In hardware course design, after tpc-zk-ii integrated development environment is installed on win10, a pop-up window will display “run time error” 70 “: permission denied.
The solution is as follows:
Find the corresponding “. Exe” file and run it as an administrator.
Run B_ Yolov4 an error is reported when calculating the map:

This happens
Solution: find the following path file, delete the two files indicated by the arrow, and restart Anaconda – the personal test is successful
Change this to the native java version
Project: springboot + Vue
Reason: after the online environment is released, it can’t get into the system. The above error has been reported all the time, and it’s useless to repackage and compile. The original reason is that the front end downloaded a new dependency and didn’t upload the updated version number, resulting in the above error
solution: import the dependencies downloaded from the front end into the local NPM install, submit the package.json file to the online server, and redistribute the version to solve the problem.
Problem: Maven packages UDF functions with stackoverflowerror
solution: set the stack size in idea
[problem phenomenon]
When the springcloud system is built in the idea, a red error is prompted at runtime:
org.springframework.beans.factory.BeanCreationException:

Caused by: java.lang.ClassNotFoundException:

[reason]
This is a very common problem in the spring cloud system because the spring boot version is incompatible with the spring cloud version.
[solution]
The spring boot version and spring cloud version should be matched in strict accordance with the official version. Link to the official website:
https://spring.io/projects/spring-cloud
Different clouds need different boot versions, as shown in the figure:
Example of version change:
after version replacement, reload all Maven items, as shown in the figure:
If an error is still reported, re-execute the MVN clean package

Execute the following commands when upgrading the flutter
Flutter upgrade
Unfortunately, for some reason, it cannot be accessed. The following error is reported
Standard error: fatal: unable to access
'https://github.com/flutter/flutter.git/': LibreSSL SSL_connect:
SSL_ERROR_SYSCALL in connection to github.com:443
You can set the routing agent. The command is as follows:
git config --global http.proxy http://127.0.0.1:1080
git config --global https.proxy http://127.0.0.1:1080
Note that the port can be modified according to its own configuration. Set or not set HTTPS according to your needs
if you want to cancel the proxy setting, you can use the following command:
git config --global --unset http.proxy
git config --global --unset https.proxy
After setting, test OK
Git config — the global command will add the following configuration in the ~ /. Gitconfig file
[http]
proxy = http://127.0.0.1:1080
[https]
proxy = https://127.0.0.1:1080
Note:
there is another way to use this command. It has not been tested yet. Save it first
git config --global --add remote.origin.proxy
