Describe the current behavior
Given the "t1": [[-1767738612.8308272,1342651338.1728053]], "t2": [[-1069397745.6943247,-1040119386.9828408],[630839119.41397,-1766313500.9227078]], tf.dot(t1,t2) return [ [ 2737412593109958700, -532884082837684200 ] ] on the CPU backend. However, tf.dot(t1,t2) return [[2737412867987865600, -532884048477945860]] on the WebGL backend and return [[2737412867987865600, -532884082837684200]] on Wasm, and tensorflow backends.
Output:
Describe the expected behavior
The output should be consistent across all backends.
Standalone code to reproduce the issue
