今天，我尝试运行autokeras，但失败，错误消息如下所示：
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.
昨天，我运行了演示，它运行良好。我徘徊为什么会这样？
任何帮助！首先谢谢。
