Hi @Maclory thank you for sharing your great work with us when i try to run the code in windows 10 with cpu only ( no gpu ) it give me this error

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.

During handling of the above exception, another exception occurred:

how can i fix this please

Hi, thank you for your interest in our work. We implemented our experiments with GPUs on Ubuntu 16.04 and we never encountered such problems. I guess it may be caused by the environment gap between Ubuntu and Windows.
