…='optimal' (numpy#31354) It replaces the expression out[:] found in bmm_einsum() with the more universal out[...], which is also valid for a 0-dimensional out. TestEinsum.test_einsum_misc() in numpy/_core/tests/test_einsum.py has been extended. Co-authored-by: Sebastian Berg <sebastian@sipsolutions.net>
