MindSpore C++ Library Use

Q：What should I do when error /usr/bin/ld: warning: libxxx.so, needed by libmindspore.so, not found prompts during application compiling?

A：Find the directory where the missing dynamic library file is located, add the path to the environment variable LD_LIBRARY_PATH, and refer to Inference Using the MindIR Model on Ascend 310 AI Processors#Building Inference Code for environment variable settings.

Q：What should I do when error undefined reference to mindspore::GlobalContext::SetGlobalDeviceTarget(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char>> const &) prompts during application compiling?

A：Since MindSpore uses the old C++ ABI, applications must be the same with MindSpore and add compile definition -D_GLIBCXX_USE_CXX11_ABI=0, otherwise the compiling will fail. Refer to Inference Using the MindIR Model on Ascend 310 AI Processors#Introduce to Building Script for cmake script.

Q：What should I do when error ModuleNotFoundError: No module named 'te' prompts during application running?

A：First confirm whether the system environment is installed correctly and whether the whl packages such as te and topi are installed correctly. If there are multiple Python versions in the user environment, such as Conda virtual environment, you need to execute ldd name_of_your_executable_app to confirm whether the application link libpython3.7m.so.1.0 is consistent with the current Python directory, if not, you need to adjust the order of the environment variable LD_LIBRARY_PATH.

Q：What should I do when error error while loading shared libraries: libge_compiler.so: cannot open shared object file: No such file or directory prompts during application running?

A：While installing Ascend 310 AI Processor software packages，the CANN package should install the full-featured toolkit version instead of the nnrt version.
