Brief introductionPrevious note: TensorFlow study notes 1:get Started We talked about TensorFlow is a computing system based on graph. The nodes of the graph are made up of operations (operation), and each node of the graph is connected by tensor (Tensor) as an edge. So TensorFlow's calculation process is a tensor flow graph. The TensorFlow diagram must be calcul

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)

TensorFlow TensorFlow (Tengsanfo) is Google based on the development of the second generation of artificial intelligence learning system, its name comes from its own operating principles. Tensor (tensor) means n-dimensional arrays, flow (stream) means the computation based on data flow diagram, TensorFlow flows from one end of the flow graph to the other.
TensorFlow implements the Softmax regression model, tensorflowsoftmax
I. Overview and complete code
Tensorflow encapsulates MNIST (MixedNational Institute of Standard and Technology database), a very simple machine vision dataset, and can directly load MNIST data into the expected format. this program uses Softmax Regression to train the classification model for Handwritten Digit Recognition.

My computer did not install a dual system, so decided to install a tensorflow in the virtual machine, the following is the installation process:1.

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.
