I am using the opencv-python project here. What I would like to do is recreate the wheel file again. So what I did was something like:
python setup.py bdist_wheel
This creates a dist directory and adds the wheel file there which I then take and try to install in an Anaconda environment as follows:
pip install ~/opencv_python-3.4.2+5b36c37-cp36-cp36m-linux_x86_64.whl
This is fine and seems to install fine. But when I try to use it and do
import cv2
I get the error:
ImportError: libwebp.so.5: cannot open shared object file: No such file or directory
I thought that creating the wheel file would take care of all the dependencies but I wonder if I have to do something else before the wheel generation to make sure everything is packaged correctly?
EDIT
I compare the wheel archives from the official sources and the one I generated and I see that the third party libraries are not included. So, my zip file contents are:
['cv2/LICENSE-3RD-PARTY.txt',
'cv2/LICENSE.txt', 'cv2/__init__.py',
'cv2/cv2.cpython-36m-x86_64-linux-gnu.so']
I have omitted some XML files which are not relevant. Meanwhile, the official archive has:
