Source: https://www.tensorplay.cn/docs/generated/tensorplay.distributed.device_mesh.init_device_mesh.html

```python
tensorplay.distributed.device_mesh.init_device_mesh(device_type: str, mesh_shape: tuple[int, ...], *, mesh_dim_names: tuple[str, ...] | None = None, backend_override=None) → DeviceMesh
```

This creates a DeviceMesh with an n-dimensional array layout, where n
is the length of mesh_shape. If mesh_dim_names is provided, each
dimension is labeled as mesh_dim_names[i].

> **Note**
>
> Follows SPMD: ensure mesh_shape is identical across all ranks.

Example:

```
>>> mesh_1d = init_device_mesh("cuda", mesh_shape=(8,))
>>> mesh_2d = init_device_mesh("cuda", mesh_shape=(2, 8),
...                             mesh_dim_names=("dp", "tp"))
```
