--calibration_config

Description

Sets the path (including the file name) of the simplified configuration file for PTQ.

Include this option if you have created a simplified configuration file for PTQ (that is, you control which layers to be quantized or not to be quantized).

This option is mutually exclusive with --batch_num.

Argument

Argument: path (including the file name) of the simplified configuration file.

Format: The path (including the file name) can contain letters, digits, underscores (_), hyphens (-), and periods (.).

Default: none.
