rand It returns a tensor filled with Random floats from a uniform distribution on the interval [0, 1]. Uniform distribution on [0, 1] means : Every number between 0 and 1 has an equal probability of being selected. It doesn't mean the numbers will be evenly spaced or look "uniform" when you look at a few samples. For example, torch.rand(4)=> tensor([0.7529, 0.8579, 0.6870, 0.0051]) Each of these..

When model uses specific layers/part-Dropouts Layers, BatchNorm Layers etc, it can be turned on during the train mode, but it needs to be turned off during the evaluation mode. model.train() model.eval() Sets model in training mode: activates specific layers/part-Dropout layers etc normalisation layers1 use per-batch statistics Sets model in evaluation (inference) mode: de-activates Dropout laye..

view It merely creates a view of the original tensor. Same function as reshape in numpy. -1 : It means I am not sure so I will let pytorch to decide the dimension. torch.FloatTensor([[[1.,2.],[3.,4.]],[[5.,6.],[7.,8.]]]) >>> tensor([[[1., 2.], [3., 4.]], [[5., 6.], [7., 8.]]]) t.view([-1,2]) >>> tensor([[1., 2.], [3., 4.], [5., 6.], [7., 8.]]) a=torch.randn(1,2,3,4) a >>> tensor([[[[ 0.3861, -0...

contiguous Returns a contiguous in memory tensor containing the same data as self tensor. If self tensor is already in the specified memory format, this function returns the self tensor. Let's just define two tensors that shape are same. a = torch.randn(3, 4) a.transpose_(0, 1) b = torch.randn(4, 3) # both tensor shape is (4, 3) print(a) >>> tensor([[-0.7290, 0.7509, 1.1666], [-0.9321, -0.4360, ..
