In the configuration file, all steps of data preprocessing and the execution sequence thereof, data input paths, data output paths corresponding to the respective steps, and preprocessing scripts or programs are predefined. For example, in the schematic diagram of the configuration file shown in fig. 2, the defining preprocessing method includes N steps, numbered according to Step1, step2, … …, step N, where the data input path folder input, the data output path folder output, and the folder script of the data preprocessing script or program are respectively set. It will be appreciated that in general, the data output path of the previous step and the data input path of the next step are identical. The preprocessing script or program is provided by the user, and the user can adopt any programming language to realize according to the actual application of the user. However, the user must write the preprocessing script according to the agreed rules, i.e. the data input paths of the script or program are required to be parameterized and identical, and the data output paths are also required to be parameterized and identical.
For more flexibility, the pre-processing scripts or programs may be further standardized as entry scripts and subtask scripts or programs. The entry script is used for defining the execution sequence of the subtask script or program, and the subtask script or program is a series of subtask scripts or programs written according to preset rules and used for realizing the functions of the step. The basic content of the entry script is to call each script or program in the step to meet different requirements. In fig. 2, main.py is an entry Script, where both the entry Script and the subtask Script or program exist in the Script ipt path, and the subtask Script or program Script1 and Script2 are invoked by the entry Script.

In the configuration file, all steps of the data preprocessing, the execution sequence thereof, the data input path, the data output path, the entry script, and the subtask script or program corresponding to each step are predefined. The entry script is used to define the execution order of the subtask script or program. The basic content of the entry script is to call each script or program in the step, and judge whether to exit abnormally or continue the next step according to the return value. The subtask script or program is a series of subtasks script or program written according to preset rules to realize step functions. The number of subtask scripts or programs in each step and the adopted programming language are not required, and the subtask scripts or programs are completely written according to the own needs of users. The entry script solves the problems of different script realization languages, different numbers of scripts, different execution sequences and the like.
In order to enable a user to know the data preprocessing condition in time, manual polling is not needed, particularly after preprocessing is abnormal, the user is informed of timely processing, and the embodiment of the invention also configures the user address and sets prompt information to be fed back to the user through the user address when each step fails to execute or is executed successfully. The user address is a mailbox address.
S302, monitoring a path of the original data.
S303, calling an entry script of the first step after detecting that unprocessed original data exists, and executing a subtask script or program of the first step by the entry script.

S304, scanning the data input path of the Nth step, and calling the entry script of the Nth step to execute the subtask script or the program of the Nth step if unprocessed intermediate data exists.
S305, judging whether the execution fails, if yes, turning to step S309, otherwise, executing step S306.
S306, sending a step processing success notice to a preset user address.
It should be noted that, as an alternative, a success notification may not be sent to the user, but may be sent to a preset user address after all the steps of the preprocessing are performed successfully.
S307, deleting the processed intermediate data in the data input path of the step.
S308, judging whether the step N is the last step, if so, returning to the step S302, and executing the step S309.
S309, N accumulates 1, and returns to step S302.
S310, sending a step processing failure notice to a preset user address.
In the embodiment of the invention, the data input path paths of each step are scanned and processed one by one according to the preprocessed configuration file. As shown in fig. 2, the Step1/input path is scanned from Step1, new data is found, step 1/src/entry script (e.g. main. Py) is called to perform preprocessing, mail notification is sent after the processing is finished, step2 is processed, the Step2/input path is scanned, and the processing is sequentially performed until the last Step StepN. After the first round is finished, the second round of scanning is started, and the Step1/input path is scanned from the beginning, so that the cycle is repeated. In some preferred embodiments, in order to save disk space and improve scanning efficiency, after executing the preprocessing script or program corresponding to each step, the method further includes: and deleting the processed intermediate data under the data input path corresponding to each step.
In the embodiment of the invention, the data input path of each step is scanned in turn according to the execution sequence of each step preset in the configuration file; when unprocessed intermediate data exists in the data input path of a certain step, the corresponding entry script of the step is called to execute the subtask script or the program of the step, so that the data driving between the steps is realized.
Example III
As shown in fig. 4, the embodiment of the present invention is illustrated with face recognition.
Taking the face picture preprocessing required by face recognition as an example, one source of the face picture is a famous face captured on a network, the captured face belonging to the same person is stored in the same path, and the face model training can be performed only after four steps of face detection, face positioning, face calibration, face weight removal and the like are preprocessed aiming at the picture under the path, and the four steps of products have corresponding processing scripts or programs, but are all manual operation, and the invention can be applied according to the following steps to be automated.
The step S401 is the steps of face detection, face positioning, face calibration and face rearrangement.
Step S402, respectively predefining subtasks of each step, and writing an entry function of each step and a script or program of each subtask.
Specifically, the face detection step is divided into three steps of background modeling, foreground extraction and block mass selection. Firstly, modifying scripts or programs such as background modeling, foreground extraction, block selection and the like, and transmitting a face input path and a face output path as parameters to the programs or scripts. Secondly, writing an entry function, calling background modeling, foreground extraction, block selection and the like in sequence, entering the next step if each small step is successfully called, and reporting errors and notifying the user if the small step is unsuccessful. Thus, the face detection step is completed.
Similarly, face positioning, face calibration and face weight removal are continuously predefined respectively. To this end, the script or programming of all steps is completed.
Step S403, writing a configuration file of face recognition, and writing the predefined steps and the execution sequence thereof, the entry script, the subtask script or program of each step and the data input path and the data output path into the configuration file.
Specifically, step1 corresponds to face detection, determines an input path, an output path and an entry script, and if notification is to be sent, user address information, such as a mailbox address, needs to be defined. Similarly, step2 corresponds to face positioning, step3 corresponds to face calibration, and Step4 corresponds to face weight removal. So far, the configuration of the preprocessing configuration file is completed.
Step S404, deploying the configuration file, the entry script, the subtask script or the program of each step into the environment, and starting the data preprocessing process.
In addition, in the tuning process of model training, higher quality requirements may be put on the data, and more refined pretreatment is often performed. Taking face recognition as an example, the original face detection algorithm is based on traditional image processing, faces are detected according to the outlines, textures and the like of images, the faces detected under the scenes of complex background, strong illumination and the like are not accurate, and an MTCNN algorithm with higher precision is needed to be changed. The MTCNN algorithm comes from the Shenzhen advanced technology institute, qiao Yu teacher group. Consists of 3 network structures (P-Net, R-Net, O-Net). Propos Network (P-Net): the network structure mainly obtains candidate windows of the face area. Finer Network (R-Net): and carrying out regression and maximum value on the candidate windows, and merging the highly overlapped candidate frames. Output Network (O-Net): and 5-point positioning coordinates of the face are obtained. This requires modification of the automated preprocessing script, which can operate as follows.
And 1, adopting an MTCNN algorithm to write a new face detection program or script.
The entry function of the face detection step is modified accordingly.
And 2, stopping the face recognition preprocessing process, and simultaneously clearing the data in the intermediate state.
And 3, replacing script or program of the face detection step.
And 4, starting a face recognition preprocessing process.
In the embodiment of the invention, the human face is taken as an example for explanation, and similar image recognition also comprises vehicle recognition and license plate recognition, but the application is not limited to image recognition, and the method can be applied to preprocessing of artificial intelligent data training and big data cleaning of all data formats.
