OpDef &FormatMatchMode(FormatCheckOption option)

Parameters

Returns

OpDef operator definition. For details, see OpDef.

Constraints

If this API is not called, the input and output data in NCHW/NHWC/DHWCN/NCDHW/NCL format is converted into ND format by default.

Example

In the following example, the input x of the AddCustom operator supports only the NCHW format, and the input y supports only the NHWC format. You need to set FormatMatchMode to FormatCheckOption::STRICT. If FormatMatchMode is not set, the aclnn framework converts the input to the ND format and passes it to the tiling operator.
