문서개요
Jetson Nano (jetpack version 4.6.1) 에서 mediapipe를 설치하고, USB 카메라를 사용하여 Hand Tracking 예제를 실행하는 과정을 서술합니다.
절차
tensorflow (GPU사용) 설치
mediapipe를 이용하기 위해서는 tensorflow가 설치되어야 합니다.
apt update
$ sudo apt update
종속 패키지 설치
$ sudo apt-get install libhdf5-serial-dev hdf5-tools libhdf5-dev zlib1g-dev zip libjpeg8-dev liblapack-dev libblas-dev gfortran $ sudo apt-get install python3-pip $ sudo pip3 install -U pip testresources setuptools $ sudo ln -s /usr/include/locale.h /usr/include/xlocale.h $ pip3 install Cython==0.29.36 $ pip3 install pkgconfig $ git clone https://github.com/h5py/h5py.git $ cd h5py $ H5PY_SETUP_REQUIRES=0 pip3 install . --no-deps --no-build-isolation $ sudo pip3 install -U numpy==1.19.4 future mock keras_preprocessing keras_applications gast==0.2.1 protobuf pybind11 packaging $ sudo pip3 install --extra-index-url https://developer.download.nvidia.com/compute/redist/jp/v461 tensorflow
tensorflow gpu 사용 확인
$ python3 >>> tf.test.is_gpu_available() Use ‘tf.config.list_physical_devices(‘GPU’)’ instead. 또는 $ python3 >>> tf.test.is_gpu_availble() True
위 결과처럼 나올 경우 GPU 사용
opencv 설치
swap 공간 할당
opencv 전체 빌드에는 약 8GB 이상의 램이 필요하며, Jetson nano는 ram이 4GB 이기 때문에 swap 공간을 할당해주어야 합니다.
# 현재경로 : ~/ $ git clone https://github.com/JetsonHacksNano/installSwapfile.git $ cd installSwapfile $ ./installSwapfile.sh
opencv 삭제
$ sudo apt-get install python3-opencv $ sudo apt-get remove python3-opencv $ sudo apt purge libopencv-dev libopencv-python libopencv-samples libopencv*
opencv가 남아있는지 확인
$ pkg-config --modversion opencv4
패키지 업데이트 및 필요한 패키지 설치
$ sudo apt update
$ sudo apt install -y python3-pip python-dev python3-dev python-numpy python3-numpy $ sudo sh -c "echo '/usr/local/cuda/lib64' >> /etc/ld.so.conf.d/nvidia-tegra.conf" $ sudo apt install -y qt5-default $ sudo apt install -y build-essential cmake git unzip pkg-config libswscale-dev $ sudo apt install -y libcanberra-gtk* libgtk2.0-dev $ sudo apt install -y libtbb2 libtbb-dev libavresample-dev libvorbis-dev libxine2-dev $ sudo apt install -y curl
사진, 비디오 포맷 설치
$ sudo apt install -y libxvidcore-dev libx264-dev libgtk-3-dev $ sudo apt install -y libjpeg-dev libpng-dev libtiff-dev $ sudo apt install -y libmp3lame-dev libtheora-dev libfaac-dev libopencore-amrnb-dev $ sudo apt install -y libopencore-amrwb-dev libopenblas-dev libatlas-base-dev $ sudo apt install -y libblas-dev liblapack-dev libeigen3-dev libgflags-dev $ sudo apt install -y protobuf-compiler libprotobuf-dev libgoogle-glog-dev $ sudo apt install -y libavcodec-dev libavformat-dev gfortran libhdf5-dev $ sudo apt install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev $ sudo apt install -y libv4l-dev v4l-utils qv4l2 v4l2ucp libdc1394-22-dev
