প্যারামিটার:

• eri (Tensor | ndarray | SparseArray) -- the 2-dimensional tensor to fold.

• validate (bool) -- when set to False, the requirements of eri are not validated.

রিটার্নস:

An 8-fold symmetric tensor.

রেইজেস:

• ValueError -- if eri is not 2-dimensional.

• ValueError -- if eri is not a symmetric tensor.
