vin.encoders.pointnext_utils

Utility helpers for the optional PointNeXt VIN encoder.

aria_nbv.vin.encoders.pointnext.PointNeXtSEncoder wraps an OpenPoints PointNeXt-S model for semidense point-cloud context. This sidecar owns the unstructured OpenPoints/checkpoint glue so the torch.nn.Module implementation can stay focused on module lifecycle and tensor contracts.

1.1 Functions

Name	Description
extract_point_encoder_tensor	Return the first tensor-like feature payload from an OpenPoints output.
load_checkpoint_strict	Load an OpenPoints-style checkpoint with strict PyTorch key matching.
load_pointnext_cfg	Load a PointNeXt/OpenPoints YAML config with openpoints.utils.EasyConfig.

1.1.1 extract_point_encoder_tensor

vin.encoders.pointnext_utils.extract_point_encoder_tensor(output)

Return the first tensor-like feature payload from an OpenPoints output.

1.1.1.1 Parameters

Name	Type	Description	Default
output	Any	Tensor, mapping, tuple, or list returned by an external point encoder. OpenPoints variants commonly use keys such as feat or features but checkpoint/model wrappers are not fully uniform.	required

1.1.1.2 Returns

Name	Type	Description
	Tensor	The first torch.Tensor feature payload found.

1.1.1.3 Raises

Name	Type	Description
	TypeError	If no tensor payload can be located.

1.1.2 load_checkpoint_strict

vin.encoders.pointnext_utils.load_checkpoint_strict(model, checkpoint_path)

Load an OpenPoints-style checkpoint with strict PyTorch key matching.

1.1.2.1 Parameters

Name	Type	Description	Default
model	nn.Module	PointNeXt module built by OpenPoints.	required
checkpoint_path	Path	Path to a checkpoint containing a state dict directly or under common wrapper keys such as model or state_dict.	required

1.1.2.2 Raises

Name	Type	Description
	RuntimeError	If the checkpoint does not contain a dictionary state payload after unwrapping common OpenPoints keys.

1.1.3 load_pointnext_cfg

vin.encoders.pointnext_utils.load_pointnext_cfg(cfg_path)

Load a PointNeXt/OpenPoints YAML config with openpoints.utils.EasyConfig.

1.1.3.1 Parameters

Name	Type	Description	Default
cfg_path	Path	Absolute path to the OpenPoints YAML configuration file.	required

1.1.3.2 Returns

Name	Type	Description
	Any	Parsed OpenPoints config object.
