Describe the current behavior
Given the "a":[[[[692093061.0947313,797688219.5022278]]],[[[-1668064714.535003,1419422926.3580394]]]],"b":[[-318504117.74568224,888231962.4587994],[-1840707687.672637,1053049392.4807925]], tf.matMul(a,b) return different results across all backends.
Output:
Describe the expected behavior
The output should be consistent across all backends.
Standalone code to reproduce the issue
Provide a reproducible test case that is the bare minimum necessary to generate
the problem. If possible, please share a link to Colab/CodePen/any notebook.
