Hi, TVM.
When I test `resize2d` test case, I got a error.
The test case is modify in onnx/test_forward.py.
```
@tvm.testing.parametrize_targets
def test_resize(target, dev):
"""test_resize"""
def verify(ishape, oshape, scales, mode, coord_trans="asymmetric",
alpha=0.5, exclude=False):
nodes = [
make_constant_node("roi", onnx.TensorProto.FLOAT, (0,), []),
make_constant_node("scales", onnx.TensorProto.FLOAT,
(len(scales),), scales),
]
input_names = ["X", "roi", "scales"]
if oshape != []:
nodes.append(
make_constant_node("sizes", onnx.TensorProto.INT64,
(len(oshape),), oshape)
)
input_names.append("sizes")
nodes.append(
helper.make_node(
"Resize",
inputs=input_names,
outputs=["Y"],
mode=mode,
coordinate_transformation_mode=coord_trans,
cubic_coeff_a=alpha,
exclude_outside=exclude,
nearest_mode="round_prefer_ceil",
)
)
if oshape == []:
oshape = [round(dim * scale) for (dim, scale) in zip(ishape,
scales)]
graph = helper.make_graph(
nodes,
"resize_test",
inputs=[helper.make_tensor_value_info("X", TensorProto.FLOAT,
ishape)],
outputs=[helper.make_tensor_value_info("Y", TensorProto.FLOAT,
oshape)],
)
model = helper.make_model(graph, producer_name="resize_test")
verify_with_ort(
model,
[ishape],
[oshape],
use_vm=True,
opset=11,
freeze_params=True,
target=target,
dev=dev,
)
verify([1, 3, 320, 320], [1, 3, 96, 96], [] , "nearest", "half_pixel")
```
Just add a attr of `nearest_mode == round_prefer_ceil ` and use a
downsampling test case.
then I got a error result.
```

```
### Expected behavior
The result is correct
### Actual behavior
The result is not correct
### Environment
the tvm version is latest
@AndrewZhaoLuo @masahi Can you help me to have a look this question. thanks.
