KeyError: 'Tr'

[arkin8858]

Hello,
Bundle of thanks sharing such an amazing code . i have created required environment after few modification according to the nvidia gpu. However stuck at this following error;

data['T_cam0_velo'] = np.reshape(filedata['Tr'], (3, 4))
KeyError: 'Tr'

I rechecked my calib.txt and Tr matrix is provided in that file however during evaluation of kitti odometry dataset sequence 00 as given default params, i've got Tr keyerror. i tried to check the pykitti and installed from the source as well but still same issue.

Could anyone guide me regarding this issue. @howtocodewang @LvXudong-HIT @Sibozhu

Thanks

@arkin8858 Have you solved this problem?

Download data_odometry_calib.zip file and unzip it on the dataset path

Actually, you need to download the lidar dataset, in which you will find Tr data inside.

解压缩四个压缩包，之后手动把sequences的内容放到一起
