- 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
keyof the requested property.
- Supported backends
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 via
fn.readers.file()returns full path of the file, from which the tensor comes from.
"layout": Returned type: byte-array
Data layout in the given Tensor.
bytes_per_sample_hint (int or list of int, optional, default = ) –
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) –
If not provided, it will be populated based on the global seed of the pipeline.
