I also have a similar problem,when I run rolling train example :

~\AppData\Roaming\Python\Python37\site-packages\qlib\workflow\recorder.py in _log_uncommitted_code(self)
371 try:
372 out = subprocess.check_output(cmd, shell=True)
--> 373 self.client.log_text(self.id, out.decode(), fname) # this behaves same as above
374 except subprocess.CalledProcessError:
375 logger.info(f"Fail to log the uncommitted code of $CWD when run {cmd}")

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xca in position 1233: invalid continuation byte

Can this PR solve your problem?

The meaning of the _log_uncommitted_code method is to save uncommitted changes to your project directory in:
mlruns/<experiment_id>/<recorder_id>/artifacts.
