python - ROS Noetic (Ubuntu 20.04)

问题描述

Ubuntu 20.04 LTS Python 3.8 ROS Noetic Desktop 完整安装

确认我确实有文件/lib/libgdal.so.26

Performed pip3 install opencv-pythonalready Performed sudo apt install --reinstall gdal-bin libgdal-dev python3-gdalalready Performed sudo apt-get install ros-noetic-cv-bridgealready -- 上述结果是 ros-noetic-cv-bridge 已经是最新版本。

但是，当我的代码上线时

from cv_bridge.boost.cv_bridge_boost import getCvType

我明白了

ImportError: /lib/libgdal.so.26: undefined symbol: sqlite3_column_table_name我不知道如何处理这个

注意：我按照Unable to use cv_bridge with ROS Kinetic and Python3中的说明进行操作

我尝试用“noetic”替换“动力学”并用我的（1.15.0）替换版本号。

按照catkin build cv_bridge指示进行操作，但给了我一些奇怪的输出。

警告 << cv_bridge:make /home/tdadmin/catkin_workspace/logs/cv_bridge/build.make.000.log cc1plus
：警告：/home/tdadmin/.local/bin/python3.6m：不是目录 cc1plus：警告：/ home/tdadmin/.local/bin/python3.6m：不是目录 cc1plus：警告：/home/tdadmin/.local/bin/python3.6m：不是目录 cc1plus：警告：/home/tdadmin/.local/bin /python3.6m: 不是目录 cd /home/tdadmin/catkin_workspace/build/cv_bridge; catkin build --get-env cv_bridge | catkin env -si /usr/bin/make --jobserver-auth=3,4; 光盘 -

我不知道它为什么要看 python3.6m 的任何东西。我按照 3.8 的说明设置了可执行行。

E: 下面是~/catkin_workspace/src/vision_opencv/cv_bridge/CMakeLists.txt 内容。

cmake_minimum_required(VERSION 3.0.2)
project(cv_bridge)

find_package(catkin REQUIRED COMPONENTS rosconsole sensor_msgs)

if(NOT ANDROID)
  find_package(PythonLibs)

  if(PYTHONLIBS_VERSION_STRING VERSION_LESS "3.8")
    # Debian Buster
    find_package(Boost REQUIRED python37)
  else()
    # Ubuntu Focal
    find_package(Boost REQUIRED python)
  endif()
else()
find_package(Boost REQUIRED)
endif()

set(_opencv_version 4)
find_package(OpenCV 4 QUIET)
if(NOT OpenCV_FOUND)
  message(STATUS "Did not find OpenCV 4, trying OpenCV 3")
  set(_opencv_version 3)
endif()

find_package(OpenCV ${_opencv_version4} REQUIRED
  COMPONENTS
    opencv_core
    opencv_imgproc
    opencv_imgcodecs
  CONFIG
)

catkin_package(
  INCLUDE_DIRS include
  LIBRARIES ${PROJECT_NAME}
  CATKIN_DEPENDS rosconsole sensor_msgs
  DEPENDS OpenCV
  CFG_EXTRAS cv_bridge-extras.cmake
)
catkin_python_setup()

include_directories(include ${Boost_INCLUDE_DIRS} ${OpenCV_INCLUDE_DIRS} ${catkin_INCLUDE_DIRS})
link_directories(${Boost_LIBRARY_DIRS})

if(NOT ANDROID)
add_subdirectory(python)
endif()
add_subdirectory(src)
if(CATKIN_ENABLE_TESTING)
  add_subdirectory(test)
endif()

# install the include folder
install(
  DIRECTORY include/${PROJECT_NAME}/
  DESTINATION ${CATKIN_PACKAGE_INCLUDE_DESTINATION}
)

也就是说，这个目录中还有很多其他 CMakeLists.txt，包括

./src/vision_opencv/cv_bridge/python、./src/vision_opencv/cv_bridge/test、./src/vision_opencv/cv_bridge/、./src/vision_opencv/cv_bridge/src

E2：这些是来自的结果catkin build cv_bridge
