Describe issue

Currently I am using version 3.10.6001 (dev) of Robyn. When I use 2 to 4 variables, the model runs successfully. However, when I run the model with 12 to 14 variables, the following error occurs: "Error in png_dev(..., res = dpi, units = "in") "err_trace": "Traceback (most recent call last):\n File "/app/src/robyn/python/robyn_train.py" Can someone help me with this, Is this the problem of robyn ?

Environment & Robyn version

Make sure you're using the latest Robyn version before you post an issue.

• R version (3.10.6001 (dev))

Hi @amanrai2508 , How are you using Robyn, is it API for Python? Is robyn_train.py a program you created?
Also, please share the following

• OS info
• Source code where the error occurred
• Full text of the error message

Thanks,

Yes, It is an API for python on top of R code ( It is working in production PRD: 3.10.3 (from their official cran release))

OS : Macos 14.4.1

Thanks, Can you share the code where the error is happening? Also can you try R version Robyn (not API) to test whether the same error happen or not?
