WebIn addition to Scalars, ATen also allows Tensorobjects to be zero-dimensional. These Tensors hold a single value and they can be references to a single element in a larger Tensor. They can be used anywhere a They are normally created by operators like selectwhich reduce the dimensions of a Tensor.
