be very serious (except for the very perfect protection circuit), light will damage several components, heavy may appear "burn" phenomenon (only very small probability). Fortunately, lubricating oil can effectively reduce the wear and tear of the switch, but also can be more effective to suppress the ignition, so the metal contact with a variety of switches to add one or two drops of lubricating oil is essential. Other computer peripherals also exist

This section describes the use of RNN LSTM to do the MNIST classification method, RNN compared to CNN, the speed may be slower, but can save more memory space.Initialization first we can initialize some variables, such as the learning rate, the number of node units, the number of RNN layers, and so on:Learning_rate = 1e-33 ten = Tf.placeholder (Tf.float32, [])Then you need to declare the MNIST data generator: as TF from = input_data.read_data_sets ('mnist_data/', one_hot=true)Next, the gener
