RuntimeError:
An attempt has been made to start a new process before the
current process has finished its bootstrapping phase.
This probably means that you are not using fork to start your
child processes and you have forgotten to use the proper idiom
in the main module:
if name == ‘main’:
freeze_support()
…
The “freeze_support()” line can be omitted if the program
is not going to be frozen to produce an executable.

同样出现这个问题。我看这个问题出现的还不少，老师可以统一做个说明

• 兰陵小生 #1

  github 上面已经取消undetected_chromedriver.v2的引用，请直接使用import undetected_chromedriver as uc
