Confirmed. Jetson (nx) with OOB image, then completing the instructions from getting started results in seg fault. so for the timebeing, “modern” Jetpacks are not usable. just downloaded latest 4.5 just released will try again

I will reconfirm again tomorrow morning, but it appears that virgin 4.4 jetpack produced this seg fault on both nano and nx (which are same version, but different binary images)

i can confirm now that on any fresh new jetpack 4.4 jetson that python3 -c "import cv2; import numpy as np; blank_image = np.zeros((500,500,3), np.uint8); cv2.imshow('s', blank_image); cv2.waitKey(0)"

produces: Illegal instruction (core dumped)

I’m going to build opencv on the host(s) and retry re-confirm
