While using the pass eliminate_duplicate_initializer to optimize the model Faster R-CNN R-50-FPN-qdq of opset=12 from ONNX Model Hub, I encounter the following error:

File "<path_to_onnx_optimizer>/onnxoptimizer/main.py", line 15, in \n main()\n File "<path_to_onnx_optimizer>/onnxoptimizer_main.py", line 76, in main\n model = onnxoptimizer.optimize(model=model, passes=passes, fixed_point=args.fixed_point)\n File "<path_to_onnx_optimizer>//onnxoptimizer/init.py", line 46, in optimize\n optimized_model_str = C.optimize(model_str, passes)\nRuntimeError: <path_to_onnx_optimizer>/onnxoptimizer/third_party/onnx/onnx/common/ir.h:1372: eraseOutput: Assertion "outputs_[i]->uses().empty()" failed.'
