| # TODO: Is this doing something clever about unknown shapes? |
There was a problem hiding this comment.
I checked, they are not doing anything clever, simply set unknown dims to 8 and use whatever comes out of it

Nothing clever was going on, unknown dims were simply faked as having length 8 for JAX polymorphism export
A shortcut in the numpy implementation of einsum_path when there's nothing to optimize, creates a default path that can combine more than 2 operands. Our implementation only works with 2 or 1 operand operations at each step. https://github.com/numpy/numpy/blob/cc5851e654bfd82a23f2758be4bd224be84fc1c3/numpy/_core/einsumfunc.py#L945-L951
