PyTorch error: The "freeze_support()" line can be omitted if the program is not going to be frozen to produce an executable.

The error code is as follows:

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. RuntimeError:

solution

Just put the code block you want to run into the main function and run it, for example:

Login is visible.

distinguish

Code in modules (including function calls) without if __name__ == '__main__':: is also executed when imported.
Add if __name__ == '__main__':: Code in a module (including function calls) is executed only when the module is run as the main program, and not when imported.

This pattern helps improve code reusability and modularity, avoiding accidental execution of certain code when importing modules.
