I have to say that I consider the whole process of developing with Xcode deeply annoying. I recently had a problem where it claimed that I needed to set a development team for signing even though I already had. After spending a lot of time deleting, recreating projects etc etc, I realized that clearly Xcode was keeping some information elsewhere that was causing the problem.
Turns out that it caches some information in:
Each project has a folder here. I deleted any folders that had the same name as my project and that fixed the problem. Ugh. And don’t get me started on bitcode…
The latest iPads and iPhones have some pretty serious edge neural network capabilities that are a natural fit with ARKit and Unity. AR and Unity go together quite nicely as AR provides an excellent way of communicating back to the user the results of intelligently processing sensor data from the user, other users and static (infrastructure) sensors in a space. The screen capture above was obtained from code largely based on this repo which integrates Core ML models with Unity. In this case, Inceptionv3 was used. While it isn’t perfect, it does ably demonstrate that this can be done. Getting the plugin to work was quite straightforward – you just have to include the mlmodel file in XCode via the Files -> Add Files menu option rather than dragging the file into the project. The development cycle is pretty annoying as the plugin won’t run in the Unity Editor and compile (on my old Mac Mini) is painfully slow but I guess a decent Mac would do a better job.
This all brings up the point that there seem to be different perceptions of what the edge actually is. rt-ai can be perceived as a local aggregation and compute facility for inference-capable or conventional mobile and infrastructure devices (such as security cameras) – basically an edge compute facility supporting edge devices. A particular advantage of edge compute is that it is possible to integrate legacy devices (such as dumb cameras) into an AI-enhanced system by utilizing edge compute inference capabilities. In a sense, edge compute is a local mini-cloud, providing high capacity compute and inference a short distance in time away from sensors and actuators. This minimizes backhaul and latency, not to mention securing data in the local area rather than dispersing it in a cloud. It can also be very cost-effective when compared to the costs of running multiple cloud CPU instances 24/7.
Given the latest developments in tablets and smart phones, it is essential that rt-ai Edge be able to incorporate inference-capable devices into its stream processing networks. Inference-capable, per user devices make scaling very straightforward as capability increases in direct proportion to the number of users of an edge system. The normal rt-ai Edge deployment system can’t be used with mobile devices which requires (at the very least) framework apps to make use of AI models within the devices themselves. However, with that proviso, it is certainly possible to incorporate smart edge devices into edge networks with rt-ai Edge.
