Both TensorFlow and PyTorch have their own advantages as starting platforms to learn deep learning and AI. PyTorch is mainly used by researchers and Python enthusiasts, while TensorFlow is a preferred option in production for building large scale deep learning models. However, the latest releases have seen both PyTorch and TensorFlow converge towards a more similar profile. So, you can either stick to TensorFlow or PyTorch as your deep learning framework. You can check out this TensorFlow Tutorial by Intellipaat to learn TensorFlow framework.
