Solve python error UnicodeDecodeError: utf-8 codec cant decode byte 0xff in position 0: invalid start byte

Resolve the error UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0xff in position 0: invalid start byte

Reason for the error:
I saved the generated image file and the csv data file in the same directory, which led to reading the jpg file when I continued the walk. Of course, it cannot be read in utf-8 format

Workaround:

1. (recommended) Add a judgment condition to the read file, such as using split to judge the file suffix

 for root,dirs,files in os.walk(indir+'/'+user):for f in files:if f.split('.')[1span>] == 'csv':#TODO

2. The generated files are saved in other directories. This method is essentially to ensure that the files in the source directory are all the data files we want to read, excluding other types of files
