[NestedTensor](https://github.com/pytorch/nestedtensor) is a package to work with tensors of different sizes and lengths. It should be released soon, so I guess you might be using the nightly binary?

Anyway, I’m not sure if `.shape` should return this error or some `struct` containing different lengths.
