tensorflow udacity

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

1. Import tensorflow Import tensorflow as TF Ii. Define a computing Diagram (1) constant Initialization Constant_name = TF. Constant (value) (2) variable Initialization Create variable: Name_variable = TF. Variable (value, name) Initialization of individual variables: Init_op = name_variable.initializer () Initialize all variables: Init_op = TF. global_variables_initializer () Note: If the variable type is

After you install TensorFlow, open a Python environment and start running and using TensorFlow.First give an instance,#先导入TensorFlowImport TensorFlow as TF# Create TensorFlow object called Hello_constantHello_constant = Tf.constant (' Hello world! ')With TF. Session () as Sess:# Run The tf.constant operation in the sessionOutput = Sess.run (hello_constant)Print (

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. RNN isC

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

Floor, fully connected layer The number of input nodes in this layer is 120, the number of output nodes is 84, the total parameter is 120*84+84=10164. seventh floor, fully connected layer The number of input nodes in this layer is 84, the number of output nodes is 10, and the total parameters are 84*10+10=850 tensorflow implementation LeNet-5 The following is a TensorFlow program to implement a convolution

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. https://github.com/xgli/TensorFlow-Examples/blob/master/examp

This post uses TensorFlow as an exercise to infer the age and gender of photos based on the face, and there are many similar apps online. Training Data –adience data set 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

Download and install AnacondaDownload the anaconda first, which can be downloaded from the image website of Tsinghua University .Install Anaconda, and be careful not to remove the option to add environment variables during installation.After the installation is complete, in the installation directory cmd, enterConda ListYou can see the integration environment that Anaconda provides for us:Here's just a part:To view version information:Conda--versionAnaconda installation was successful.Next need

In the previous article, "TensorFlow load pre-training model and save Model", we learned how to use the pre-training model. Note, however, that in the previous article, you must have at least 4 files to use the pre-training model: Checkpoint Mymodel.meta mymodel.data-00000-of-00001 mymodel.index This is very inconvenient for us to use. Is there a way to export a PB file and then use it directly. The answer is yes. In the article "

First to install the Anaconda.Note that to add an environment variable to the system, there is an option for this. Or you'll need to manually CD to Anaconda3\bin to execute the instructions below. Due to the installation of TensorFlow, use Pip Install TensorFlow The instructions always go wrong, even with the official website. Pip Install--upgrade HTTPS://STORAGE.GOOGLEAPIS.COM/

November 29, 2016, TF officially announced that version 0.12 TensorFlow supports native Windows operating systems and is not installed through Docker. TF beginners, Windows heavy dependent users, can follow the following feasible installation method. First, install Python 1. Install Python on Windows via pip TensorFlow only supports 64-bit Python3.5on Windows, either via Python 3.5 from python.org or Pyth

On the internet to find a lot of cases, stepped on a lot of pits, feel more comprehensive is the following introductionHttp://www.cnblogs.com/xuliangxing/p/7575586.htmlLet's talk about my steps:First installed the Anacoda, because it is a scientific computing environment, so first installed the latest version, so the corresponding Python 3.6Install graphics driver: gtx950m installed the latest 390 drivers, worried about incompatibility, so all with the latestInstalling Cuda, this pit was finally
