Key 'collate_landmarks' was used the wrong number of times

[nkuligaofeng]

I'm learning the cartographer these days. I have successfully run the 2D backpack demo and the 3D backpack demo. However, I face a problem when I run the Static Landmarks demo.
Here is the problem.
I have install the "cartographer_mir" successfully. When I try to launch the landmarks demo as guided by https://google-cartographer-ros.readthedocs.io/en/latest/demos.html:
roslaunch cartographer_mir offline_mir_100_rviz.launch bag_filename:=${HOME}/Downloads/landmarks_demo_uncalibrated.bag
, I meet the following error:

[...../offline_mir_100_rviz.launch] requires the 'bag_filenames' arg to be set

So I checked the "offline_mir_100_rviz.launch" file and found that the arg name is 'bag_filenames' instead of ‘bag_filename’. So a 's' is missing in the commend line shown in https://google-cartographer-ros.readthedocs.io/en/latest/demos.html.

However, I meet another error when I fix this problem:

[FATAL] [1542782924.721540472]: F1121 14:48:44.000000 27311 lua_parameter_dictionary.cc:410] Check failed: 1 == reference_counts_.count(key) (1 vs. 0) Key 'collate_landmarks' was used the wrong number of times.

I checked the configurations file: /cartographer_mir/cartographer_mir/configuration_files/mir-100-mapping.lua. I found that the parameter "collate_landmarks" is set to be false. So I modify it to be true as following:
TRAJECTORY_BUILDER.collate_landmarks = true

However, the error is same:

[FATAL] [1542782924.721540472]: F1121 14:48:44.000000 27311 lua_parameter_dictionary.cc:410] Check failed: 1 == reference_counts_.count(key) (1 vs. 0) Key 'collate_landmarks' was used the wrong number of times.

Could someone to help me? I don't know what's the problem.

I have solved this problem.
Actually, the value of the parameter "collate_landmarks" should not be "true" or "false". It should be "on" or "off".
Also, the value for "use_pose_extrapolator" should be "on".

So when I modify the .lua file as following, I run the Static Landmarks demo successfully.

use_pose_extrapolator = on
TRAJECTORY_BUILDER.collate_landmarks = on

This doesn't work, I still has the same problem:

Update

I have solved the problem, after change the configure file, you should rebuild the cartographer_mir, or you can change the configure file in /install_isolated/share/cartographer_mir/configuration_files/mir-100-mapping.lua
