Source: [https://docs.qualcomm.com/doc/80-70023-50/topic/qtimlsnpe.html](https://docs.qualcomm.com/doc/80-70023-50/topic/qtimlsnpe.html)
The qtimlsnpe plugin shows the Qualcomm^®^ Neural Processing SDK
capabilities (load and run the models).
It accepts a tensor prepared by preprocessing elements such as qtimlvconverter and
produces an output tensor that's parsed by postprocessing plugins such as
qtimlvclassification, qtimlvdetection, qtimlvsegmentation, and qtimlvpose.
This plugin does the following:
- Accepts a tensor prepared by the preprocessing elements such as
qtimlvconverter.
- Produces the output tensor that's parsed by the postprocessing plugins such as
qtimlvclassification, qtimlvdetection, qtimlvsegmentation, and qtimlvpose.
- Uses the Qualcomm Neural Processing SDK library.
- Uses the ION/DMA buffers assigned by the GstMLBufferPool custom buffer pool class
through IOCTL commands to the kernel.
The model and delegate usage is as follows:
- To use a model, provide the absolute path of the model through the model
property.
For some models, you may have to set the extra layers
property.
After it's loaded, the model file provides the input and output
capabilities:
- Number of tensors
- Dimensions
- Type
- If a delegate isn't specified, the plugin executes the model operations on the
CPU.
- To select a different delegate, set the delegate property accordingly. For more
information, see the [Table : Element properties of qtimlsnpe](https://docs.qualcomm.com/doc/80-70023-50/topic/qtimlsnpe.html#qtimlsnpe__table_ids_q34_myb).
