There are a few distinct differences between Tensorflow and Pytorch when it comes to data compuation. 01 Tensor Both TensorFlow and PyTorch are based on the concept "Tensor". However, the term "Variable" in each framework is used in different way. TensorFlow If you want to declare mutable variable (weight and bias): use tf.Variable. For example, torch.FloatTensor.abs_ () computes the absolute value in-place and returns the modified tensor, while torch.FloatTensor.abs () computes the result in a new tensor. Note To change an existing tensor's torch.device and/or torch.dtype, consider using to () method on the tensor. Warning.

Layers in CNN have several parameters: depth, stride, and padding . Depth is the number of filters to train in the layer, stride is the number of pixels which the filter should process during convolution, and padding is a matter of whether or not padding should be carried out and what method should be used for it.

If a FloatTensor is provided, it will be added to the attention weight. [src/tgt/memory]_key_padding_mask provides specified elements in the key to be ignored by the attention. If a ByteTensor is provided, the non-zero positions will be ignored while the zero positions will be unchanged.
