Hello,
I'm currently studying localized latent factor models and I'm trying to run the code.
I prepared the data according to the manual and tried to run the multicontext function, but an error occurred.

This is my setting and code.

setting = data.frame(
  name = 'uvw3-F',
  has.u = FALSE,
  has.gamma = FALSE,
  nFactors = 33,
  nLocalFactors = 3,
  is.logistic = FALSE
)

ans = run.multicontext(
              data.train = data.train, data.test=data.test,
              setting = setting,
              nSamples = 200,
              nBurnIn = 30,
              nIter = 30,
              out.dir="multi_results/");

max(obs$edge.context) is 11. So, I set the nLocalFactors = 3 and nFactors = 3*11 = 33.
But, The following error occurs

Error in run.multicontext(data.train = data.train, data.test = data.test,  : 
  Please check input parameter 'setting' when calling function run.multicontext: setting$nFactors must = setting$nLocalFactors * max(obs$edge.context).

Am I misunderstanding the setting? I'd appreciate it if you could tell me what the problem is.

Thank you for providing good research and code.

Hi,
Follow the tutorial and I got this error:
Error in .Call("sum_margin", out, A, as.integer(nrow(A)), as.integer(ncol(A)), :
载入表里没有"C"字符名"sum_margin"

I have try my best to find the solution, but failed. Please give me some help, thanks. I run the code on my Mac with R version 3.3.2 .

The tutorial-BST.R gives the following error:

I am using R version 3.0.1 (2013-05-16) -- "Good Sport" and the C, FORTRAN code compiles without any warning message.
What are the possible reasons for this error? Thanks.

Hi,

Following is the output of my make:

Should there be an arms.c somewhere?

Thanks!

Hi,
Follow the tutorial and I got this issue:

I finally got it compiled (thanks to the solutions provided by others), but when I ran it, I got this error:

Error in dyn.load(sprintf("%slib/c_funcs.so", code.dir)) :

I am using R version 3.2.4 on Mac OSX. Wonder if anyone has seen this?

I want to translate your book into Chinese, and I hope I can get your permission.
