There are three methods for reading Tensorflow data (next_batch ),
Tensorflow data can be read in three ways:
Preloaded data: pre-load data
Feeding: Python generates data and then feeds the data to the backend.
Reading from file: read directly from the file
What are the differences between the three read methods? First, we need to know how TensorFlow (TF)

Enter TensorFlow environment, enter>>> Activate TensorFlowBefore the command line, you can see the Add (TensorFlow) before entering the promptBecame like this
Install TensorFlow (CPU version)Familiar with the Anaconda command, you can refer to http://www.jianshu.com/p/d2e15200ee9bThe official recommendation is that you have the GPU immediately, but you can also install a CPU version, and the command to create the environment is:conda create -n tensorflowpython=3.6(Be sure to specify the Python version, I did not write python=3.6 at first, after various failures)Download the installation package first, the d

Amazon open machine learning system source code: Challenges Google TensorFlowAmazon took a bigger step in the open-source technology field and announced the opening of the company's machine learning software DSSTNE source code. This latest project will compete with Google's TensorFlow, which was open-source last year. Amazon said that DSSTNE has excellent performance in the absence of a large amount of data to train machine learning systems, while
This article mainly introduces the realization method of TensorFlow implement nonlinear support vector machine, and now share to everybody, also make a reference for everybody. Come and see it together.
This will load the iris dataset and create a classifier for the iris (I.setosa).

One day, I installed tensorflow with anaconda and applied it to pycharm ------ installation experience below...1. download Anaconda from the official website. It seems that only version 2.7 is available. When installing Anaconda, check defaultpath so that you do not need to configure the environment variable. Because it is not checked for the first time, it is not installed successfully, always Prompt Conda is neither an internal command nor an extern

Now we all know that Geoffrey Hinton's capsule Network (capsule network) shook the entire AI field, pushing the limits of convolution neural networks (CNN) to a new level. There are already a lot of posts, articles and research papers on the web that discuss the theory of capsule networks and how it does better than the traditional CNN. So I'm not going to introduce the content, but try to use Google's Colaboratory tool to implement Cpnet on TensorFlow
TensorFlow to use, first of all, you have to get the data input. The official documentation describes several of the 1. Read the data from memory to the matrix at once, input directly; 2. The input from the edge of the file is read, and the multithreaded read-write model has been designed; 3. Convert the data in the network or in-memory into the TensorFlow special format Tfrecord, and then read it after the

In the TensorFlow wrote such a sentence:

Where the shape of the outputs [16,336,400],w shape is [400,1]
The following error occurred:
Shape must be rank 2 but are rank 3 for ' Matmul ' (op: ' Matmul ') with input shapes: [16,336,400], [400,1].

Learning Google's deep learning finally a little bit of the prospect, to share my tensorflow learning process.
TensorFlow's official Chinese document is jerky, and the dataset has been used in the Mnist binary dataset. And not much about how to build their own picture dataset Tfrecords.
First paste my conversion code to transfer the pictures under the picture folder to the Tfrecords dataset.
