python - Is there any package like einsum which could with symmetry?

Question

I have some tensor contractions, e.g., A[abcd] B[abcd] = C, where A[abcd]=A[badc]and B[abcd]=B[badc].

I checked the manual of einsum https://numpy.org/doc/stable/reference/generated/numpy.einsum.html, but did not find any option of symmetry.

Is there any option in einsum or other package can handle this symmetry, preferably by python/julia, that could make the contraction faster?
