ImportError: libcblas.so.3: cannot open shared object file: No such file or directory

Question

I am trying to run an Arducam MT9J001 camera on a raspberry pi 3b+. I am getting the following error when I try to run the program, \"ImportError: libcblas.so3: cannot open

Answer 1

What worked for me (I was missing some dependencies):

pip3 install opencv-python 
sudo apt-get install libcblas-dev
sudo apt-get install libhdf5-dev
sudo apt-get install libhdf5-serial-dev
sudo apt-get install libatlas-base-dev
sudo apt-get install libjasper-dev 
sudo apt-get install libqtgui4 
sudo apt-get install libqt4-test

Answer 2

You need to install only one package with neccessary shared object for it to work

sudo apt-get install libatlas-base-dev

Answer 3

Exact same solution as @thvs86 but here's a single 1 line copy-paste so you don't have to insert each command individually:

pip3 install opencv-contrib-python; sudo apt-get install -y libatlas-base-dev libhdf5-dev libhdf5-serial-dev libatlas-base-dev libjasper-dev libqtgui4 libqt4-test
