opencv - import cv2 在使用 python 3.6 的 jupyter notebook 中返回错误

Question

我需要下载 opencv 来运行需要 python 3.6 和 opencv 的项目。我已经下载了opencv。

我知道我的错误类似于OpenCV 在使用 import cv2 时给出错误，但我已经尝试了该问题中提到的两种解决方案，但都不适合我。

!pip install opencv-python

Requirement already satisfied: opencv-python in /Users/aa/.conda/envs/py36/lib/python3.6/site-packages (3.4.2.16)
Requirement already satisfied: numpy>=1.11.3 in /Users/aa/.conda/envs/py36/lib/python3.6/site-packages (from opencv-python) (1.18.3)

但是当我输入

import cv2

我收到以下错误：

ImportError                               Traceback (most recent call last)

  2

  4 from .data import *
  5 

 ImportError: dlopen(/Users/aa/.conda/envs/py36/lib/python3.6/site-packages/cv2/cv2.cpython-36m-darwin.so, 2): Symbol not found: __ZN10QBoxLayout10invalidateEv

我也尝试使用 conda 安装，但总是出现以下错误：
