How to traverse the tensor elements in the list and concatenate them all

hello everyone:
If the list elements are all composed of tensors of the same dimension,
such as list = [a,b,c],a=b=c = torch.randn(6, 3, 10), how can I expand every element in the list adding each element in the last dimension, for example a convert to (6,1,3,10), a = b =c = torch.randn(6,1,3,10). finally， I can acquire (6,3,3,10)

sorry。 the torch.stack can be down
