- 使用pip 安裝
$ pip install opencv-python
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement opencv-python (from versions: none)
ERROR: No matching distribution found for opencv-python
安裝失敗提示到不到。
上 https://pypi.org/ 查找，得到的是結果這個是非官方的源，是愛好者個人維護，所以pip 沒有自動下載源碼，因爲上面沒提供源碼。源碼在作者的github 裏面。操作如下圖：
2. 下載源碼
$ git clone --depth 1 https://github.com/skvark/opencv-python.git
- 修改源gitee以加快代碼下載速度
$ cat .gitmodules
[submodule "opencv"]
path = opencv
url = https://gitee.com/mirrors/opencv.git
[submodule "opencv_contrib"]
path = opencv_contrib
url = https://gitee.com/mirrors/opencv_contrib.git
[submodule "multibuild"]
path = multibuild
url = https://gitee.com/useptonly/multibuild.git
- 安裝編譯依賴
$ sudo apt install qt4-dev-tools qt4-qmake
$ sudo apt install cmake
$ sudo apt install python3-numpy
$ pip install scikit-build
-
編譯
$ python3 setup.py bdist_wheel -
編譯好的文件：
./dist/opencv_python-4.3.0+3073e9e-cp37-cp37m-linux_mips64.whl -
