Running the save_model.py code on Nvidia Jetson TX2 with Jetpack 4.4.1 installed, python3.6, Cuda 10.2.

This seems to be an issue specific to Jetson boards that occurs when tensorflow is imported before opencv. Adding the line:

import cv2
import tensorflow as tf

to the beginning of the file resolved this issue for me. Just documenting it here in case anyone else has this issue. Seems to be related to https://github.com/opencv/opencv/issues/14884

export LD_PRELOAD=/usr/lib/aarch64-linux-gnu/libgomp.so.1 Add this line and u are good to go

Worked for me, thanks. @xanthan011
