Git Error : fatal: refusing to merge unrelated histories (with github)

Github git push error

 

Error list :

error: failed to push some refs to 'github.com:id/AutoTrade.git'

fatal: refusing to merge unrelated histories

 

command for issue )

git pull origin master --allow-unrelated-histories

 

This command option is used to store the history of a project that already exists. In other words, git basically rejects when merging two heterogeneous projects that do not have related records.

I think it got twisted somewhere because I repeated git add and git init.

The conclusion is solved.

 

 step )

kw@ig-ui-MacBookAir autotrade % git init

kw@ig-ui-MacBookAir autotrade % git remote add origin git@github.com:id/AutoTrade.git

kw@ig-ui-MacBookAir autotrade % git add .

kw@ig-ui-MacBookAir autotrade % git commit -m "first"

 

 

Error 1) error: failed to push some refs to 'github.com:id/AutoTrade.git'

error: failed to push some refs to 'github.com:id/AutoTrade.git'

hint: Updates were rejected because the tip of your current branch is behind

hint: its remote counterpart. Integrate the remote changes (e.g.

hint: 'git pull ...') before pushing again.

hint: See the 'Note about fast-forwards' in 'git push --help' for details.

 

I didn't "git pull", so I think this issue occurred.

 

So, I did "git pull". -> Error 2 Step

 

Error 2) Merge made by the 'recursive' strategy.

… "git pull" is not executed… what the issue….

Python Error : read excel file(included xlsx, ...)

 An internal security tool caused a problem because xlsx was locked into a security program.
In conclusion, the following method was used, but it could not be solved.

error handling step...

code : occurred openpyxl error  

< zipfile.BadZipFile: File is not a zip file >

import openpyxl

 

if __name__ == "__main__" :

    wb = openpyxl.load_workbook("contents.xlsx")

    print(f"{wb}")

error

zipfile.BadZipFile: File is not a zip file

The following methods were used to solve this problem caused by in-house security tools.

step 1. encoding error 

< UnicodeDecodeError: 'cp949' codec can't decode byte 0xf0 in position 20: illegal multibyte sequence >

import openpyxl

import xlrd #add

if __name__ == "__main__" :

    file = open("contents.xlsx","r")

    wb = xlrd.open_workbook(file_contents=file.read()) #add

    print(f"wb")

 

error

wb = xlrd.open_workbook(file_contents=file.read())

UnicodeDecodeError: 'cp949' codec can't decode byte 0xf0 in position 20: illegal multibyte sequence

step 2. encoding error : add utf-8

< TypeError: an integer is required (got type str) >

import openpyxl

import xlrd

if __name__ == "__main__" :

    file = open("contents.xlsx","r", "utf-8")

    wb = xlrd.open_workbook(file_contents=file.read())

    print(f"wb")

 

error

file = open("contents.xlsx","r","utf-8")

TypeError: an integer is required (got type str)

must be specified Encoding type like "utf-8" as "python2 -> python3".

step 3. ???
< TypeError: an integer is required (got type str) >

import openpyxl

import xlrd

if __name__ == "__main__" :

    file = open("contents.xlsx","r", encoding="utf-8")

    wb = xlrd.open_workbook(file_contents=file.read())

    print(f"wb")

 

error

file = open("contents.xlsx","r", encoding="utf-8")

TypeError: an integer is required (got type str)

"utf-8-> encoding="utf-8"

It still hasn't been resolved.
Does anyone know how to read the Excel file that was locked due to the security tool?

</qresource>

</RCC>
-----------------------------------

3. execute command in terminal (in workspace included qml files)
 $ pyside2-rcc -o resource.py resource.qrc

How to remove a square box from a blog post. (with chrome)

ISSUE:
When you read a blog post with chrome, there's an issue where a square box.

Description:

There is an issue in which a square box appears in a blog post as follows.

This issue is only visible to Chrome users and is not a blog problem or a problem with the text itself.

This issue is due to the chrome extension plug-in currently running by the reader.
It is said that a square box can be seen if there is an extension related to the pop-up or a pop-up during the chrome extension plug-in.

In my case, the issue occurred due to "Google translation" plug-in.
Therefore, the issue is solved by shutting down the plug-in or using other Internet Explorers (explorer, edge, safari, etc.).

How to check variant type in C++

 C++ example:

#include <typeinfo>
#include <iostream>
int main() {
int nInt;
char cChar;
std::cout<<"nInt type = " << typeid(nInt).name() <<std::endl;
std::cout<<"cChar type = " << typeid(cChar).name() <<std::endl;
return 0;
}
if you define #include <typeinfo>, you can know type info of the variant.
