monai.deploy.operators.NiftiDataLoader¶
- class monai.deploy.operators.NiftiDataLoader(fragment, *args, input_path, **kwargs)[source]¶
Bases:
holoscan.core.Operator
This operator reads a nifti image, extracts the numpy array and forwards it to the next operator
- Named input:
image_path: Path to the image file, optional. Use it to override the input path set on the object.
- Named output:
image: A Numpy array object. Downstream receiver optional.
Creates an instance with the file path to load image from.
- Parameters
fragment (Fragment) – An instance of the Application class which is derived from Fragment.
input_path (Path) – The file Path to read from, overridden by valid named input on compute.
Methods
__init__
(fragment, *args, input_path, **kwargs)Creates an instance with the file path to load image from.
add_arg
(*args, **kwargs)Overloaded function.
compute
(op_input, op_output, context)Performs computation with the provided context.
convert_and_save
(nii_path)reads the nifti image and returns a numpy image array
Default implementation of initialize
setup
(spec)Default implementation of setup method.
start
()Default implementation of start
stop
()Default implementation of stop

- property name¶
- __init__(fragment, *args, input_path, **kwargs)[source]¶
Creates an instance with the file path to load image from.
- Parameters
fragment (Fragment) – An instance of the Application class which is derived from Fragment.
input_path (Path) – The file Path to read from, overridden by valid named input on compute.
- add_arg(*args, **kwargs)¶
Overloaded function.
add_arg(self: holoscan.core._core.Operator, arg: holoscan.core._core.Arg) -> None
Add an argument to the component.
add_arg(self: holoscan.core._core.Operator, arg: holoscan.core._core.ArgList) -> None
Add a list of arguments to the component.
add_arg(self: holoscan.core._core.Operator, **kwargs) -> None
Add arguments to the component via Python kwargs.
add_arg(self: holoscan.core._core.Operator, arg: holoscan.core._core.Condition) -> None
add_arg(self: holoscan.core._core.Operator, arg: holoscan.core._core.Resource) -> None
Add a condition or resource to the Operator.
This can be used to add a condition or resource to an operator after it has already been constructed.
- argholoscan.core.Condition or holoscan.core.Resource
The condition or resource to add.
- property args¶
The list of arguments associated with the component.
arglist : holoscan.core.ArgList
- property conditions¶
Conditions associated with the operator.
- property description¶
YAML formatted string describing the operator.
- property fragment¶
The fragment (
holoscan.core.Fragment
) that the operator belongs to.
- property id¶
The identifier of the component.
The identifier is initially set to
-1
, and will become a valid value when the component is initialized.With the default executor (holoscan.gxf.GXFExecutor), the identifier is set to the GXF component ID.
id : int
- initialize()¶
Default implementation of initialize
- property name¶
The name of the operator.
- property operator_type¶
The operator type.
holoscan.core.Operator.OperatorType enum representing the type of the operator. The two types currently implemented are native and GXF.
- property resources¶
Resources associated with the operator.
- property spec¶
The operator spec (
holoscan.core.OperatorSpec
) associated with the operator.
- start()¶
Default implementation of start
- stop()¶
Default implementation of stop
