Step 1. Download PascalVoc segmentation dataset
Step 2. Unpack archive
Step 3. Directory structure have to be the following:
.├── ImageSets│ └── Segmentation│ ├── train.txt│ ├── trainval.txt│ └── val.txt├── JPEGImages│ ├── 2007_000032.jpg│ ├── 2007_000033.jpg│ ├── ...├── SegmentationClass│ ├── 2007_000032.png│ ├── 2007_000033.png│ ├── ...└── SegmentationObject├── 2007_000032.png├── 2007_000033.png├── ...
Step 4. Choose all (four) subdirectories and drag and drop them to browser.
If you will drag and drop parent directory instead of its contents, import will crash.
