Pytorch double tensor to float tensor
Did you know?
Webp_tensor should be a tensor containing probabilities to be used for drawing the binary random number. The i t h \text{i}^{th} i t h element of self tensor will be set to a value sampled from Bernoulli (p_tensor[i]) \text{Bernoulli}(\texttt{p\_tensor[i]}) Bernoulli (p_tensor[i]). self can have integral dtype, but p_tensor must have floating ... WebJul 13, 2024 · When learning a tensor programming language like PyTorch or Numpy it is tempting to rely on the standard library (or more honestly StackOverflow) to find a magic function for everything. But in practice, the tensor language is extremely expressive, and you can do most things from first principles and clever use of broadcasting.
