 1. GLOG_v specifies the log level. The default value is 2, indicating the WARNING level. The values are as follows: 0: DEBUG; 1: INFO; 2: WARNING; 3: ERROR.
 2. When GLOG_logtostderr is set to 1, logs are output to the screen. If the value is set to 0, logs are output to a file. Default value: 1
 3. GLOG_log_dir=YourPath specifies the log output path. If GLOG_logtostderr is set to 0, value of this variable must be specified. If GLOG_log_dir is specified and the value of GLOG_logtostderr is 1, logs are output to the screen but not to a file. Logs of C++ and Python will be output to different files. The file name of C++ log complies with the naming rule of GLOG log file. Here, the name is `mindspore.MachineName.UserName.log.LogLevel.Timestamp`. The file name of Python log is `mindspore.log`.
-4. MS_SUBMODULE_LOG_v="{SubModule1:LogLevel1,SubModule2:LogLevel2,...}" specifies log levels of sub modules of MindSpore. The specified sub module log level will overwrite the global log level. The meaning of submodule log level is same as GLOG_v, the sub modules of MindSpore grouped by source directory is as the bellow table. E.g. when set `GLOG_v=1 MS_SUBMODULE_LOG_v="{PARSER:2,ANALYZER:2}"` then log levels of `PARSER` and `ANALYZER` are WARNING, other modules' log levels are INFO.

 1. GLOG_v 控制日志的级别，默认值为2，即WARNING级别，对应关系如下：0-DEBUG、1-INFO、2-WARNING、3-ERROR。
 2. GLOG_logtostderr 值设置为1时，日志输出到屏幕；值设置为0时，日志输出到文件。默认值为1。
 3. GLOG_log_dir=YourPath 指定日志输出的路径。若GLOG_logtostderr的值为0，则必须设置此变量。若指定了GLOG_log_dir且GLOG_logtostderr的值为1时，则日志输出到屏幕，不输出到文件。C++和Python的日志会被输出到不同的文件中，C++日志的文件名遵从GLOG日志文件的命名规则，这里是`mindspore.机器名.用户名.log.日志级别.时间戳`，Python日志的文件名为`mindspore.log`。
