First of all, I met this error report

>>> import WindPy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: source code string cannot contain null bytes

It’s probably the coding problem. The solution is to use vscode to open windpy.py (just search in the computer). There is a coding button in the lower right corner. Now the UTF-8 is displayed. Originally, it seems to be utf-16le. The Chinese displayed in the text is still garbled. Click this button and select save in this format.

And then there’s the following error report

SyntaxError: 'gbk' codec can't decode byte 0xbd in position 2985: illegal multibyte sequence

The solution is to delete all the comments.

It’s the last mistake.

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\**myfiles**\\Python\\Python38\\site-packages\\WindPy.pth'

The solution is to look for open in windpy.Py and comment all the following lines

Change the line that reads the library to the address of windpy.dll

    # pathfile=open(sitepath)
    # dllpath=pathfile.readlines();
    # pathfile.close();

    # sitepath=dllpath[0]+"\\WindPy.dll" 

    c_windlib=cdll.LoadLibrary('D:\\**install_WIND_files**\\x64\\WindPy.dll')

Just fine. I hope I can help you not to fall into the pit
