Rasp 3 B+, Raspbian
I installed OpenCV using
pip3 install opencv-python
Then tried to
import cv2 which threw the error..
ImportError: libcblas.so.3: cannot open shared object file: No such file or directory
After much searching I found this blog post about missing dependencies & found that the following dependencies are missing,
libcblas.so.3 libatlas.so.3 libjasper.so.3
At this stage in the blog post it suggests using
apt-file to find which packages need installing to get the missing
so's but when I try to install
sudo apt install apt-file I get the following error...
E: Unable to locate package apt-file
I get the same error if I try to install
libjasper which contain the missing
(side note: I am assuming
libcblas is an implimentation of the Basic Linear Algebra Subprograms library?)
So how do I get access to these missing packages & libraries? This is my first exposure to the world of Linux repositories by the way.
