run_dataset报错求助

[zhongyouque]

我在进行测试run_dataset的时候出现了如下错误：

    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.

可以通过以下解决：
if name == 'main':
run_dataset(
config = "aligned",
dataset_dir="./MOSI",
out_file="./feature.pkl",
num_workers=1
)
