Convert a list of tensors to tensors of tensors pytorch

I have this code:

import torch

list_of_tensors = [ torch.randn(3), torch.randn(3), torch.randn(3)]
tensor_of_tensors = torch.tensor(list_of_tensors)

I am getting the error:

ValueError: only one element tensors can be converted to Python scalars

How can I convert the list of tensors to a tensor of tensors in pytorch?

Answer

Here is a solution:

tensor_of_tensors = torch.stack((list_of_tensors))
print(tensor_of_tensors) #shape (3,3)
