A solution to the kernel error of Jupiter notebook in Anaconda under Windows 10

Problem Description:

                After installing Anaconda 3, open the Jupiter notebook to create a new one. When you click Python 3, the kernel error is always displayed. It has been tried several times. I believe many people have such a problem. No matter uninstalling and reloading Anaconda or rebuilding an environment, it has not been solved. Until later, it was found that the nuclear was not cleaned up. Here I share a solution to this problem. Successfully solved my problem.

solve:

1. Open the anaconda prompt window and enter Jupiter kernelspec list to see the location of the current kernel. Note that this is the wrong kernel,

 

2. Copy this address and uninstall the current anaconda

3. Find the address just now and delete the jupyter folder

4. Reinstall Anaconda

It can be solved!!

 

 

SyntaxError: (unicode error) ‘unicodeescape‘ codec can‘t decode bytes in position 2-3: truncated \UX

Open a named PI with absolute path under windows_ The file of digits.txt has an error

Because the resource of the path cannot be found after escape.

To change a \ in the absolute path to\\  

This is the path before the error is reported.

The path that runs successfully after modification.

  Moreover, it can be found that it is not necessary to replace all \ \, replace the front with \ \, and run without changing the back.

SyntaxError: (unicode error) ‘unicodeescape‘ codec can‘t decode bytes in position 2-3: truncated \UX

Error:

When specifying the file path with Python, the error ‘syntax error: (Unicode error)’ Unicode escape ‘codec can’t decode bytes in position 2-3: truncated \ uxxxxxxxx escape’ may occur.

The reason for the error is that “\” is used in a string such as a path, which is treated as an escape sequence. In the windows environment, the combination of ‘\’ and characters represents an escape sequence. Python provides escape sequences including \\(backslash) and \n (line spacing).

Generally speaking, the path is as follows:

C:\Users\Desktop\myproject

 

Solution:

Windows：

Use the escape sequence “\\” representing the backslash (on windows\), as follows:

C:\\Users\\Desktop\\myproject

Unix:

Use “/” to separate directories

C:/Users/Desktop/myproject

Error in installing paddlenlp on pip on Windows

1. PIP installation paddlenlp reports an error

An error is reported when PIP installs paddlenlp on windows, as follows:

 distutils.errors.DistutilsError: Command '['C:\\Users\\yuanyangping\\.conda\\envs\\yyp_paddle\\python.exe', '-m', 'pip', '--disable-pip-version-check', 'wheel', '--no-deps', '-w', 'C:\\Users\\YUANYA~1\\AppData\\Local\\Temp\\tmphix_2c5i', '--quiet', 'setuptools_scm']' returned non-zero exit status 1.

Some methods to solve the problem are queried, but they are not effective, so they are not listed one by one.

2. Solutions

Pay attention to one detail. It is normal to download paddlenlp, but an error is reported only after downloading seqeval, as follows:

Collecting paddlenlp
  Downloading http://mirrors.aliyun.com/pypi/packages/b0/7d/6c24cda54d018d350ee342f715523ade7871660444ed95f3d3e753d6f388/paddlenlp-2.0.8-py3-none-any.whl (571 kB)
     |████████████████████████████████| 571 kB 467 kB/s
Collecting seqeval
  Downloading http://mirrors.aliyun.com/pypi/packages/9d/2d/233c79d5b4e5ab1dbf111242299153f3caddddbb691219f363ad55ce783d/seqeval-1.2.2.tar.gz (43 kB)
     |████████████████████████████████| 43 kB 656 kB/s
    ERROR: Command errored out with exit status 1:
     command: 'C:\Users\yuanyangping\.conda\envs\yyp_paddle\python.exe' -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'C:\\Users\\YUANYA~1\\AppData\\Local\\Temp\\pip-install-n4_d0gwa\\seqeval_6f8ecdc805df4aa092ecc3df7994196f\\setup.py'"'"'; __file__='"'"'C:\\Users\\YUANYA~1\\AppData\\Local\\Temp\\pip-install-n4_d0gwa\\seqeval_6f8ecdc805df4aa092ecc3df7994196f\\setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' egg_info --egg-base 'C:\Users\YUANYA~1\AppData\Local\Temp\pip-pip-egg-info-zp58k0dh'

Therefore, can you install seqeval first and then paddlenlp, and execute two commands in succession, as follows:

pip install seqeval
pip install paddlenlp

Then paddlenlp is successfully installed
If an error is still reported, specify the version of seqeval as 0.0.3

3. Extension

The above reason should be that there is a problem with the configuration information when downloading and installing seqeval
therefore, if similar error reports occur when installing other software, you can install the software where the error is reported first, and then install the main software you want to install.

Error 3 error C2065: ‘endl‘ : undeclared identifier-Error 2 error C2065: ‘cout‘ : undeclared identif

As you can see, I just want to print something, and iostream is added, but that means I cout can’t use it.

hold   If StdAfx. H is placed at the front of the whole file, no error will be reported

In fact, if other header files are mentioned to the front, an error will be reported – this may be the provision of VS2010,   StdAfx. H must be first.

 

Even if you comment it out   All include in StdAfx. H are commented out. Whether the compilation passes or not.

 

 

The vscode installation plug-in liveserver specified browser reported an error and could not be found

Problem Description:

After installing vscode, you do not want to use the default IE browser. You want to specify chrome or Firefox, but install the plug-in lever server or other browser plug-ins. When specifying the default browser, windows reports an error and cannot find chrome or Firefox
after reading many posted on the Internet, they are configured in settings.json. After personal practice, they have no effect. Later, after their own exploration, they found that the plug-in can’t find your chrome or Firefox. It’s not that you haven’t installed it on your computer, let alone on disk C; But because when a plug-in such as lever server specifies a browser, the windows system will find the installation directory of the software according to the system variables.

terms of settlement:

1. Open the control panel of the computer – & gt; System and security —– & gt; System
2. Open advanced system settings, click environment variables, system variables, and add a new variable named path: D: \ Kiki \ Mozilla Firefox
this directory is the directory where your Google or Firefox exe files are located
3. After configuring environment variables and saving, restart vscode
