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

Google hosted the first TensorFlow developer summit in Mountain View, California, February 16, 2017 (Beijing time) 2 o'clock in the morning. Google site announced the world's leading deep learning open source Framework TensorFlow officially released the V1.0 version, and to ensure that Google's current release API interface to m
Tensorboard Visualization Technology: It introduces how to use Tensorboard, and TensorFlow graph model, training data visualization and so on.
TensorFlow High-level API: Describes the use of layers, estimators, and canned estimators API to define the training model.

Tf.variable_scope () and Tf.get_variables () interface. To ensure that each variable has a unique name and can easily modify the number of hidden nodes and the number of network layers, we recommend referencing the code in the project, especially when defining variables to bind Cpu,tensorflow using the GPU by default may cause parameter updates to be too slow.
The code above is also common in production e
As a result of the recent busy, until the holidays are empty, so will learn from their own knowledge to share. If there is a wrong place, please point out, thank you! At present the deep study is getting more and more fire, the related worker who learns, uses TensorFlow more and more. Recently, a Python script was used to train the model under the TensorFlow line, and the Freeze_graph tool was used to outpu

TensorFlow and tensorflow
Overview
The newly uploaded mcnn contains complete data read/write examples. For details, refer.
The official website provides three methods for Tensorflow to read data:
Feeding: each step of TensorFlow execution allows Python code to supply data.

software environment used in the study. For the last 4 years, open source software Torch7, the machine learning Library, has been our primary research platform, combining the perfect flexibility and very fast runtime execution to ensure rapid modeling. Our team is proud to have contributed to the open source project, which has evolved from the occasional bug fix to being the core maintainer of several key modules. With Google ' s recent open source release oftensorflow, we INITiated a project t
TensorFlow is a deep learning package developed by Google and is currently only supported on Linux and OSX. But this fall may have a Windows-enabled version of it, so for developers who use Windows, there's no need to wait for the fall or go to Linux and OSX TensorFlow. There are two ways to run on Windows, one is to install the virtual machine and install the Ubuntu system, install
TensorFlow can identify the image files that can be used via NumPy, using TF. Variable or tf.placeholder is loaded into the tensorflow, or it can be read by a function (Tf.read), and when there are too many image files, the pipeline is usually read using the method of the queue. Here are two ways to generate TensorFlow image formats, which provide input and outpu
TensorFlow Neural Network Optimization Strategy Learning, tensorflow Network Optimization
During the optimization of the neural network model, we will encounter many problems, such as how to set the learning rate. We can quickly approach the optimal solution in the early stage of training through exponential attenuation, after training, the system enters the optimal region stably. For the over-fitting probl
