I built the Dockerfile and tried to execute
python -c "import cv2; print(cv2.__version__)"
.Though I got error.
Finally, I found a symbolic link was missing, and Added it.
Actually, I do not know if hard cording
cv2.cpython-37m-x86_64-linux-gnu.so
is allowed, though this modification fixed my issue.Thank you.
