import cv2 导致 Segmentation fault (core dumped)

Question

在运行文件的时候出现Segmentation fault (core dumped)的错误
经过排查，在即使只有一句 import cv2的文件中运行也会产生这个错误
怀疑是因为opencv的原因
我的opencv的安装是参照https://pyimagesearch.com/2018/09/19/pip-install-opencv/
查找解决方法时，有人提议使用_LD_DEBUG=files python -c "import cv2"_来查看错误
但是我看不懂以下的输出。请问有无办法解决这个问题？

问题已解决，我重装了opencv-contrib-python包，就没问题了
