I was looking at the roadmap and just getting up to speed with Mycroft.
Being a noob my assumptions are relatively blind but it would seem generally there is a shift to neural network technologies for key Mycroft components.
I was just interested if anyone had tried tensorflow with the Pi now its has an alternative to GPU based offering.
" Identify hardware targets and create recommendations list
As rapidly evolving technologies, the requirements to run full STT and TTS services is a moving target. But recognizing the demands helps shape the system, too, so is valuable to look at early. Examine options such as:
- Hosted STT/TTS hardware recommendations and limitations, e.g. “1 GTX 1080 can handle X Mycroft units” or “1 FPGA (brand and type need to be specced) can handle Y Mycroft units”
- Look at lower-power options such as STT/TTS passthru with account randomization"
It was just curiosity but I did wonder “1 Coral Edge TPU can handle X Mycroft units” with the Pi4 being able to steam to multiple dumb WiFi speaker/mics.
They are still pretty pricey in comparison to the cost of a Pi4 but $75 gives 4 TOPs and being USB the Pi4 might be able to handle x2.
But my thoughts where along the lines of could a Pi4 & TPU handle 4 or more Mycroft units as its likely they will drop in cost and not far out of line of multiple Google/Amazon offerings in overall price.
That so much is in the neural network domain that even parsing text semantics from webpages could also be accelerated greatly.
Like this article as a semantic aware webcrawler would be pretty damn awesome https://medium.com/teleporthq-io/understanding-the-web-parsing-web-pages-semantically-805ef857854d
With the roadmap and current neural net libs chosen as I noob I am head scratching to why not tensorcore-light for all?
Also has anyone played with GPU/TPU acceleration? As just extremely curious how much load can the TPU handle and what resultant load is on the Pi4.
You can still run CPU based tensorcore-light but at an instant add a TPU and gain much accelaration…
There are quite a few now on the market but the Coral edge just seems to be getting the most Pi focus.
