Suppressing Stan optimizer printing in Python

Hi,

I recently started using Prophet in Python, and whilst it is working (quite well), it is printing out messages which appear to be generated by PySTAN and suppressing output from stdout, stderr, and stdin doesn't seem to stop it. Could you add an option to suppress output from PySTAN. I've attached screenshots of the output and the function I am trying to use to suppress the output which is not working:



Kind regards,
