Error reporting reason

    import win32api
ImportError: DLL load failed: The specified program could not be found.

This is caused by the incompatibility between the python version and the pywin32 version.

Solution:

Reinstall the latest version of pywin32 = = 301 in the TF2 environment with CONDA error. Solution: CONDA install pywin32 = = 301

Vue Uncaught (in promise) Error: Navigation cancelled from “/home“ to “/login“ with a new navigation

Sublime text4 install package error [How to Solve]

Problem introduction

sublime Text4 when installing install package control , you may encounter the following errors:

an error occurred installing package control.
Visit https://packagecontrol.io/installation for manual instructions

Problem-solving

For the above problems, it may be due to network problems. At this time, try adding the following two lines to the hosts file.

50.116.34.243 sublime.wbond.net

Parsing error: await is a reserved word [How to Solve]

Problem: the error message is that a red wavy line appears in the editing of vscade. When the mouse is placed, it will prompt: parsing error: await is a reserved word. Parsing error: await is a reserved word, indicating that the editor does not recognize it and takes it as a keyword

Because an async keyword is added to the function outside the form verification, you want to write synchronization code in the callback function, but an error is reported.

// save
async save() {
  this.$refs.form.validateForm((valid) => {
    if (valid) {
      // The purpose of adding await is to wait for the save to complete before refreshing the list
      await /* this async reports an error */ this.saveRecord()
      this.$emit('closeModal')
      this.reset()
    }
  })
}

After modification:

save() {
// The async should be defined in front of the callback function (anonymous function) at this point.
// The external function and the callback function form two separate scopes.
// The function defined externally and the callback function form two block scopes,
// At this point, await and aysnc are not in the same scope, so they cannot be paired and an error is reported
 this.$refs.form.validateForm(async (valid) => {
   if (valid) {
   	 // The purpose of adding await is to wait for the save to complete before refreshing the list
     await /* No error is reported here for async */ this.saveRecord()
     this.$emit('closeModal')
     this.reset()
   }
 })
}

Summary: if you want to write synchronization code inside the callback function, you need to put the async keyword in front of the callback function to make async and await in the same scope

[Solved] Whitelabel Error PageThis application has no explicit mapping for /error, so you are seeing this

Problem Description:

Bloggers appear when running springbootweb:

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

As follows:

It is found that the input URL is incorrect. After repeatedly confirming that the path in the file is written correctly, it is found that the location of the main running class of springboot is incorrect:

i see:

The package name was set when the springboot was created, but the self tested controller is in another self created package, but the spring boot will automatically load all components under the package where the startup class is located and its sub packages, so an error is reported

Solution:
just put the WebTest package on com.web.springboot_ Just under echarts

The purpose is to make the application contain all sub packages!!

How to Solve Docker delete container image error: Error response from daemon: conflict: unable to delete 7cc1942f1ed5 (must be forced)

I don’t know if you have encountered an error when
docker deletes the container image

docker RMI container image ID

Details of error reporting:

Error response from daemon: conflict: unable to delete 7cc1942f1ed5 (must be forced) – image is referenced in multiple repositories

Solution:

First docker PS - a
see several containers with the same image ID. what the hell, There must be a mistake during the construction, and then stop the container using the container image (if it has stopped, please go to the next step)
docker stop the ID of the container using the container image and RM drop
docker RM the ID of the container using the container image and
docker RMI the container image ID

Discovery or error

Well, the ultimate solution (that’s the point of this article)

docker rmi -f This container image ID

It is the above command with the – f parameter that forcibly deletes all container images with the container image ID

Redis Startup Error: Creating Server TCP listening socket 127.0.0.1:6379: bind: No error

Today, the redis service started in the window and reported an error:
Creating server TCP listening socket 127.0.0.1:6379: bind no error

The reason is that redis did not shut down normally after it was started;

The solution is as follows: enter the following commands in order to connect successfully

redis-cli.exe
shutdown
exit

Redis closes normally, exits, and then re-enter the command to start
redis-server.exe redis.windows.conf

OK！

[Solved] Segyio Error: Runtime Error trace count inconsistent with file size, trace lengths … #401

Article catalog

Run segyio to read segy files and report errors. Troubleshooting error cause reference

An error occurs when running segyio to read the segy file

"RuntimeError: trace count inconsistent with file size, trace lengths possibly of non-uniform"

Solution:

(1) Add: endian ='little '

with segyio.open('test.sgy','r',ignore_geometry=True,endian='little') as f:

(2) If it still fails:
check the length of the data trace. Segyio’s default trace has the same number and format of sampling points. If the length of the trace in the segy file is inconsistent, it may lead to reading errors.

Error reason

Detailed explanation of big endian and little endian
the default bytes of files read by segyio are encoded according to big endian, while your files are written according to little endian bytes

Error 1 error MSB3721: Command ““C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\bin\nvcc.exe” -genco

（cuda9.0targets 707)

Windows10 + cuda9.0 + cudnn + visual stdio2015 (originally, visual stdio2017 was used. Some blogs said no and changed it. If you downloaded 2017, you can directly change it at the change place. A single component will be OK under 2015. Some blogs talked about it and you can search it)

My computer graphics card version is gtx1050

After query, I changed compute and SM to compute_30,sm_30; compute_61,sm_ But it seems useless, but some bloggers say it’s useful, mainly because of different mistakes. You can try it.

I set the CUDA toolkit custom dir to C: \program files\NVIDIA GPU computing toolkit\CUDA at the beginning. When I opened the file, I found an error. It needs to be set to C: \program files\NVIDIA GPU computing toolkit\CUDA\v9.0

Then it’s solved. It’s been busy for two days. I’ve read a lot of blogs. I hope it can inspire you!!!
