- Mapillary Vistas Dataset use 8-bit with color-palette to store labels. No conversion operation is required.

- Assumption you have put the dataset zip file in `mmsegmentation/data/mapillary`

- Please run the following commands to unzip dataset.

  ```bash
  cd data/mapillary
  unzip An-ZjB1Zm61yAZG0ozTymz8I8NqI4x0MrYrh26dq7kPgfu8vf9ImrdaOAVOFYbJ2pNAgUnVGBmbue9lTgdBOb5BbKXIpFs0fpYWqACbrQDChAA2fdX0zS9PcHu7fY8c-FOvyBVxPNYNFQuM.zip
  ```

- After unzip, you will get Mapillary Vistas Dataset like this structure. Semantic segmentation mask labels in `labels` folder.
