Dear INLA-community


I am trying to fit a spatio-temporal LGCP thin model using inlabru (code and data provided below). I am encountering a few issues : the model fitting does not finish or I get the error message shown below. I have tried changing the mesh size and the study period, but it does not work any better. Do you have any ideas on how to fix this?

Kind regards,

Camille Mottier

Please run a basic inla test to verify that your INLA installation is working at all.
For an example of a basic test, see for example here:

Also provide your package versions, with sessionInfo() and upgrade if you don't have the latest versions of INLA and inlabru (25.12.16 and >= 2.13.0 respectively).

Thank you for your reply.

My INLA installation works correctly, and I think I have the same issues after upgrading INLA to the latest version. 

Here is my package versions :

If at all possible, upgrade to a recent R version (4.5.2) as recent inla are only built for that.

Can u share data and code so I can rerun here? Alternatively, run with keep=T and share the inla.model directory
