actually executes the imported module once, as follows:First look at the module being called test.py :def haha(): print("哈哈")haha()Look at the main program again main.py :import testprint("一条鱼")The execution results are:哈哈一条鱼How can you simply invoke the code without executing the called module? To be called module code is not executed, the premise is to know __name__ what the variable means, in short, if not involved in the module import, __name__ The value is " __main__ ", if the module is

, and a few menus for reporting. As shown in figure: Let's take a look at some of the features of Performance Monitor: Windows Performance Monitor uses performance counters, event trace data, and configuration information that can be merged into a data collector set. Performance counter: A unit of measurement that is a system state or activity condition. They can be included in the operating system or as part of an individual application. Windows Performance Monitor requests the c

In the process of Finereport this report software, it is often necessary to use the function is data analysis. And how the complex data, collation analysis, so as to draw clear findings, it is our learning Finereport the key to this software. The following small series for everyone to share the Finereport report how to data visualization analysis, I hope this tutorial can help everyone! 　1. b/S data source configuration Start the Web server (the FR

Related library: WINSTON,TK. Features: Pure Julia to build, rare, hehe. Basic functions of back-Test visualization: It is easy to see the date of day trading in each transaction point, the day of each profit and loss situation. Do not go to the market to find and control, that too hard. With this analysis tool, we can greatly improve the efficiency of the analysis of the flow of the back-test transaction. It can be used in front of the pan or back. Yo

Visual Description In the previous blog hog principle and OPENCV implementation, we explained the principle of hog algorithm. The final feature is a string of vectors, and we don't know exactly what it looks like, or whether it can reflect the difference between the target area and the non-target region. To solve this problem, we need to visualize the hog feature.The Hog feature first calculates the gradient of each pixel, then creates a sliding window, creates a sliding block in the sliding wi

Description of Error Visualization summary problemWhen doing watermark work, the error between the original model and the watermark model needs to be measured. In order to see the error size more intuitively, the error can be visualized. is an example of a visual error, where the model on the left is the original Model A, the second line on the right is the approximate model of the original model given by an algorithm, and the third line on the right
