description         A tensor contraction order optimizer.

long_description    Optimized einsum can significantly reduce the \
                    overall execution time of einsum-like expressions \
                    (e.g., np.einsum, dask.array.einsum, pytorch.einsum, \
                    tensorflow.einsum) by optimizing the expression's \
                    contraction order and dispatching many operations \
                    to canonical BLAS, cuBLAS, or other specialized \
                    routines. Optimized einsum is agnostic to the backend \
                    and can handle NumPy, Dask, PyTorch, Tensorflow, CuPy, \
                    Sparse, Theano, JAX, and Autograd arrays as well as \
                    potentially any library which conforms to a standard API.
