MaixPy Source Code FAQ

subprocess.CalledProcessError: Command '('lsb_release', '-a')' returned non-zero exit status 1.

Edit /usr/bin/lsb_release as root, change the first line from #!/usr/bin/python3 to python3.

Then compile again and it should work.

ImportError: arg(): could not convert default argument 'format: maix::image::Format' in method '<class ''>.init' into a Python object (type not registered yet?)

Pybind11 need you to register image::Format first, then you can use it in camera::Camera, to we must fist define image::Format in generated build/maixpy_wrapper.cpp source file.

To achieve this, edit components/maix/headers_priority.txt, the depended on should be placed before the one use it.


/usr/bin/ld: /lib/ undefined reference to `std::condition_variable::wait(std::unique_lockstd::mutex&)@GLIBCXX_3.4.30' collect2: error: ld returned 1 exit status

This issue commonly arises when building for Linux and using a conda environment, due to some libraries in the conda environment having compilation parameter problems. The solution is to not use conda, or to individually locate the problematic library within conda and replace it with the system's version or simply delete it (the system will then locate the necessary library).
