Error 1: sudo pip install python-igraph –upgrade failed

Solution:

sudo apt-get install python-igraph

Error 2:

Could not find a package configuration file provided by “code_utils” with
any of the following names:
code_utilsConfig.cmake
code_utils-config.cmake```

Solution:

1. You need to put the following sentence in the sumpixel_test.cpp file
   #include “backward.hpp”
   to this line
   #include “code_utils/backward.hpp”
2. Put code_utils into the workspace first, then catkin_ws once, then put imu_utils, then compile

 

Error 3: catkin build -DCMAKE_BUILD_TYPE=Release -j4 errors during compilation
