Cannot import numpy/openCV #106

Open kandabi opened 2 years ago

kandabi commented 2 years ago

Following the linedraw docs we get the following error in python shell: >>> from linedraw import *
Cannot import numpy/openCV. Switching to NO_CV mode.

Checking pip lists the following packages: numpy: 1.19.4 opencv-python-headless 4.5.5.62 pigpio 1.78 Pillow 8.0.1 pip 20.3.4 readchar 2.0.1 tqdm 4.54.0

Is there any specific opencv-python-headless version required? Thanks.
