如何将python3链接到特定版本的opencv？
如何将python3链接到特定版本的opencv？
提问于 2021-04-07 21:41:17
我成功编译并安装了OpenCV 4.5.0，但是当我使用python3导入cv2时，我发现cv2的版本是4.5.1。类似于以下输出：
Python 3.6.9 (default, Oct 8 2020, 12:12:24)
[GCC 8.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> print(cv2.getBuildInformation())
General configuration for OpenCV 4.5.1 =====================================
Version control: 4.5.1-dirty
Platform:
Timestamp: 2021-01-02T12:47:39Z
Host: Linux 5.4.0-54-generic aarch64
CMake: 3.18.4
CMake generator: Unix Makefiles
CMake build tool: /bin/gmake
Configuration: Release
.........
Python 3:
Interpreter: /opt/python/cp36-cp36m/bin/python (ver 3.6.12)
Libraries: libpython3.6m.a (ver 3.6.12)
numpy: /tmp/pip-build-env-c03ewnak/overlay/lib/python3.6/site-packages/numpy/core/include (ver 1.19.3)
install path: python
Python (for build): /bin/python2.7
Install to: /tmp/pip-req-build-zuuo394f/_skbuild/linux-aarch64-3.6/cmake-install
-----------------------------------------------------------------当我打开/tmp时，我找不到文件夹/pip-req-build-zuuo394f。
但是当我使用python(2.7.17)时，我得到了正确的opencv版本：
Python 2.7.17 (default, Sep 30 2020, 13:38:04)
[GCC 7.5.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> print(cv2.getBuildInformation())
General configuration for OpenCV 4.5.0 =====================================

numpy: /usr/lib/python2.7/dist-packages/numpy/core/include (ver 1.13.3)
install path: lib/python2.7/dist-packages/cv2/python-2.7
Python 3:

numpy: /usr/lib/python3/dist-packages/numpy/core/include (ver 1.13.3)
install path: lib/python3.6/dist-packages/cv2/python-3.6
Python (for build): /usr/bin/python2.7
Install to: /usr
-----------------------------------------------------------------在Python2的cv2中，cv2中的所有函数都可以正常工作。那么，如何在python3中更改cv2版本呢？非常感谢!

我遵循@Peter的建议print(cv2)。我在/home/.local/lib/python3.6/site-packages/cv2文件夹中找到了一个cv2.so，但我的OpenCV 4.5.0安装在usr/lib/python3.6/dist-packages/cv2中。
然后，我删除了/home/...中的cv2文件夹，并再次使用import cv2，cv2.__version__现在是4.5.0版本，所有功能都正常工作。
