Function Usage

Sets the symbol identifier of the input, which is used for dynamic shape inference or symbolic expression to establish the symbol association between the input and output.

Prototype

IrInputDefV2 &SymbolId(const char_t *symbol_id)

Parameters

Parameter	Input/Output	Description
symbol_id	Input	Symbol ID of the input tensor, which is used for: Dynamic shape scenario: It identifies dynamic dimensions (such as batch_size, height, and width). Symbolic inference: It establishes the symbolic relationship between the input and output (similar to the variable symbol in mathematical formulas). Shape association: When multiple tensors share the same symbol, the shape relationship between them can be inferred.
