nvidia.dali.fn.
get_property
(*inputs, **kwargs)¶ Returns a property of the tensor passed as an input.
The type of the output will depend on the
key
of the requested property.- Supported backends
‘cpu’
‘gpu’
- Parameters
input (TensorList) – Input to the operator.
- Keyword Arguments
key (str) –
Specifies, which property is requested.
The following properties are supported:
"source_info"
: Returned type: byte-array.String-like byte array, which contains information about the origin of the sample. Fox example,
fn.get_property()
called on tensor loaded viafn.readers.file()
returns full path of the file, from which the tensor comes from.
"layout"
: Returned type: byte-arrayData layout in the given Tensor.
bytes_per_sample_hint (int or list of int, optional, default = [0]) –
Output size hint, in bytes per sample.
If specified, the operator’s outputs residing in GPU or page-locked host memory will be preallocated to accommodate a batch of samples of this size.
preserve (bool, optional, default = False) – Prevents the operator from being removed from the graph even if its outputs are not used.
seed (int, optional, default = -1) –
Random seed.
If not provided, it will be populated based on the global seed of the pipeline.
