evo can't plot topics of Rosbag

[zhaohaowu]

When I runevo_traj bag ROS_example.bag --all_topics -p there is an error, as follows:

[ERROR] Unhandled error in evo.main_traj
Traceback (most recent call last):

But runningevo_traj kitti KITTI_00_ORB.txt KITTI_00_SPTAM.txt --ref=KITTI_00_gt.txt -p is ok

You have rosbag for ROS melodic (Python 2) but you installed evo for Python 3, this won't work.

So how to solve this problem？

So how to solve this problem？

Downgrade to Python 2 version of the package or upgrade your ROS distribution.
