问题描述：
使用MindSpore Lite模型转换工具，配置全量化（FULL_QUANT）之后，会报错。
配置信息
converter_lite --fmk=ONNX --modelFile=RetinaFace.onnx --outputFile=RetinaFace_full_quant --inputDataFormat=NCHW --fp16=off --configFile=full_quant_params.ini
full_quant_params.ini配置如下
[common_quant_param]
quant_type=FULL_QUANT
[data_preprocess_param]
calibrate_path=input_name_1:./calibrate_input
calibrate_size=30
input_type=IMAGE
normalize_mean=[104, 117, 123]
resize_width=320
resize_height=320
resize_method=LINEAR
错误信息如下

请问这里的“Cant find input:input”是找不到模型的输入吗？还是什么呢，希望知晓的朋友给予解答。
解答：
配置文件calibrate_path应该改为模型的输入的名字input
