Does Ray has an option to disable buffer when print out the trial status? This would be helpful when redirecting stdout to a file and view the output in real time. For python script, one can use “python -u " do it but in ipython there’s no such option. Would be nice to have an option in ray to enable print(…, flush=True”)
found the solution: just set the environment variable PYTHONUNBUFFERED to anything other than 0
