Failed to load nodelet.

[nisailhan]

Hi everyone,

When I launch the preprocessing launch file, I get this error as you can see below. My system and package configuration: Operating System & Version Ubuntu 18.04.5 LTS ROS Version: Melodic Kernel Version: 5.11.0-051100-generic Architecture: x86-64 Firmware Version: E16V3IMS.104 PCL Version: 1.8 CMake Version: 3.10.2 Boost Version: 1.65.1.0ubuntu1 OpenCV Version: 3.2.03.3.9 Eigen Version: 3.3.9

Is anyone have an idea?
