TypeError: 'generator' object has no attribute '__getitem__'

Hi,
Here is what I have encountered when I run the code which you provided "Project 3D Velodyne points to 2D camera Image ", I got error message.
I put the code you provided in ipython notebook inside one file called, "projectVelo.py", and I only changed the path to velodyne and image file.

Here is the error message:

Traceback (most recent call last):
File "projectVelo.py", line 60, in
img, pnt, c_ = res.velo_projection_frame(v_fov=v_fov, h_fov=h_fov)

res, c_ = self.__velo_2_img_projection(velo_gen)

File "/home/keisha_tsai/Downloads/KITTI_Tutorial-master/kitti_foundation.py", line 296, in __upload_points
self.__x = points[:, 0]
TypeError: 'generator' object has no attribute 'getitem'

Hope anyone can help me to solve this problem.
Thank you.

The problem didn't occur when I used the code which provided in "velo2cam_projection_detail.ipynb".
Still don't know why, but at least I can get the proper result.
