How to turn off skimage warnings

Question

I want to turn off skimage UserWarning: I used this code but they are still enabled.

with warnings.catch_warnings():
    warnings.simplefilter("ignore")
    skimage.io.imsave

May be because skimage uses their own warning library... (?) https://github.com/scikit-image/scikit-image/blob/master/skimage/io/_io.py — Eskapp, Sep 26 '18 at 19:33

I found in the documentation that there is a dedicated option "check_contrast" when imsave is called: https://scikit-image.org/docs/dev/api/skimage.io.html?#imsave

If you want to disable imsave warnings indicating a low contrast image you should set this option to False: check_contrast=False

from skimage import io

io.imsave(filename, image, check_contrast=False)

Apparently skimage uses imageio as his first plugin option to save an image.

Try to:

import imageio.core.util

def ignore_warnings(*args, **kwargs):
    pass

imageio.core.util._precision_warn = ignore_warnings

After that, you can save your image without the warnings:

imsave(filename, image)
