Hi Paul,

This is an issue introduced by recent nengo changes that we haven’t yet addressed in the master branch of nengo-loihi. In the mean time, you can use the nengo-dev branch of nengo-loihi if you’re working with NxSDK 0.8.5, the nxsdk087 branch if you’re working with NxSDK 0.8.7, and the nxsdk090 branch if you’re working with NxSDK 0.9. Note that we’ll be dropping support for NxSDK 0.8.5 shortly.
