Cannot remove WARNING: messages from output

Hi,

I'm trying to list all the codebar data from large files, and I want a clean output. However, I keep getting WARNING: messages and I can't find a way to get rid of them. I saw this similar issue (29) but the resolution didn't work for me.

The warning messages I get (which I don't really understand to be honest) :

It seems that it's trying to read PDF417 eventhough I specified to read CODE128

WARNING: .\zbar\decoder\pdf417.c:89: <unknown>: Assertion "g[0] >= 0 && g[1] >= 0 && g[2] >= 0" failed.
    dir=1 sig=9d9b k=0 g0=217 g1=47d g2=ffffffff buf[0000]=

I have no clue about this error

WARNING: zbar\decoder\databar.c:1250: <unknown>: Assertion "seg->finder >= 0" failed.
    i=10 f=-1(000) part=1

The fixes I tried :

Removing warnings and redirecting stderr to null

import os
import sys
import warnings

warnings.filterwarnings('ignore')

f = open(os.devnull, 'w')
sys.stderr = f

Specifying the type of the barcode I'm trying to read

decoded_objects = decode(Image.open(tiff), symbols=[ZBarSymbol.CODE128])

None of them worked. Is there any way to have a clean output ? I'm running out of solutions..
