```python
class tensorplay.onnx.GraphBuilder(opset: int, name: str = 'tensorplay_model')
```

Accumulates ONNX nodes, initializers and unique value names.

```python
constant(value: Any, dtype: Any = None, name_hint: str = 'const') → str
```

Materialize a python/tensor constant as a cached initializer.

```python
op(op_type: str, inputs: Sequence[str], *, num_outputs: int = 1, name_hint: str | None = None, outputs: Sequence[str] | None = None, **attrs: Any) → Any
```

Emit one ONNX node and return its output name (or list of names).

```python
static_dims: Callable[[Value], Sequence[int | None] | None] | None
```

Per-axis extents of a value that the exported graph fixes, None
on the axes that vary at runtime.  Unset, every sampled extent is
taken as fixed.
