URL: https://github.com/apache/tvm/issues/13154

   The unittest `test_pipeline_executor.py` runs right. But when I change [Line 
473](https://github.com/apache/tvm/blob/main/tests/python/relay/test_pipeline_executor.py#L473)
 to `datas.append(np.random.randn(*dshape))`, the unittest will fail as 
following:
   ```
           np.testing.assert_allclose(actual.shape, desired.shape)
   >       np.testing.assert_allclose(actual, desired, rtol=rtol, atol=atol, 
verbose=True)
   E       AssertionError: 
   E       Not equal to tolerance rtol=1e-07, atol=1e-07
   E       
   E       Mismatched elements: 9 / 9 (100%)
   E       Max absolute difference: 1.34077008
   E       Max relative difference: 2.36375847e+44
   E        x: array([[-1.34077 ,  1.324932, -0.255464],
   E              [-0.332742,  0.648831, -0.631121],
   E              [ 0.561325, -1.151209, -0.033365]])
   E        y: array([[0.e+00, 6.e-45, 0.e+00],
   E              [0.e+00, 3.e-45, 0.e+00],
   E              [0.e+00, 0.e+00, 0.e+00]], dtype=float32)
   
   python/tvm/testing/utils.py:114: AssertionError
   ```
   So I want to confirm that Multi-batch has not be supported in Pipeline 
Executor yet?Thanks for your advice @huajsj @comaniac
