There is a "RuntimeError" when I use this command to run the program, my environment is windows10 64bit system.

python test.py --dataroot E:\test_opencv\DeblurGAN-master(fangzhishoudou)\pictest\ --model test --dataset_mode single --learn_residual

There is a "RuntimeError" when I use the above command to run the program,how can I fix this error? Error message is following.

    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.

Hello, unfortunately I am not able to test it on Windows but it seems that you have troubles with multiprocessing, try this - https://medium.com/@mackie__m/running-a-cifar-10-image-classifier-on-windows-with-pytorch-9094e29089cd

To fix this issue the code after the imports in test.py must be the body of this if:

if __name__ == '__main__':
    <original code in test.py>
