Run the Example
work4it opened this issue · comments
Hello,
I wanted to try the example. But when I enter the line
wget http://kitti.is.tue.mpg.de/kitti/raw_data/2011_09_26_drive_0002/2011_09_26_drive_0002_sync.zip
I get the following error:
--2018-09-06 16:29:10-- http://kitti.is.tue.mpg.de/kitti/raw_data/2011_09_26_drive_0002/2011_09_26_drive_0002_sync.zip Auflösen des Hostnamen »kitti.is.tue.mpg.de (kitti.is.tue.mpg.de)«... fehlgeschlagen: Der Name oder der Dienst ist nicht bekannt. wget: kann die Host-Adresse »kitti.is.tue.mpg.de« nicht auflösen
I think the website is not available. Is there another way to get the sample data?
Hi, I can confirm that neither can I download the file. Looks like authors of the KITTI dataset moved the files to the S3. The new address is https://s3.eu-central-1.amazonaws.com/avg-kitti/raw_data/2011_09_26_drive_0002/2011_09_26_drive_0002_sync.zip
I got this from the official KITTI website.
Thank you for the fast answer. I was able to download and extract the data from the page. However, if I enter the command, this message comes:
~$ kitti2bag -t 2011_09_26 -r 0002 raw_synced .
Traceback (most recent call last):
File "/usr/local/bin/kitti2bag", line 12, in

ImportError: dynamic module does not define module export function (PyInit__tf2)
Is there any mistake?
Ok in #15 there is the solution:
sudo pip2 install kitti2bag
Why i need this command?
Because ROS only supports (at least officially) python 2. This is not a requirement of the kitti2bag. It works with python 3 too but the ROS-related dependencies are only installed for the python 2. Hope this will change in the future.
