🐛 [Bug] Encountered bug when using Torch-TensorRT

Bug Description

https://github.com/pytorch/TensorRT/blob/main/examples/dynamo/mutable_torchtrt_module_example.py
I replaced hugging face whisper model instead of diffusion model

To Reproduce

import numpy as np
import torch
import torch_tensorrt as torch_trt
from transformers import AutoModelForSpeechSeq2Seq, AutoProcessor, pipeline
#from datasets import load_dataset
from peft import PeftModel
#import torchvision.models as models

np.random.seed(5)
torch.manual_seed(5)
inputs = [torch.rand((1, 3, 224, 224)).to("cuda")]

%%

Initialize the Mutable Torch TensorRT Module with settings.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

device = "cuda:0" if torch.cuda.is_available() else "cpu"
torch_dtype = torch.float16

model_id = "distil-whisper/distil-large-v3"

with torch.no_grad():
settings = {
"use_python_runtime": True,
"enabled_precisions": {torch.float16},
"debug": True,
"make_refitable": True,
}

base_model = AutoModelForSpeechSeq2Seq.from_pretrained(
model_id, 
torch_dtype=torch_dtype, 
low_cpu_mem_usage=True,
)

base_model.eval().to(device)

#model = models.resnet18(pretrained=True).eval().to("cuda")
mutable_module = torch_trt.MutableTorchTensorRTModule(base_model, **settings)

Steps to reproduce the behavior:

1.Please run above code

Environment

Build information about Torch-TensorRT can be found by turning on debug messages

• Torch-TensorRT Version : 12.4
• PyTorch Version : 2.5.0.dev20240830+cu124
• CPU Architecture: x86
• OS (e.g., Linux): ubuntu
• How you installed PyTorch (conda, pip, libtorch, source): nightly install
• Python version: 3.10
• CUDA version: 12.4
• GPU models and configuration: A100 80G

Start with examples/dynamo/mutable_torchtrt_module_example.py and reproduce the reported Whisper model setup. Read the compilation path in torch_tensorrt/dynamo/runtime/_MutableTorchTensorRTModule.py, especially the export call shown in the traceback; done means the reported model no longer fails there, with an appropriate regression check identified.
