**Header:** `ClikaRT/graph/compile.h`

One axis declared dynamic ahead of capture, the zero-re-capture road for an axis known to vary call to call (a batch size, a sequence length). [`input`](./DynamicAxis.md#input) selects by input name (a signature name, or the positional default "input\_0", "input\_1", …); empty applies to every input that has the axis. A non-empty [`name`](./DynamicAxis.md#name) also names the dimension: the same name on two axes declares the same size, exactly as [`spec::TensorSpec::dim_names`](../spec/TensorSpec.md#dim_names).
