ce() missing 2 required positional arguments: 'Aell' and 'phi0'
Hi,
I have noticed that sometimes EBAI fails with TypeError: ce() missing 2 required positional arguments: 'Aell' and 'phi0' error. The working example can be found in the attachment, and the full error log is provided below:
2G model C failed with error: Residuals are not finite in the initial point.
2G model CE failed with error: Residuals are not finite in the initial point.
2G model CG failed with error: Residuals are not finite in the initial point.
2G model CGE failed with error: Residuals are not finite in the initial point.
2G model CG12 failed with error: Residuals are not finite in the initial point.
2G model CG12E1 failed with error: Residuals are not finite in the initial point.
2G model CG12E2 failed with error: Residuals are not finite in the initial point.

Does the error go away if you disable phase-binning in the solver options? See also https://github.com/phoebe-project/phoebe2/discussions/829 and https://github.com/phoebe-project/phoebe2/discussions/743.
This seems to be happening more and more though, so we'll try to bump its priority up and try to fix it in an upcoming bugfix. (Changing the title just so that it is a little more discoverable since this does occur for other solvers as well).
Disabling phase_bin does help, though I thought to emphasize this error knowing that it happened before and possibly has not been fully resolved. Thanks though!
Yep - still definitely needs to be fixed (or at least raising an error suggesting disabling phase-binning), so good to have this filed as an actual issue. Thanks!
