GB10 (ASUS Ascent GX10) can't run Build.TRT.Engine_SDXL_Base of comfyui_tensorrt #11707
Description
Custom Node Testing
- I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)
Expected Behavior
I attempted to run Build.TRT.Engine_SDXL_Base on an ASUS Ascent GX10 using ComfyUI v0.8.0 and v0.7.0, but both versions failed.
Actual Behavior
I attempted to run Build.TRT.Engine_SDXL_Base on an ASUS Ascent GX10 using ComfyUI v0.8.0 and v0.7.0, but both versions failed.

# ComfyUI Error Report
## Error Details
- **Node ID:** 2
- **Node Type:** STATIC_TRT_MODEL_CONVERSION
- **Exception Type:** torch.onnx._internal.exporter._errors.TorchExportError
- **Exception Message:** Failed to export the model with torch.export. �[96mThis is step 1/3�[0m of exporting the model to ONNX. Next steps:
- Modify the model code for `torch.export.export` to succeed. Refer to https://pytorch.org/docs/stable/generated/exportdb/index.html for more information.
- Debug `torch.export.export` and submit a PR to PyTorch.
- Create an issue in the PyTorch GitHub repository against the �[96m*torch.export*�[0m component and attach the full error stack as well as reproduction scripts.
## Exception summary
<class 'torch._dynamo.exc.UserError'>: Detected mismatch between the structure of `inputs` and `dynamic_shapes`: `inputs[3]` is a <class 'tuple'>, but `dynamic_shapes[3]` is a <class 'dict'>
For more information about this error, see: https://pytorch.org/docs/main/generated/exportdb/index.html#dynamic-shapes-validation
The error above occurred when calling torch.export.export. If you would like to view some more information about this error, and get a list of all other errors that may occur in your export call, you can replace your `export()` call with `draft_export()`.
(Refer to the full stack trace above for more information.)

## Exception summary
<class 'torch._dynamo.exc.UserError'>: Detected mismatch between the structure of `inputs` and `dynamic_shapes`: `inputs[3]` is a <class 'tuple'>, but `dynamic_shapes[3]` is a <class 'dict'>
For more information about this error, see: https://pytorch.org/docs/main/generated/exportdb/index.html#dynamic-shapes-validation
The error above occurred when calling torch.export.export. If you would like to view some more information about this error, and get a list of all other errors that may occur in your export call, you can replace your `export()` call with `draft_export()`.
