Hi all,<\/p>\n
Last week, I was running a python script remotely through Lumerical’s Interop Server. This week, we updated the workstation (Ubuntu 22.04) that runs the server and now the exact same script gives the following error:<\/p>\n
1 remoteArgs={ \"hostname\": \"127.0.0.1\", \"port\": 8989}<\/span>
----> 2 fdtd = lumapi.FDTD(hide=True, remoteArgs=remoteArgs)<\/span>
