+    The logger will be initialized if it has not been initialized. By default a

+        log_file (str | None): The log filename. If specified, a FileHandler

+        log_level (int): The root logger level. Note that only the process of
+            rank 0 is affected, while other processes will set the level to
+            "Error" and be silent most of the time.
