Fix TypeInferenceError

✅ Solution

TypeInferenceError in diffusers ONNX conversion usually arises due to dynamic shapes not being fully defined during tracing. Fix this by explicitly specifying static input shapes (e.g., using `static_shapes=True` where available or manual shape definition in `torch.onnx.export`) to allow proper type inference during ONNX export; alternatively, set dynamic axes within the `dynamic_axes` parameter of `torch.onnx.export` to guide shape inference.
