if name == ‘main’:
freeze_support() 还是不行，以下是报错信息

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.
