How to suppress console output in Python?

Just for completeness, here's a nice solution from Dave Smith's blog:

from contextlib import contextmanagerimport sys, os@contextmanagerdef suppress_stdout():    with open(os.devnull, "w") as devnull:        old_stdout = sys.stdout        sys.stdout = devnull        try:              yield        finally:            sys.stdout = old_stdout

With this, you can use context management wherever you want to suppress output:

print("Now you see it")with suppress_stdout():    print("Now you don't")

To complete charles's answer, there are two context managers built in to python, redirect_stdout and redirect_stderr which you can use to redirect and or suppress a commands output to a file or StringIO variable.

import contextlibwith contextlib.redirect_stdout(None):    do_thing()

For a more complete explanation read the docs

A quick update: In some cases passing None might raise some reference errors (e.g. keras.models.Model.fit calls sys.stdout.write which will be problematic), in that case pass an io.StringIO() or os.devnull.

You can get around this by assigning the standard out/error (I don't know which one it's going to) to the null device. In Python, the standard out/error files are sys.stdout/sys.stderr, and the null device is os.devnull, so you do

sys.stdout = open(os.devnull, "w")sys.stderr = open(os.devnull, "w")

This should disable these error messages completely. Unfortunately, this will also disable all console output. To get around this, disable output right before calling the get_hat() the method, and then restore it by doing

sys.stdout = sys.__stdout__sys.stderr = sys.__stderr__

which restores standard out and error to their original value.
