QUESTION
Can anyone tell me if one can directly select the DNN AI core for neural network evaluation on HoloLens 2.
I have read about the HPU, which includes and DNN AI core in the GitHub repo here. But in the doc for the devices that can be used only CPU and GPU are listed.
...ANSWER
Answered 2021-Jun-07 at 17:27Currently Windows AI only supports inference on CPUs or GPUs.
Unfortunately there isn't a way to perform inference on the HoloLens2 HPU DNN AI Core at the moment.
QUESTION
I am trying to pass an object of key-value pairs with the value being an array of strings from a Child component to a Parent's state. These values will come from UI-Kitten's multi-select component and it'll be passed as an object to the Parent.
I understand how passing of data works between parent and child components and the usage of useEffect
in a component for componentDidMount
or any conditional fires of an effect. But this case is rather complex.
I could possibly dump the entire Child component into the Parent as I have tried replicating something similar and it works i.e. I get the object of key-value pairs updated whenever user selects/deselects an option from the multi-select. Hoping that I could take the Child-Parent so the Parent wouldn't clutter up as the Child component is pretty long.
I hope I could get some help with it. Thank you!
Parent Component (the state, technologyExperience, is not updating):
...ANSWER
Answered 2021-May-27 at 09:32It seems the bulk of your issue here is a misunderstanding of React hook dependencies. You are using the state updater function as the dependency, but these are stable references, i.e. they are the same from render to render, so if included in a hook's dependency array they won't trigger the hook callback.
Note
React guarantees that
setState
function identity is stable and won’t change on re-renders. This is why it’s safe to omit from theuseEffect
oruseCallback
dependency list.
You will see the useEffect
callback called once on the initial render, but since the dependencies are stable they are never updated and will never trigger the effect callback again later.
Additional Issues
Within the InputBackgroundSelect
component the displayGameDev, displayWebDev, displaymobileDev, displayDb, displayMl, getSelections
variables are dependencies for the useEffect
for the getSelections
callback, but they are declared in the function body of the component. This means they are redeclared each render cycle, thus triggering some render looping.
Fix the useEffect
dependencies in both the parent and child component. Hook dependencies are basically anything that is referenced within the callback that make change from render to render.

Answered 2021-Apr-14 at 21:46I am currently doing this (code below) but it doesn't seem to work as it returns an API exception error and the program crashes.
The reason it crashes is due to no handling of exception within the code. Your approach also seems flawed. Your try statements can be split into something like this (credit)
