In the deep learning network structure, the categories of each layer can be divided into these kinds: convolution layer, full connection layer, Relu layer, pool layer and reverse convolution layer. At present, in pixel-level estimation and end-to-end learning problems, full convolution network shows his advantage, there is a very important layer, the convolution of the feature map sampling (deconvolution) to the input image dimension space, is the deconvolution layer. So how does it come to be a

Today, try to install the CPU version of TensorFlow (GPU is not supported) by PIP3 install TensorFlow installation. The installation went well and I ran the simplest Hello wolrd example.
The results do run out and a warning pops up.

TensorFlow and Theano and Keras are deep learning frameworks, TensorFlow and Theano are more flexible and difficult to learn, they are actually a differentiator.
Keras is actually TensorFlow and Keras interface (Keras as the front end, TensorFlow or Theano as the back end), it is also very flexible, and relatively eas
TensorFlow model save/load
When we use an algorithmic model on-line, we must first save the trained model. TensorFlow the way to save the model is not the same as Sklearn, Sklearn is straightforward, a sklearn.externals.joblib dump and load method can be saved and loaded using. and TensorFlow because of the graph, operation these concepts, save and load the mode
1. Installing TensorFlow
Pip
Pip is a Python package installation and management tool, and the installation method is as follows
# ubuntu/linux 64-bit
$ sudo apt-get install python-pip python-dev
# Mac OS X
$ sudo easy_install pip
Installing TensorFlow
# Ubuntu/linux 64-bit, CPU only, Python 2.7:
$ sudo pip install--upgrade https://storage.googleapis.com/tensorflow
The following small series for everyone to bring a TensorFlow installation and Jupyter notebook configuration method. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's take a look at it with a little knitting.

This statement specifies the python runtime environment. There are two ways to specify this method. One is to specify the python path ---#! /Usr/bin/python
1. New environment python3.5 in Anaconda, I am using the new environment in Anaconda-navigator, Python version selection 3.52. Activate the newly added environment, pay attention to win, no source, direct useActivate New_env_name3. Install TensorFlow, reference https://github.com/tensorflow/tensorflow/blob/r1.0/tensorflow
Recently learning TensorFlow, of course, the premise is to install a good framework, many online tutorials are virtual or conda, from my experience, Windows is currently only supported Python3.5 version of the installation, Python official online has instructions:I Python27 because of the commonly used is the change of a bit:Download anaconda2 and install to D:\anacondaDownload Anaconda3: Note The version, the integration must be Python3.5, the latest
The first blog, the main record of the installation of deep Learning Framework (TensorFlow), installed very simple (a word), started I thought it was troublesome, no n card, do not know how to start. Okay, here we are.I generally like the pydev of Eclipse (personal feeling is very useful), then Python is mainly Anconda (Tsinghua Mirror), loading TensorFlow1.

In deep learning, regardless of the learning framework, we encounter an important problem, that is, after training, how to store the depth of the network parameters. How these network parameters are invoked at the time of the test. In response to these two questions, this blog post explores how TensorFlow solves them. This blog is divided into three parts, the first is to explain tensorflow related function
first, to enter the Anaconda website Download
https://www.anaconda.com/download/
Everyone according to their own computer configuration download the corresponding version, I download here is the version of python3.6version 64bit
After downloading and installing, open CMD, enter ' Conda--version ', if output the following information
4.3.21
Anaconda installation was successful.
2. Install TensorFlow

The previous article has introduced the implementation of convolution, this article we learn the deconvolution principle, again, after understanding the deconvolution principle, in the back hand-written Python code to implement the deconvolution. 1 Inverse convolution principle
The deconvolution principle does not work well with text descriptions, where the deconvolution process is described directly in a simple example.
Suppose the input is as follows:
[[1,0,1],
[0,2,1],
[1,1,0]]

3 Ways of reading data
There are 3 ways to read data in a TensorFlow program:Supply data (feeding): At each step in the TensorFlow program, let the Python code supply the data.Reading data from a file: At the beginning of the TensorFlow graph, let an input pipeline read the data from the file.Preload data: Define constants or variables in the
