运行rockchip提供的Python freeze_inshape_for_onnx_model.py以固定shape，显示有236种输入，236不清楚是如何得来的


Python freeze_inshape_for_onnx_model.py --onnx_file_path nanodet_sim.onnx --output_path model_out.onnx --inputs_shape 1,3,768,576#2,3,768,576

更新到rknn_toolkit-1.7.1-cp36-cp36m-win_amd64.whl，出Loading dynamic inputs model is not support, please fix it first，请问对于动态输入层有什么解决方案吗
