Evaluate kitti--AttributeError: 'NoneType' object has no attribute 'shape'

[chmod770-before-agreeing]

When I try to evaluate the kitti dataset as is said in the GETTING_STARTED.MD , some problems occured during the running step just like :

I will be grateful for your help

It says the images are not loaded. Can you check you have placed the dataset correctly?

Maybe the path contain the non-ascii words.

I had the same problem. For some reason the simlinks that are created during the data preparation process described in DATA.md are not working. So instead of creating simlinks I simply copied the actual data into the directories indicated in DATA.md. In other words the folders data/kitti/images/test and data/kitti/images/trainval do contain the actual images.

my data path like this

height, width = image.shape[0:2] add try Except: ok because the image is not exist

[chaoswjc]

try ln -s ../training/image_2 images/trainval instead of ln -s training/image_2 images/trainval

[yanzhao16]

try ln -s ../training/image_2 images/trainval instead of ln -s training/image_2 images/trainval

This answer is correct.
