Executes the diagram in the context of what is referred to as a conversation (session). Use tensor (tensor) to represent the data. Maintains state through variable (Variable). Use feeds and fetches to assign values to or fetch data from any operation (arbitrary opera

Keras mixed with TensorFlow Keras and TensorFlow using tensorfow Fly Keras
Recently, TensorFlow has updated its new version to 1.4. Many updates have been made, and it is of course important to add Tf.keras. After all, Keras for the convenience of the model building everyone is obvious to all.

Always keep abreast of the times and the pace of technology-machine learning will eventually change our lives, study and work, perhaps in the near future.Today, I am ready to try to build a learning environment based on my big Google TensorFlow, which day may be able to teach it to play games, or can assist in the game development to build some interesting levels, first do accumulate and cultivate interest it. Well, the nonsense is not much to say, ge
1. Introduction
Comparison and Analysis of differences between TF. Variable/TF. get_variable | TF. name_scope/TF. variable_scope
2. Description
TF. Variable: create variable; TF. get_variable: Create and obtain variable
TF. Variable automatically detects and processes name conflicts. TF. get_variable reports an error when reuse is not set.
TF. name_scope does not have the reuse function. TF. get_variable returns an error in variable conflict. TF. variable_scope has the reuse function, which

TensorFlow implements RNN Recurrent Neural Network, tensorflowrnn
RNN (recurrent neural Network) recurrent neural Network
It is mainly used for natural language processing (NLP)
RNN is mainly usedProcess and predict sequence data
RNN is widely used in speech recognition, language model, and machine translation.
The source of RNN isDepicts the current output of a sequence and the previous information that affects the output of subsequent nodes.

1.Build Docker ImageBecause you always have problems with your build image, here is a temporary lease on a mirror on Dockerhub docker.io/mochin/tensorflow-servingPush this image to the Docker registry of the K8s cluster2. Writing YamlIn the official example, a yaml is given, but some places are wrong, or the dockerimage is not applicable (probably because of the 0.4.0 version)Made some changes.Apiversion:extensions/v1beta1kind:deploymentmetadata: nam
mainstream framework, of course, not to say that Keras and CNTK are not mainstream, the article does not have any interest related things, but the keras itself has a variety of frameworks as the back end, So there is no point in contrast to its back-end frame, Keras is undoubtedly the slowest. and CNTK because the author of Windows is not feeling so also not within the range of evaluation (CNTK is also a good framework, of course, also cross-platform, interested parties can go to trample on the
With so long a tensorflow, the example ran n many, the basic flow is clear. But to do a small example of their own independence has come all sorts of questions. Like your own picture data set how to do. To tell the truth, TensorFlow is really annoying, the management of the document tutorial old mnist and cifar_10 this good data set said, for us beginners, completely do not know how to enter the picture. To
Let's say we've installed the TensorFlow.
Generally in the installation of good TensorFlow, will run its demo, and the most common demo is handwritten digit recognition of the demo, that is, mnist data set.
However, we just ran its demo, maybe a lot of people will have the same ideas as I do, if you bring a digital picture, how to use our training network model to identify, the following we will be Mnist de

TensorFlow in a Python environment, the easiest way to do this is to use the ANACONDA3 integrated environment for installation.
First of all, download the anaconda3,3.6 version or version 2.7 of the Python version in the Anaconda3 website.
You do not need to install the Python direct install Anconda3 beforehand, will automatically install the corresponding Python.
After the Anaconda installation is successful, we need to modify its package mana
After training a good network, it is important to retrain and predict later. So this article is mainly about if the storage of good parameters and the use of well-trained parameters.The main APIs usedHttps://www.tensorflow.org/api_docs/python/tf/train/Saver
The following example illustrates that the network is to construct a convolutional neural network for handwritten numerals to identify.

The adience data set is from Flickr, which is used by users on the iphone or other smartphone devices, and is primarily intended for unfiltered face estimation of age and gender. At the same time, the corresponding landmark is also labeled, which contains 2,284 categories and 26580 im
Issues encountered in installing tensor flow after the PIP package and Python have been installed:
First, the default is the foreign mirror source, so limited, can cause errors or download speed is very slow. So look for a domestic Python image source (address: http://blog.csdn.net/yywan1314520/article/details/51045660).
Second, the following error occurred in the installation because it was not added to a trusted address.
Could not find a version this satisfies the requirement
Use the graph (graphs) to represent the calculation task, the node in the graph is called Operation OP (Operation). Each diagram represents its own calculation task. The TensorFlow Python library has a default diagram, and the first step in the start diagram is to create a session object, and if there are no parameters to create, the session builder starts the default diagram. The OP constructor can add nodes to it. Most of this default diagram is eno
