No, as you noticed PyTorch infers dtype from input data only.. In your case, as numpy has it's default set to np.float64 (regardless of system and architecture) PyTorch will infer it's analogous torch.float64, so it's more of a problem with starting from numpy (and you can't set different default dtype).. In pytorch you usually go for torch.float32 (and it is the default), eventually torch ...
