ImportError: libIlmImf-2_2.so.23: cannot open shared object file: No such file or directory

Hello,

I am using python3.7 Raspberry Pi 3 B+ and I an trying install opencv to start a project that is a Self-Driving Robotic Car by Use of Computer Vision. The only library I am having trouble with is OpenCV. I first attempt sudo apt-get install python3-opencv. It worked. However, I need it for python3.7. It installs to python 3.9. I then remove it and try pip3.7 install opencv-python. That didn't work. For some reason the version 4.5.5.62 is not installing. So, I was specific by typing pip3.7 install opencv-python==4.5.3.56 because I read it is compatible with python 3.7. This version installs; however, I recieved the following message:

(driving_cv) pi@raspberrypi:~ $ python3
Python 3.7.4 (default, Jan 29 2022, 23:25:05) 
[GCC 10.2.1 20210110] on linux

>>> import cv2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

    from .cv2 import *
ImportError: libIlmImf-2_2.so.23: cannot open shared object file: No such file or directory
>>> 

I did some research and read I should try the follow command. sudo apt install libopenexr23. However, when executing, it says to replace with libopenexr25 which I do. I recheck python3.7 -c "import cv2" again and get the same error.

Can someoneassist with this issue, please?
