DevC++ Error: [Error] Id returned 1 exit status [How to Solve]

DEVC + + reports an error [error] ID returned 1 exit status

Cause

The computer in the school computer room always compiles twice and always reports errors

Error reporting prompt

[Error] Id returned 1 exit status

Solution

Premises

First check whether the console window of your program is closed, and then recompile if there is an error. The following scheme is for the case where an error is still reported after closing the window.

Operation

Right click dev C + + icon -> Properties – > Compatibility > Check “run this program as an administrator” open dev C + + –> tools –> compilation options –> code generation/Optimization –> connector –> set “link objective C program” to yes, and switch the compiler in the upper right corner of the dev C + + main page to debug mode (for example, tdm-gcc 4.9.2 64 bit debug) If your computer has a restore card, please place the project and its files on an unprotected disk.

Python: How to Solve multiprocessing module Error in Windows

[problem description]

The following code can run normally in Linux, but an error is reported in windows.

import multiprocessing

def fun():  # Child process function
     print("child process execution")

p = multiprocessing .Process(target=fun) # Create process object

p.start() # Start the process

p.join() # Recycle process


[solution]

Add code as prompted:

if __name__ == '__main__':
    multiprocessing.freeze_support()

Adding only the above code will still report an error (the same error).

The code for creating process objects, starting processes, and recycling processes should also be placed in __ main__ protection

import multiprocessing

def fun():  # Child process function
     print("child process execution")

if __name__ =='__main__':
     multiprocessing.freeze_support() # Doesn't seem to be added?

     p = multiprocessing.Process(target=fun) # Create process object

     p.start() # Start the process

     p.join() # Recycle process

Done.

Open the link and click the download generation tool:

you will download a tool called vs_ buildtools__ 396764696.1636620081.exe , double-click the executable to download and install the library. Note that the following components are selected during the download process:

Error reported when Windows builds docker image: failed to create LLB definition: 403 Forbidden

preface

Use the docker build command to build a mirror: “failed to solve with frontend dockerfile. V0: failed to create LLB definition: unexpected status code [manifests 18.04]: 403 Forbidden”. The specific screenshot of the error is as follows:

resolvent

It happens during the build process. It is an error in the buildkit, considering that the buildkit is still unstable. If you use the docker desktop on MAC/windows, you may also have to disable it in the “docker engine” JSON configuration
docker desktop – & gt; Settings – & gt; Docker engine – & gt; “Features”: {buildkit: true} will “features”: {buildkit: false}

Note that this is not a fix, it is a solution until someone in the docker team implements the correct fix. Please try again when the buildkit is more stable
