ERROR 1045 (28000): Access denied for user’ODBC’@localhost (using password: NO)209150;’211503;’

Sometimes, due to carelessly forgetting the password or installation errors, the following errors will be reported when running MySQL:

ERROR 1045 (28000): Access denied for user ‘ODBC’@‘localhost’ (using
password: NO)

According to the solution on the Internet:
or modify the configuration file my.ini

skip-grant-tables

To skip password verification
or: edit my.cnf,

But the above is useless. After trying to spit blood, I found that I could not even start MySQL service by modifying the configuration file, but so on….. Isn’t there a landing<
after clicking , I found that I can change the password directly here

change the password to my own setting, I set it to 123456, log in again, success

Error:Kotlin: Module was compiled with an incompatible version of Kotlin. The binary version of its

Once a project encountered an error before starting compilation: E rror:Kotlin : Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.13.

Module is compiled with an incompatible version of kotlin.

But I have never encountered any problems, and no similar solution has been found on the Internet.

Later, I tried many ways, but I restarted the plug-in

You can cancel it and check it again, and then restart the project.

nginx: [error] invalid PID number ““ in “/data/nginx/logs/nginx.pid“

After modifying the configuration file, nginx: [error] invalid PID number “” in/data/nginx/logs/nginx. PID “appears during restart. This means that a valid PID (process number) cannot be found in the file/data/nginx/logs/nginx. PID

Solution 1: find the PID of nginx’s main process number, write it into nginx.pid file, and restart nginx

[root@yzil ~]# nginx -s reload
nginx: [error] invalid PID number "" in "/data/nginx/logs/nginx.pid"
[root@yzil ~]# ps aux | grep "nginx: master" | grep -v pts | awk '{print $2;}'
2847
[root@yzil ~]# ps aux | grep "nginx: master" | grep -v pts | awk '{print $2;}' > /data/nginx/logs/nginx.pid
[root@yzil ~]# nginx -s reload
[root@yzil ~]#

Solution 2: kill the nginx main process and restart nginx

[root@yzil ~]# killall nginx
[root@yzil ~]# nginx

 

Vs error unresolved external symbol_ Main, the symbol in the function “int”__ cdecl invoke_ main

Cause analysis

There are many reasons for this problem. The first and most common one is that there are multiple CPP files in your project, which contain multiple main functions
the second is that your code is copied from QQ or other ways (such as Notepad). In this case, the newline character may change. According to the explanation of the online boss, the newline character has many codes. If the format is wrong, there will be problems. At this time, you will be prompted to convert the source file to DOS or UNIX format, If there is a warning, it means that you are in this situation. You need to find the advanced save option in the file menu of vs (the advanced version needs to be called out in the settings, but not Baidu search), and then select window (CR LF), which means that the new line character supported by the window system indicates that the problem is solved ~
the third is that your project is created incorrectly, If your compiler’s preprocessor is not right, you can copy the code directly to the new correct project, or open the project settings and modify your preprocessor. You can search for it.

Opencv (4.5.1) error: assertion failed (((npoints > = 4) | (npoints = = 3 & & flags = = s)

Solve the problem of solvepnp (outdim, indim, cameramatrix, distcoeff, RVEC, tvec); There is an unhandled exception at 0x00007ffbc3844b89 (in biaoding.exe): Microsoft C + + exception: CV:: exception, in the memory location of 0x000000571351b2d0
 
Mapping 3D point cloud to 2D image, using OpenCV solvepnp, running error

OpenCV(4.5.1) Error: Assertion failed (( (npoints >= 4) || (npoints == 3 && amp; flags == SOLVEPNP_ ITERATIVE && amp; useExtrinsicGuess) || (npoints >= 3 && amp; flags == SOLVEPNP_ SQPNP) ) && amp; npoints == std::max(ipoints.checkVector(2, CV_ 32F), ipoints.checkVector(2, CV_ 64F))) in cv::solvePnPGeneric, file C:\build\master_ winpack-build-win64-vc15\opencv\modules\calib3d\src\solvepnp.cpp, line 802

The error is as follows:

The input coordinates of 3D point cloud and 2D pixel are:

Conversion type:

After the conversion, the output of outdim and indim is changed, and it is no longer a 6 * 3 matrix, so an error will be reported

So the error is because the matrix dimensions in solvepnp are inconsistent. The solution is to use push again in the most stupid way_ Back redefines outdim and indim, instead of using for loop to define outdim and indim, just in case cameramatrix is also redefined

Finally, the rotation translation matrix from radar to camera and the result map of point cloud mapping to image are obtained

Most of the answers on the Internet are about. Htaccess, but I don’t think there’s anything wrong with local HTaccess:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond   %{REQUEST_FILENAME} !-f
    RewriteRule   ^(.*)$ index.php?_url=/$1 [QSA,L]
</IfModule>

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteRule  ^$ apg/public/    [L]
    RewriteRule  (.*) apg/public/$1 [L]
</IfModule>

The url is correct

http://127.0.0.1/MyProject/login/userLogin

But the page doesn’t display the right content.
Let me see where the framework needs to be changed. I still think the framework hasn’t changed.
Solutions:
Later, I checked my collection.php, and there was an array in it, and I added the name of MyProject MyProject:

 static private $ProjectsArray = array(
            'project1',
            'project2',
            'project3',
            'MyProject'
);

The problem solved! Check my localhost page again and you can visit my Project login page. The framework has been set up successfully!
