07.03.2019 · for more info my list contains tensors each tensor have different size for example the first tensor size is torch.Size([76080, 38]) the shape of the other tensors would differ in the second element for example the second tensor in the list is torch.Size([76080, 36])

04.11.2019 · Hi, I think torch.tensor — PyTorch 1.7.0 documentation and torch.as_tensor — PyTorch 1.7.0 documentation have explained the difference clearly but in summary, torch.tensor always copies the data but torch.as_tensor tries to avoid that! In both cases, they don’t accept sequence of tensors. The more intuitive way is stacking in a given dimension which you can …

You can directly convert python list to a pytorch Tensor by defining the dtype . For example, import torch a_list = [3,23,53,32,53] a_tensor ...

So we use torch.FloatTensor and we pass our py_list variable which contains our original Python list. And the result from this operation is going to be assigned to the Python variable pt_tensor_from_list. Let’s check what kind of object the Python variable pt_tensor_from_list is holding using the Python type operation, and we see that it is a class of torch.Tensor. type(pt_tensor_from_list)

Feb 06, 2020 · A simple option is to convert your list to a numpy array, specify the dtype you want and call torch.from_numpy on your new array. Toy example: some_list = [1, 10, 100, 9999, 99999] tensor = torch.from_numpy(np.array(some_list, dtype=np.int)) Another option as others have suggested is to specify the type when you create the tensor:

Jan 13, 2022 · 2. 3. Our New 2D Tensor from 2D List is: tensor ( [ [ 5, 10, 15, 20], [25, 30, 35, 40], [45, 50, 55, 60]]) As you can see, the torch.tensor () method also works well for the two-dimensional tensors. Now, let’s use shape (), size (), and ndimension () methods to return the shape, size, and dimensions of a tensor object.
