🐛 [Bug] Draw svg for flux model hangs

Bug Description

Whenever I try to draw the flux model, it hangs, I have to kill it.

KeyboardInterrupt

To Reproduce

Steps to reproduce the behavior:

with torch_tensorrt.dynamo.Debugger(
                "graphs",
                logging_dir=DEBUG_LOGGING_DIR,
                capture_fx_graph_after=["remove_num_users_is_0_nodes"],
                save_engine_profile=True,
                profile_format="trex",
                engine_builder_monitor=True,
            ):
                trt_gm = torch_tensorrt.dynamo.compile(
                    ep, inputs=dummy_inputs, **settings
                )

Expected behavior

Environment

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

• Torch-TensorRT Version (e.g. 1.0.0):
• PyTorch Version (e.g. 1.0):
• CPU Architecture:
• OS (e.g., Linux):
• How you installed PyTorch (conda, pip, libtorch, source):
• Build command you used (if compiling from source):
• Are you using local sources or building from archives:
• Python version:
• CUDA version:
• GPU models and configuration:
• Any other relevant information:

Additional context

Start with examples/apps/flux_demo.py:179 and py/torch_tensorrt/dynamo/lowering/passes/pass_manager.py:22, then trace the draw_fx_graph_pass call into pydot's create_svg shown in the traceback. Reproduce the Flux model compilation with the provided Debugger settings; done means SVG graph generation no longer hangs during compilation.
