How to deal with code when use CPU?

[Sakura-Shino]

I try to run the code in virtual machine with only CPU. I have read #6, so i used the code in ego-planner.

Here is what i do:

0. ENV

Ubuntu 20.04
ROS Noetic

1. I copy these files from ego-planner to Elastic-Tracker

src\uav_simulator\local_sensing\src\pcl_render_node.cpp
src\uav_simulator\local_sensing\src\pointcloud_render_node.cpp

2. I set ENABLE_CUDA as false

set(ENABLE_CUDA false)

3. Follow the steps in README 1. Simulation of Aerial Tracking

Issues:

when i triger the drone, i got warning in picture. And the drone0 won't track the target.

here is the topic list:

I really appreciate it if you offer some suggestions.
