He estado tratando de configurar el uso de Chrome DevTools el uso de Selenio 4 y Python. He sido capaz de conseguir que se ejecute localmente (sin que ninguno de los async cosas), pero cuando trato de usar el webdriver.Implantación remota, se bloquea.
Aquí es un ejemplo de que el Selenio docs: https://www.selenium.dev/de/documentation/support_packages/chrome_devtools/
A continuación es cómo he probado a ejecutarlo.
import asyncio
from selenium import webdriver
import selenium.webdriver.common.devtools.v96 as devtools
async def geo_location_test():
try:
chrome_options = webdriver.ChromeOptions()
driver = webdriver.Remote(
command_executor='http://D5365900:4444/wd/hub',
options=chrome_options
)
async with driver.bidi_connection() as session:
cdp_session = session.session
await cdp_session.execute(devtools.emulation.set_geolocation_override(latitude=41.8781,
longitude=-87.6298,
accuracy=100))
driver.get("https://my-location.org/")
finally:
driver.quit()
async def main():
await geo_location_test()
if __name__ == "__main__":
asyncio.run(main())
Corre hasta la línea de async with driver.bidi_connection() as session: (se establece la sesión y el navegador Chrome se abre). Pero el que se bloquea con la siguiente traza.

Como puede ver, estoy usando Python 3.10. También he actualizado el Selenio enlaces a la 4.1.0 y estoy ejecutando un Selenio 4.0.0 Hub/Nodo de configuración para automatizar Chrome 96.
Cualquier idea, ¿cuál es el problema aquí? Soy el manejo de la asincrónico corrutinas incorrectamente?
Cualquier ayuda se agradece mucho!
Actualización Después de intentar ejecutar con trio (como se sugiere en Henry Ashton-Martyn del comentario), me sale el siguiente error.
Traceback (most recent call last):
File "C:\Program Files\Python310\lib\site-packages\trio\_highlevel_open_tcp_stream.py", line 332, in attempt_connect

The above exception was the direct cause of the following exception:
