onnxruntime推理出错

[youwh-PIRI]

Hello, this error occurred when I was reasoning on onnxruntime. Have you ever encountered it？Thank you very much if you can reply！

onnxruntime.capi.onnxruntime_pybind11_state.InvalidGraph: [ONNXRuntimeError] : 10 : INVALID_GRAPH : Load model from /home/youwh/ywh/efficientDet--ONNX/convert/efficientdet-d1-voc.onnx failed:This is an invalid model. Error in Node: : Node () has input size 1 not in range [min=2, max=3].

@youwh-PIRI Sorry for not familiar with onnxruntime.

yes.
when I try to use onnx-simplifier. The same error occurred.
looks like onnx checker can not accept current model format.

I also came across with the "Invalid Feed" error, here is my solution, before testing with onnxruntime_test, I use onnx optimize the onnx model, after "eliminate_unused_initializer" optimization, the onnxruntime_test passed. Hope this solution is usefull for you.

import onnx
from onnx import optimizer
def opt(original_model):
    op = ["eliminate_unused_initializer"]
    optimized_model = optimizer.optimize(original_model, op)
    onnx.save(optimized_model, "efficientdet-d0-opt.onnx")
