Some error in the import statements

[buemi]

Hi,
I failed to run the algorithm due to memory error, I suppose because my system has not enough resources.
Is it possible to "cut" the 22.npz input file reducing its length in order to reduce also the memory occupation?

Anyway I had to modify some line of the code in order to execute it:

• In main.py line 3 rename utils with slam_utils
• In main.py line 4 rename slam_utils with slam
• In slam.py line 3 rename utils with slam_utils

Regards
