error UnicodeDecodeError: 'utf-8' codec ca

Question

https://github.com/affinelayer/pix2pix-tensorflow/tree/master/tools

An error occurred when compiling "process.py" on the above site.

 python tools/process.py --input_dir data --            operation resize --outp
ut_dir data2/resize
data/0.jpg -> data2/resize/0.png

Traceback (most recent call last):

File "tools/process.py", line 235, in <module>
  main()
File "tools/process.py", line 167, in main
  src = load(src_path)
File "tools/process.py", line 113, in load
  contents = open(path).read()
      File"/home/user/anaconda3/envs/tensorflow_2/lib/python3.5/codecs.py", line 321, in decode
  (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode     byte 0xff in position 0: invalid start byte

What is the cause of the error? Python's version is 3.5.2.

Answer 1

Check the path of the file to be read. My code kept on giving me errors until I changed the path name to present working directory. The error was:

newchars, decodedbytes = self.decode(data, self.errors)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

Answer 2

I've come across this thread when suffering the same error, after doing some research I can confirm, this is an error that happens when you try to decode a UTF-16 file with UTF-8.

With UTF-16 the first characther (2 bytes in UTF-16) is a Byte Order Mark (BOM), which is used as a decoding hint and doesn't appear as a character in the decoded string. This means the first byte will be either FE or FF and the second, the other.
