[wasm]Error: Kernel 'Complex' not registered for backend 'wasm'

[axinging]

Case:

 it('complex', async () => {
    const real = tf.tensor1d([3, 30]);
    const imag = tf.tensor1d([4, 40]);
    const complex = tf.complex(real, imag);
    const res = tf.mul(complex, complex);
    expectArraysClose(await res.data(), [-7, 24, -700, 2400]);
  });

Error:

Hi, @axinging

Apologize for the delayed response and we're re-visiting our older issues and checking whether those issues got resolved or not as of now so May I know are you still looking for the solution or your issue got resolved ?

If issue still persists after trying with latest version of TFJs please let us know with error log and code snippet to replicate the same issue from our end ?

Could you please confirm if this issue is resolved for you ? Please feel free to close the issue if it is resolved ? Thank you!

Hi @gaikwadrahul8,

TFJS wasm backend does not support complex dtype and all kernels/ops for complex tensors. I'm going to work on that support later this year. If you see any issues related to complex on wasm backend please assign to me, thanks!
