Function Documentation

◆ _get_generate_func()

Callable pxd.background_generator.models._get_generate_func ( str  model)
private

Helper function that imports and returns the function generate from the Python module named as model and assumed to be located in the package pxd.background_generator.models.

An error is raised if the Python module named as model:

  • does not exist,
  • does not contain the function generate.
Parameters
modelModel name and the name of the corresponding Python module implementing the model

Definition at line 55 of file __init__.py.

55 def _get_generate_func(model: str) -> Callable:
56  func = None
57  try:
58  func = import_module(f".{model}", __name__).generate
59  except AttributeError as exc:
60  exc.msg = f"please define the generation function for {model!r}"
61  raise
62  except ModuleNotFoundError as exc:
63  exc.msg = f"the selected model {model!r} is not implemented"
64  raise
65  return func

◆ _get_model_cls()

Type pxd.background_generator.models._get_model_cls ( str  model)
private

Helper function that imports and returns the class Model from the Python module named as model and assumed to be located in the package pxd.background_generator.models.

An error is raised if the Python module named as model:

  • does not exist,
  • does not contain the class Model.
Parameters
modelModel name and the name of the corresponding Python module implementing the model

Definition at line 31 of file __init__.py.

Variable Documentation

◆ MODELS

tuple MODELS
Initial value:
1 = (
2  "convnet",
3  "resnet",
4 )

Container for names of generator models that are available for selection.

Each model name is assumed to match a corresponding Python module that is located in the package pxd.background_generator.models and implements the specific model, i.e. defines a:

  • class Model,
  • function generate.

The class Model must inherit from the base class torch.nn.Module.

The generation function generate specific to a model is assumed to act on a model instance and produce an output of type torch.Tensor that is of shape (40, 250, 768) and contains values of type torch.uint8 in the interval $ [0, 255] $. Each index in the first axis of the output tensor is assumed to correspond to the PXD sensor specified by the VxdID arguments in pxd.background_generator.VXDID_ARGS at the same index.
