请问为什么在训练完成后无法启动预测

[bailiancg]

在训练完成后我使用命令：python run_infer.py --param_path ./examples/cls_ernie_fc_ch_infer.json来启动预测， 但是报错缺失了文件 [Errno 2] No such file or directory: './output/cls_ernie_3.0_base_fc_ch_dy/save_checkpoints/checkpoints_step_200\infer_data_params.json' 但是在训练过程中我并没有生成这个json文件。

完整报错： INFO: 01-19 14:36:45: params.py:43 * 13200 ./output/cls_ernie_3.0_base_fc_ch_dy/save_checkpoints/checkpoints_step_200\infer_data_params.json Traceback (most recent call last): File "C:\Users\Zhang\Desktop\attend\ERNIE-ernie-kit-open-v1.0\ERNIE-ernie-kit-open-v1.0\applications\tasks\text_classification\run_infer.py", line 71, in inference = build_inference(inference_params_dict, dataset_reader, parse_predict_result) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\Zhang\Desktop\attend\ERNIE-ernie-kit-open-v1.0\ERNIE-ernie-kit-open-v1.0\applications\tasks\text_classification\run_infer.py", line 30, in build_inference inference = inference_class(params=params_dict, data_set_reader=dataset_reader, parser_handler=parser_handler) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\Zhang\Desktop\attend\ERNIE-ernie-kit-open-v1.0\ERNIE-ernie-kit-open-v1.0\applications\tasks\text_classification\inference\custom_inference.py", line 24, in init BaseInference.init(self, params, data_set_reader, parser_handler) File "C:\Users\Zhang\Desktop\attend\ERNIE-ernie-kit-open-v1.0\ERNIE-ernie-kit-open-v1.0\applications\tasks\text_classification../../..\erniekit\controller\inference.py", line 38, in init self.parser_input_keys() File "C:\Users\Zhang\Desktop\attend\ERNIE-ernie-kit-open-v1.0\ERNIE-ernie-kit-open-v1.0\applications\tasks\text_classification../../..\erniekit\controller\inference.py", line 106, in parser_input_keys param_dict = params.from_file(data_params_path) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\Zhang\Desktop\attend\ERNIE-ernie-kit-open-v1.0\ERNIE-ernie-kit-open-v1.0\applications\tasks\text_classification../../..\erniekit\utils\params.py", line 50, in from_file json_file = json.loads(evaluate_file(filename), strict=False) ^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\Zhang\Desktop\attend\ERNIE-ernie-kit-open-v1.0\ERNIE-ernie-kit-open-v1.0\applications\tasks\text_classification../../..\erniekit\utils\params.py", line 44, in evaluate_file with open(filename, "r") as evaluation_file: ^^^^^^^^^^^^^^^^^^^ FileNotFoundError: [Errno 2] No such file or directory: './output/cls_ernie_3.0_base_fc_ch_dy/save_checkpoints/checkpoints_step_200\infer_data_params.json'
