🐛 Bug

I get an error

• reigster_buffer in Module
• onnxruntime on onnx from torch.onnx.export

To Reproduce

Steps to reproduce the behavior:

1. code example

import torch

# init module
class MyModule(torch.nn.Module):
    def __init__(self):
        super(MyModule, self).__init__()
        self.register_buffer("rb", torch.randn(1, 1, 3, 1, 1)) 
        # you can run with the workaround
        # self.rb = torch.randn(1, 1, 3, 1, 1)

    def forward(self, x):
        x += self.rb[0]
        return x

torch_model = MyModule().eval()

# torch.onnx.export
torch.onnx.export(torch_model,
        torch.randn(1, 3, 224, 224),
        "./tmp.onnx",
        input_names=["inputs"],
        output_names=["outputs"],
        dynamic_axes={"inputs": {0: "batch", 2: "height", 3: "width"}, "outputs": {0: "batch", 1: "class", 2: "height", 3: "width"}},
        opset_version=11,
        export_params=True)

# onnxruntime
import os
import numpy as np
import onnxruntime
from onnxruntime.datasets import get_example

onnx_model = get_example(os.path.join(os.getcwd(), "tmp.onnx"))
sess = onnxruntime.InferenceSession(onnx_model)
inputs = np.random.randn(1, 3, 224, 224).astype(np.float32)
onnx_out = sess.run(None, {"inputs": inputs})
