2 years ago Using conda with python 3.8, this nengo-loihi branch and nxsdk 1.0.0, the gui will not work when using the nxsdk flag. I'm running on a cloud service I ssh into. After typing in the following command:
SLURM=1 nengo --port 8080 --no-browser --auto-shutdown 0 --backend nengo_loihiI was greeted by the following error in the gui window:

A notebook that I created based on the tutorial available here is running just fine however, so it seems that only the gui suffers from this problem. Furthermore using the following command will work just fine as well:
SLURM=1 nengo --port 8080 --no-browser --auto-shutdown 0Thus I'm fairly sure that the error has to do with nengo-loihi.

2 years ago Closing this as it's tightly coupled with other work in #318 which also includes these commits.
@adiehl96 I made a new issue, #319, to investigate the NengoGUI issue.
For anyone who wants to apply this in the meantime:
pip install git+https://github.com/nengo/nengo-loihi.git@nxsdk100
