I spent two whole days to install OpenCV, virtualenv, Tensorflow. My last goal is to link locally installed OpenCV to my virtualenv. I reallized that I do not have to install OpenCV to my virtualenv again, only need to link OpenCV to my virtualenv. I have to find "cv2.so" or "cv2.cpython-37m-aarch64-linux-gnu.so" file. But I can't find any of above file in my Raspberry Pi 4. Anybody can tell me where to find above files or how to link the locally installed OpenCV to virtualenv. I really want to run a python program importing cv2 and tensorflow.

  • In the shell run `sudo find / -name cv2.so` and it will find this file if it is present on the machine. Likewise with the other file. – Nechoj Nov 22 '21 at 16:54
  • find: ‘/tmp/tmp.3YgQjldPvx’: Input/output error find: File system loop detected; ‘/tmp/tmp.rIOenW5uji’ is part of the same file system loop as ‘/’. /etc/dhcpcd.conf find: ‘/run/user/1000/gvfs’: Permission denied -> I come across this error message – Jaeho Nov 24 '21 at 00:56

    In this post https://stackoverflow.com/questions/4210042/how-to-exclude-a-directory-in-find-command you can learn how to exclude directories from the search using `find`. The error message indicates you should exclude the dir `/tmp` from the search. Also the `/run` directory. – Nechoj Nov 24 '21 at 08:37
  • I'll try it. Thanks a lot. – Jaeho Nov 25 '21 at 09:48
