# ONNX104: initializer-missing-const-value

**Code:** `ONNX104`

**Name:** `initializer-missing-const-value`

**Severity:** error

**Category:** ir

**Target:** graph

**Fixable:** No

## Message

Initializer Value has no const_value set.

## Suggestion

Assign a tensor to the initializer's const_value, e.g. `value.const_value = ir.tensor(...)`.

## Details

In onnx_ir, initializers are Value objects stored in the graph's
initializers dict. Each initializer must have a `const_value` attribute
containing the actual tensor data. An initializer without const_value
cannot be serialized and indicates a malformed IR.
