PyTorch is a Python based scientific package which provides a replacement of NumPy ndarrays as Tensors which takes utmost advantage of the GPUs. Another positive point about PyTorch framework is the speed and flexibility it provides during computing. PyTorch is an efficient alternative of working with Tensors. PyTorch is mainly embraced by the Data Science community due to its capability to conveniently define neural networks. Let’s see this computational package in action in this lesson.
