gluonCV:voc is not a valid dir. Did you forget to initalize

https://gluon-cv.mxnet.io/build/examples_segmentation/index.html

使用gluoncv做Semantic Segmentation,运行demo_fcn.py报错

OSError: /home/xxx/.mxnet/datasets/voc is not a valid dir. Did you forget to initalize datasets described in: http://gluon-cv.mxnet.io/build/examples_datasets/index.html? You need to initialize each dataset only once.

有人知道为什么吗

你需要手动创建相应的目录。
