[mlnode] Logging module, shut down function and the fixing of a bug about multi process training
Description
Logging module, shut down function and the fixing of a bug about multi process training We have developed new functions for the mlnode module of IoTDB, which mainly includes the following three parts:
Content
Logging module
Developed a logging module for mlnode, supporting standard function calls and localized log information for multi-process security
Shut down function
Completed the addition of the mlnode shutdown function, and implemented the direct shutdown of the mlnode main process based on the port number on the Linux system
Bug fixing
Fixed the issue involved in related work, which is that the original process pool does not support creating nums_ Issues with worker subprocesses
Usage
Logging module
We provide 5 levels of functions including debug, info, warn, error, and the module can localize logs according to the log level. In subsequent development, we only need to use a form similar to calling the Python standard logging module to use it.
Stop function
Since our start function is designed in the form of pip package, our stop function is developed in a similar form. If user start the mlnode in a terminal, we can stop the node in another one with the command "mlnode stop".
