Can you reproduce this and suggest a solution? Best regards, Christian

Can you please check in the results folder if gamboostNB_total_count_site_name.rda is generated?

[schmidtchristi]

Thank you for the answer. No, the file is not generated.

[NandhiniS08]

Thanks for your reply.

• Since the model object did not generate, there is an error when we try to access the metric variable res_gamboostNB.
• We can check it together in a debug session. Please let me know when it's better for you tomorrow.
• May I ask if you are executing it in docker or Rstudio? Debugging would be easier if it's in R.

Had a debug session on 14.04.2023. Identified the issue and pushed a new image for projectathon6-miracum1-step2-gottingen-debug . to run the 6_modeling3_gamboost.R.
