WebApr 7, 2024 · PyTorch, regardless of rounding, will always add padding on all sides (due to the layer definition). Keras, on the other hand, will not add padding at the top and left of the image, resulting in the convolution starting at the original top left of the image, and not the padded one, giving a different result. WebMar 22, 2024 · Because of this, converting a NumPy array to a PyTorch tensor is simple: import torch import numpy as np x = np.eye (3) torch.from_numpy (x) # Expected result # tensor ( [ [1., 0., 0.], # [0., 1., 0.], # [0., 0., 1.]], dtype=torch.float64) All you have to do is use the torch.from_numpy () function.
