Symbolic Shape infer fails on onnx file without much logs

[aaditya-srivathsan]

Describe the issue

I have a DINO model with a SWIN backbone that i want to try using certain TRT optimizations on the onnx model itself. I am trying to use the symbolic shape infer since the first effort gave me this error

After running the shape infer command here, the conversion fails without much indication as to why
