Command Function

Displays the existing tuning data, which can be overall data or data of a specified round, and analyzes parameter importance.

Syntax

1
show [-h] {round,top,importance} ...

Parameter Description

Table 1 show subcommand parameters

Parameter

Option

Description

-h/--help

-

Displays the help information about the show subcommand.

round

-

Displays information about a specified round.

top

-

Displays the performance data of the first N rounds in descending order.

importance

-

Analyzes the importance of global parameters.

NOTE:

You can set this parameter to find what parameters can improve performance during multiple rounds of tuning. In the command output, a higher value in the importance(%) column indicates stronger correlation between the parameter and the tuning effect.
