Computer Vision tasks: I train models to to object detection, image classification, semantic segmentation... export the model, load the trained model in C++ and run inference.

Or generative models: same workflow (python definition and train. Export and use in other languages).

I use Tensorflow basically everyday. I use pytorch only when I read a model implemented in this framework to reimplement it in Tensorflow (in order to use all the tools I developed to simplify the train to shipping to production phases)
