Bug Description

when i use torch_tensorrt.compile transformer module with dynamic_shapes, it will occur this error,

To Reproduce

def test_compile_v1(): model = AutoModel.from_pretrained('bert-base-case', use_cache=False) # Enabled precision for TensorRT optimization enabled_precisions = {torch.half}

# Whether to print verbose logs
debug = False

# Workspace size for TensorRT
workspace_size = 20 << 30

# Maximum number of TRT Engines
# (Lower value allows more graph segmentation)
min_block_size = 7

# Operations to Run in Torch, regardless of converter support
torch_executed_ops = {}

input_ids = torch.randint(2, 100, (1, 16), device=DEVICE)
torch._dynamo.mark_dynamic(input_ids, 1, min=2, max=512)
trt_model = torch_tensorrt.compile(
    model,
    ir='torch_compile',
    inputs=input_ids,
    enabled_precisions=enabled_precisions,
    debug=debug,
    workspace_size=workspace_size,
    min_block_size=min_block_size,
    torch_executed_ops=torch_executed_ops,
)

out1 = trt_model(input_ids)
print(out1)
