The GraviPy module includes the tensor classes Christoffel, Riemann, Ricci, Einstein and Geodesic. The Christoffel, Riemann and Ricci tensors depend only on the metric. Therefore, they all have very ...

For example, tensor t2 could have been created by the statement t2 = T.LongTensor([1,2,3,4]).to(device). Dealing with the crazy number of aliases and default parameter values in PyTorch is a ...

If you are adept at Python and remember your high school algebra, you might enjoy [Oliver Holloway’s] tutorial on getting started with Tensorflow in Python. [Oliver] gives links on how to do the ...
