Failed to build tensorflow_ros_cpp #112

Closed mengyuest closed 5 years ago

mengyuest commented 5 years ago

I am stuck in the Build tensorflow_ros_cpp section failing to compile the tensorflow_ros_cpp. I use Ubuntu16.04 and have successfully compiled tensorflow1.8 from source. The error message shows

Errors     << tensorflow_ros_cpp:cmake /home/meng/segmap_ws/logs/tensorflow_ros_cpp/build.cmake.001.log
CMake Error at /home/meng/segmap_ws/src/tensorflow_ros_cpp/CMakeLists.txt:4 (find_package):
  By not providing "Findcatkin.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "catkin", but
  CMake did not find one.

  Could not find a package configuration file provided by "catkin" with any
  of the following names:

    catkinConfig.cmake
    catkin-config.cmake

  Add the installation prefix of "catkin" to CMAKE_PREFIX_PATH or set
  "catkin_DIR" to a directory containing one of the above files.  If "catkin"
  provides a separate development package or SDK, be sure it has been
  installed.

cd /home/meng/segmap_ws/build/tensorflow_ros_cpp; catkin build --get-env tensorflow_ros_cpp | catkin env -si  /usr/bin/cmake /home/meng/segmap_ws/src/tensorflow_ros_cpp --no-warn-unused-cli -DCATKIN_DEVEL_PREFIX=/home/meng/segmap_ws/devel -DCMAKE_INSTALL_PREFIX=/home/meng/segmap_ws/install -DCMAKE_BUILD_TYPE=Release; cd -

Is there any extra step shall I do before compiling tensorflow_ros_cpp? Thanks for your help~

Also I am using virtual env for python3.5 and the result from pip list is

Do you have ros installed? And if so it seems the ros environment might not be source, e.g. source /opt/ros/<ROS-DISTRO>/setup.bash where you need to replace <ROS-DISTRO> with the version of ros you are running.

mengyuest commented 5 years ago

Thanks for your in-time response. I sourced my ros-kinetic and catkin make again, but it showed the following error. I am not sure how to let the package find the tensorflow. In the virtual environment I can import tensorflow in python3, and I also tried to set FORCE_TF_PIP_SEARCH=True but it still failed. Do you have any suggestions on how to declare the library path or something? Thanks again.

As you have Ubuntu 16 you need to custom compile tensorflow for ABI compatibility. See here and here for examples on the flags for different ways of compiling tensorflow_ros_cpp by either linking against pip or bazel respectively.

Thanks! Following the instructions in FAQ now I can build tensorflow_ros_cpp successfully.
