Foreword We often encounter input boxes that need to be restricted to numbers. Because the user is outrageous, he insists on entering English or Chinese where the numbers are clearly entered. However, it is more troublesome to use the UI framework or write your own methods to verify the form. It is very troublesome to […]

QT captures keyboard input and displays the input shortcut key combinations, and solves the problem that some key combinations (such as Ctrl+Shift+letters) cannot be recognized in the Linux environment
Recently I am working on a QT project, which requires identifying keyboard input keys to generate shortcut keys. There is a class QKeySequenceEdit in QT. Using this, you can directly obtain keyboard input. However, if you want to filter out the keys you do not want to recognize, you must rewrite it. ThekeyPressEvent(QKeyEvent *e) function. […]
C++ uses boost to implement an asynchronous thread pool with return values and input parameters
Preface Thread pools have some advantages over simple multi-threading: 1. The thread pool will automatically allocate work to an idle worker thread for execution, which is better than multi-thread execution in batches; 2. The thread pool only needs to be created once. The creation and destruction of multiple threads when used multiple times will cause […]
React implements the text box input text content to dynamically add text information (multiple) to the picture and generate a new picture
Article directory Idea 1 Idea 2 1. Download the html2canvas dependency package 2. Build the page and create an area for adding new nodes 3. Initialize and add the first node to a specified module in the page 4. When the text box changes, modify the node information 5. Implement node deletion 6. Use html2canvas […]
Solve the problem of converting pytorch model to onnx model, and the grid_sample function input parameter is 5-dimensional and the export fails
When transferring pytorch to onnx, grid_sample does not have a corresponding operator, so the transfer cannot be successful. The solutions on the Internet are all four-dimensional (4D) data input, but my input is five-dimensional (5D). I looked for the code and made modifications based on some codes. . The code does not consider performance, only […]
[Grain temperature prediction] Genetic algorithm optimization of BP neural network GA-BP grain temperature prediction research (multiple inputs and single output) (including comparison before optimization) [Including Matlab source code 2404]
?1. Genetic algorithm optimization of BP neural network for grain temperature prediction Abstract Aiming at the nonlinear time series problem of temperature parameters in grain storage, a grain temperature prediction model based on genetic algorithm (GA) optimized BP neural network algorithm was proposed, and 10 factors affecting grain temperature were selected (external temperature, external humidity, […]
