_inputs = tf.placeholder() train_op, loss = BuildTrain...
Part-2: Tensorflow tutorial-> Building a small Neural network based image classifier: Network that we will implement in this tutorial is smaller and simpler (than the ones that are used to solve real-world problems) so that you can train this on your cpu as well. While training, images fr...
