[fimpen1312]

Hey im a total beginner at python and programming but im getting this error message when running ticker_counts:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

The whole log looks like this:

python3 ticker_counts.py
Traceback (most recent call last):

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

Any help on solving this issue would be much appriciated!
