How to hide `wxPython` warnings ?

When executing the following script I get warnings like:
WxPython is not found for the current python version.
Pyo will use a minimal GUI toolkit written with Tkinter (if available).
This toolkit has limited functionnalities and is no more
maintained or updated. If you want to use all of pyo's
GUI features, you should install WxPython, available here:
http://www.wxpython.org/
Neither WxPython nor Tkinter are found for the current python version.

from signal import sigwait, SIGINT
from pyo import *
import os
import contextlib
import warnings
s = Server()
with open(os.devnull, "w") as f, contextlib.redirect_stdout(f):
warnings.filterwarnings('ignore', category=PendingDeprecationWarning)
s.boot()
s.start()
# Sets fundamental frequency.
freq = 187.5
# Roland JP-8000 Supersaw emulator.
lfo4 = Sine(0.1).range(0.1, 0.75)
osc4 = SuperSaw(freq=freq, detune=lfo4, mul=0.3).out()
# Interpolates between input objects to produce a single output
sigwait([SIGINT])
s.stop()
s.shutdown()
I don't want install wxPython
but use pyo
without those warnings. Is that possible to hide the warnings ?

Set PYO_GUI_WX
environment variable to be 0 will hide that warning.
export PYO_GUI_WX=0

Seems not to work:
from pyo import Server, Sine, SuperSaw, time
from PyQt5.QtWidgets import QApplication, QWidget
import threading
import sys
import os
os.environ['PYO_GUI_WX'] = '0'
class Sound:
def __init__(self):
self.server = Server()
self.server.deactivateMidi()
self.server.setBufferSize(512)
def start(self):
self.server.boot().start()
def stop(self):
self.server.stop()
def _synth(self):
# Sets fundamental frequency.
freq = 187.5
# Roland JP-8000 Supersaw emulator.
lfo4 = Sine(0.1).range(0.1, 0.75)
osc4 = SuperSaw(freq=freq, detune=lfo4, mul=0.3).out()
while True:
time.sleep(.0001)
def synth(self):
self.synth_thread = threading.Thread(target=self._synth, daemon=True)
self.synth_thread.start()
class Window(QWidget):

super().__init__()
self.show()
self.sound = Sound()
self.sound.start()
self.sound.synth()

return super().closeEvent(event)

sys.exit(app.exec_())

You need to do it before importing pyo!

Makes sense. Thanks Oliver and Lex!

Yes, it's true... There's nothing to prevent this message from being
printed right now...

Can this be fixed?
