As title. I have the following stack track when I try to import nengo_loihi through SLURM on the Intel superhost:

Welcome again @kshivvy to our community! The most recent stable version of Nengo Loihi doesn’t support NxSDK 1.0.0, rather 0.9.0 . More information here.

We have a branch that supports NxSDK 1.0.0.

I am having the same issue with the nxsdk.graph.nxboard module… Where you able to find the solution?
