# ONNX034: graph-input-missing-type

**Code:** `ONNX034`

**Name:** `graph-input-missing-type`

**Severity:** error

**Category:** spec

**Target:** graph

## Message

Graph input is missing type information.

## Suggestion

Set the type on all graph inputs, e.g. `value.type = ir.TensorType(ir.DataType.FLOAT)`.

## Details

Per the ONNX specification, graph inputs must have type information.
Runtimes use these types to allocate memory and validate feeds.
