In the previous post, we learned about one-dimensional tensors in PyTorch and applied some useful tensor operations. In this tutorial, we’ll apply those operations to two-dimensional tensors using the PyTorch library. WebPytorch tensors are similar to numpy arrays, but can also be operated on CUDA-capable Nvidia GPU. Numpy arrays are mainly used in typical machine learning algorithms (such as k-means or Decision Tree in scikit-learn) whereas pytorch tensors are mainly used in deep learning which requires heavy matrix computation. robert richter obituary
