From the name of TensorFlow can be seen that tensor (tensor) is a very heavy concept. All the data in the TensorFlow program is represented by the tensor form. From a functional point of view, the tensor can be understood as a multidimensional array. The 0-order tensor indic

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

Order, shape, data type of tensor TensorFlow uses this data structure to represent all of the information. You can think of a tensor as an n-dimensional array or list. A tensor has a static type and a dynamic type of dimension. Tensor can flow between nodes in the diagram. Order In the TensorFlow system, The dimension

Common tensor operations1. the tensor. View method can be used to adjust the tensor shape, but the total number of elements before and after the adjustment must be consistent. View does not modify its own data, and returns a new tensor shared memory with the original tensor,

about TensorFlow Computing model TensorFlow's programming differs greatly from the way I used to approach programming. Previous programming, whether the compiler type of language or scripting language, is a step-by-step, variable calculation, you will get results, such as c=a+b, when the execution of the statement, you will get the value of C. But TensorFlow is not, it first to programmatically, build a calculation diagram out, and then enable a session to take the data as input, through the ca

Here, the so-called tensor is different from the tensor In the column. The tensor is more physically used, and this tensor is the extension of the matrix. For example, a zero-order tensor is a number, a first-order tensor is a vec

Oneself through the online inquiry about tensor explanation, a little finishing. TensorFlow uses this data structure to represent all of the information. You can think of a tensor as an n-dimensional array or list. A tensor has a static type and a dynamic type of dimension. Tensor can flow between nodes in the diagram

When debugging a program written in TensorFlow, you need to know what the value of a tensor is. Direct print can only print out information such as the shape,dtype of the output tensor, and the method to view the values of the tensor is as follows: "1" with class TF. Session or Class TF. InteractiveSession class Import TensorFlow as tf x = tf. Variable (Tf.consta

In the process of learning tensorflow, we need to know what the value of a tensor is, which is important, especially at the time of Debug. Maybe you can say, this is easy, just print it. In fact, print only prints output shape information, and to print out the value of the tensor, you need to use class TF. Session, class TF. InteractiveSession. Because we are building graph, we only build

This is tensorflow a recurring error, the cause of the error is that there is not enough memory for the video card.The solution is to reduce the use of memory cards, the way there are several measures:1 Reduce the size of batch2 analysis of the location of the error, at which level of the video card is not enough, such as in the full connection layer appears, then reduce the dimensions of the full connection layer, 2048 to 1042 what3 Increase the pool layer, reducing the overall network dimensio
