Description

Hello.
![image](https://user-images.githubusercontent.com/26546178/64880899-0923f000-d662-11e9-9bb8-03e3a47c2d44.png)

Here we see that map path in train json is incorrect.
Also in kernels i see this code:
```
!ln -s $DATASET_PATH/train_images images
!ln -s $DATASET_PATH/train_maps maps
!ln -s $DATASET_PATH/train_lidar lidar
```
Maybe paths other than train_maps also broken

Research direction

Start by inspecting the train JSON referenced in the report and the kernel commands that link train_images, train_maps, and train_lidar. Check whether the recorded map path and the other training-data paths resolve to the linked directories. Done means the JSON paths and kernel links consistently locate the intended dataset files.
