Hi,  
I am currently trying to step through the tutorial posted at [https://tutorials.pumas.ai/html/introduction/introduction.html](https://tutorials.pumas.ai/html/introduction/introduction.html)  
(side note, a lot of the documentation links are not being found because they have an exta /dev in the URL)  
I am using my own data, so I unfortunately can’t post too much detail on that.

The first thing I noticed it that my gof plots do not have local regression lines (otherwise they work)  
Then, when running the VPC, I get an error **LinearAlgebra.LAPACKException(2)**

I appreciate any help in making things work.

Running Pumas v1.0.2, PumasPlots v0.1.3

Thanks,  
Sven

Hi Sven

> The first thing I noticed it that my gof plots do not have local regression lines (otherwise they work)

Could you please show us the full output of `] st`? It might be an issue with one of the plotting packages so  
I’d like to know exactly which version you are using.

> Then, when running the VPC, I get an error **LinearAlgebra.LAPACKException(2)**

Please see the _tip_ box at [https://docs.pumas.ai/analysis/vpc/#Visual-Predictive-Check-(VPC)](https://docs.pumas.ai/analysis/vpc/#Visual-Predictive-Check-(VPC)). We are working on intercepting the exception to provide a better error message.

Thanks for letting us know. We made a lot of changes to the websites last week and indeed it looks like it broke some links. We are working on fixing it.

Thank you for the quick reply. Increasing bandwidth as suggested fixed the VPC.

I forgot to ask, what is the output of `versioninfo()`?

I think that some of the installed packages are causing other packages not to be up-to-date. It’s fixed in a the upcoming binary release but I assume it will be easier for you to simply adjust the installed packages.

In that case, could you please try to `] rm` the two packages `StatPlots` (notice that it’s not `StatsPlots`) and `Metalhead` and then `] up`, then restart your Julia session, and report back to us if the local regression line appears in the plot.

Thank you Andreas, your suggested approach fixed the problem.
