RuntimeError: Op Execution Error: /Slice(Type: Slice, Num of Input: 5, Num of Output: 1)

我在量化一个多输入模型：

dataset = CaliData(datapath, bs)
dataloader = data.DataLoader(dataset, batch_size=bs)
with ENABLE_CUDA_KERNEL():
    quantized = quantize_torch_model(
        model=model, calib_dataloader=dataloader,
        calib_steps=32, input_shape=None,inputs = next(iter(dataloader)),
        collate_fn=collate_fn, platform=PLATFORM, setting=QS,
        onnx_export_file='output.onnx', device=DEVICE, verbose=0)

报错如下：

[Warning] Unexpected input value of operation /Slice, recieving "None" at its input 0

The above exception was the direct cause of the following exception:

不知道哪里错了，求大佬指点迷津,本人菜鸡初学者一枚
