Disabling keras or tensorflow outputs

I know that there are already some similar questions here on stackoverflow but none of them solved my problem. In a python script, I have to train a keras model multiple times and I want to do this with GPU support. Each time I get a bunch of lines in the output console which is disturbing because I can not see the useful information anymore. Here is a part of the output.

I tried some methods I found on the internet including the following, but nothing worked for me.

import os
os.environ["TF_CPP_MIN_LOG_LEVEL"] = "2"

import logging
logging.getLogger("tensorflow").setLevel(logging.ERROR)
logging.getLogger("tensorflow").addHandler(logging.NullHandler(logging.ERROR))

Every suggestion is welcome.

About my setup:

 - python 3.6.8 
 - keras 2.3.1 
 - tensorflow 2.0.0 
 - cudatoolkit 10.0.130

I use this simple approach, works for me.

# tacke future warning, deprecated warning, bla bla 
import warnings

# ------------ tackle some noisy warning
def warn(*args, **kwargs):
    pass
warnings.warn = warn
warnings.simplefilter(action="ignore", category=FutureWarning)
warnings.filterwarnings("ignore", category = DeprecationWarning)

'''
TF_CPP_MIN_LOG_LEVEL = 0 to all logs .
TF_CPP_MIN_LOG_LEVEL = 1 to filter out INFO logs 
TF_CPP_MIN_LOG_LEVEL = 2 to additionall filter out WARNING 
TF_CPP_MIN_LOG_LEVEL = 3 to additionally filter out ERROR.
'''
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'

# now import tf 
import tensorflow as tf

This tutorial in the Tensorflow Documenation discusses using metadata DB(MLMD) APIs to prevent the printing of outputs. This might apply to your application.
