Executing the edge-connect model in Windows 10

Sicily-F commented 3 years ago

Hi there,

Has anyone run the train.py file in Windows 10?

I keep getting the following traceback:

Traceback (most recent call last):

        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

I tried placing this code at the beginning

if __name__ == "__main__":

    main()

And then indenting everything else below it in the main.py file. However, this also doesn't work, does anyone have any other workarounds they could suggest?

I would be forever grateful!

I hope you have figured it out by now, but for future visitors change train.py from

from main import main
main(mode=1)

to

from main import main
if __name__ == "__main__":
    main(mode=1)

你好，不知这个问题拟解决了吗，我试着按上面那个评论改，结果又出来了其他错误
