Suppress warnings with loading tiff images in tensorflow doesn't seem to work?

Question

I keep getting the following warning when using tfio.experimental.image.decode_tiff. I find that it works fine but keeps giving these warnings, which I want to suppress.

TIFFFetchNormalTag: Warning, ASCII value for tag "DateTime" contains null byte in value; value incorrectly truncated during reading due to implementation limitations.

I am using it as follows:

string = tf.io.read_file(filename)
image = tfio.experimental.image.decode_tiff(string) # this line produces warning

If I try to suppress the warning using warning, it doesn't seem to work? It doesn't give me an error, but it doesn't do anything.

import warnings
warnings.filterwarnings('ignore', message='ASCII value for tag "DateTime" contains null byte in value; value incorrectly truncated during reading due to implementation limitations')

How can I suppress this warning, or alternatively address the issue that produces the warning?

Answer 1

If you want to supress all warning then you can use

  warnings.filterwarnings("ignore")

If want to supress some mesage then you have to use message=... with beginning of message or with .* at the beginning

  warnings.filterwarnings("ignore", message=".*ASCII value for tag")

---

Minimal example:

import warnings

warnings.filterwarnings("ignore", message=".*ASCII value for tag")

# some tests - it should be supressed by `filterwarnings()`
warnings.warn('TIFFFetchNormalTag: Warning, ASCII value for tag "DateTime" contains null byte in value; value incorrectly truncated during reading due to implementation limitations.')

print("Hello World")
