Error Running Simple Space-Time Example

[Sylvanben]

Hi,

After recently updating MetricGraph and rSPDE I am getting an error when running the code from the simple space-time example: https://davidbolin.github.io/MetricGraph/articles/spacetime.html#inlabru-implementation

When running the code:

st_graph <- rspde.spacetime(mesh_space = graph, mesh_time = mesh_time, alpha = 1, beta = 1)

I get the following error:

Warning message: In value[[3L]](cond) : Error while loading the shared library or checking the symbol: unable to load shared object 'C:/Users/sbenaksas/AppData/Local/R/win-library/4.4/INLA/bin/windows/64bit/external/rSPDE/librSPDE.so': LoadLibrary failure: The specified module could not be found. . Please install the latest testing version of INLA. If the problem persists after installing the latest testing version of INLA, please open an issue at https://github.com/davidbolin/rSPDE/issues, requesting that this model be added to INLA.

Any help would be greatly appreciated,
Sylvan

Hi Sylvan, did you also install the latest testing version of INLA?

Hi Alexandre,

Yes I believe I have, I also updated RStudio yesterday.

`> packageVersion("INLA")
[1] ‘24.12.11’

packageVersion("rSPDE")
[1] ‘2.4.0.9000’
packageVersion("MetricGraph")
[1] ‘1.4.0.9000’`

Thanks

Yes, this should be the newest version indeed. Can you try something for me, please?

can you try to fit the model?

because this warning comes from trying to load the symbol (function) from the shared object, basically this space time model is a C function that inla will use, and this warnings appears if we try to “load” the function, and R was unable to load it.

we have tested in Linux and mac, but not in windows indeed. There is also one thing I needed to do, and I had not done yet, which is to try to load the function using the libraries from inla’s folder.

if you are able to fit, it means you can run, but R does not have the needed libraries loaded, to be able to load the function, to check that the function does exist.

if that is the case, I will try to fix this, and I would be very happy if you could test for us, that the warning will disappear.

if you cannot fit the model, then it is something else, and we will need to investigate further.

thanks.

Hi Alexandre,

Yes you are right, despite this message the model does seem to run. I am now running my own model to see what the outputs look like.

Many thanks,
Sylvan

Hi Sylvan,

Could install the newest devel version of rSPDE and try again to see if you still get these warnings?

I added INLA's libraries from windows as well in the path so hopefully it should remove the warning.

Best,
Alexandre

Hi Alexandre,

Yes I get no warning now after updating the package,

Cheers,
Sylvan

Great, Sylvan! Thank you very much for the feedback. Then, I believe this issue should be solved.
