Seems your artiq_dashboard_{server}_{port}.pyon file is corrupted. Any idea how this happened? Try deleting it.

@dgy I've been getting this error occasionally too. I fixed it by deleting the ...dashboard... file at C:\Users<username>\AppData\Local\m-labs\artiq\5

Did you try this kind of folder?

Hello, I also have problem to find the artiq_dashboard_{server}_{port}.pyon file. I've searched the hard disk and I have searched inside the envs artiq folder. Can you please help locate it? Thanks

Edit: I really can't find it..

Vanimiaou

sb10q I see it now, there is a dashboard file not with the same name artiq_dashboard_{server}_{port}.pyon but I deleted it. Thanks for helping to find the cache.
