Load TensorFlow Models Using OpenCV

Background : It is always a daunting task with Tensorflow sessions and standard handling of a typical Tensorflow model when you want to run inference. However, if you are an experienced developer you may also quickly go through these steps because you are already aware about how to use Tensorflow to run inference on your model.

Installing OpenCV with contrib extra modules from source on Fedora Linux

Why the sudden need? I have mostly used the OpenCV library as available from pip or by installing wheel until I required some more essential features that are not available from those pre built binaries.
