hi
i try to simplify the .onnx

Simplifying...
Traceback (most recent call last):
File "/home/ubuntu/miniconda3/envs/efficientformer/bin/onnxsim", line 8, in
sys.exit(main())
File "/home/ubuntu/miniconda3/envs/efficientformer/lib/python3.8/site-packages/onnxsim/onnx_simplifier.py", line 489, in main
model_opt, check_ok = simplify(
File "/home/ubuntu/miniconda3/envs/efficientformer/lib/python3.8/site-packages/onnxsim/onnx_simplifier.py", line 199, in simplify
model_opt_bytes = C.simplify(
onnx.onnx_cpp2py_export.shape_inference.InferenceError: [ShapeInferenceError] (op_type:Conv, node name: Conv_339): [ShapeInferenceError] Inferred shape and existing shape differ in rank: (4) vs (0)

and then i output the shape of my seg onnx

Looking forward to your answer
