This is reproducible with jax-metal 0.0.5. The lowering pattern need to be expanded to handle contracting_dimensions size > 1. To workaround, could you make the below changes and give it a try:
a = np.random.rand(11, 12, 13, 11, 12).reshape(132, 13, 11, 12)
b = np.random.rand(11, 12, 13).reshape(132, 13)
#subscripts = 'ijklm,ijk->lmk'
subscripts = 'iklm,ik->lmk'
It generates matching result on my side.
Can you pls provide the steps and the script to reproduce it?
The issue has been fixed in jax-metal 0.0.7.
