Cannot locate artifact 'libknet8' in KNet

Hello,

I have downloaded Knet from GitHub - denizyuret/Knet.jl: Koç University deep learning framework. (but I have the same problem when I download Knet with Pkg.add(“Knet”)) to a Nvidia Jetson Nano (as it is an inexpensive method to finalise a Monte Carlo simulation using a GPU to be later run on a supercomputer)

When using Knet I have an error and it appears libknet8 cannot be found. I have googled a bit and found some posts related to Knet and libknet8 but I don’t understand what can be done to overcome this problem. Any suggestion to get around this would be very useful and very much appreciated.

I post the error and some package and system info below.

Thank you for any help,

Giovanni
