UnicodeDecodeError: 'gbk' codec can't decode byte 0xa1 in position 1716: illegal multibyte sequence

This error occurs when Python tries to decode a byte string using the 'gbk' codec, but encounters a byte sequence that is not valid for this codec. In this case, the byte sequence is 0xa1, which is not a valid character in the GBK encoding.

To fix this error, you can try changing the encoding to a different one that supports the characters in the string. For example, you can use the 'utf-8' encoding, which is a more universal encoding that supports a wider range of characters.

Here's an example of how you can decode a byte string using the 'utf-8' encoding:

byte_string = b'some byte string'
decoded_string = byte_string.decode('utf-8')

You can replace 'utf-8' with any other encoding that supports the characters in the string.
