Hello I got an error message when run visitation and recreation. The message is shown below (log file is attached):

"05/27/2025 00:53:54 taskgraph.Task ERROR Something went wrong when adding task photo-user-day-calculation (1), terminating taskgraph.
Traceback (most recent call last):

Anyone have any idea to fix this problem. I run this model for province in Thailand

Hi @satha13 , thank you for reporting this error. The best thing to do if you can is update to the latest version of invest: InVEST Downloads, User Guides, and Data Sources | The Natural Capital Project

There were significant updates to the recreation model recently:

  • Added a database of geotagged tweets to support calculating twitter-user-days (TUD) as proxy for visitation rates. The model now calculates photo-user-days (PUD) and TUD and uses their average as the response variable in the regression model. Please refer to the User’s Guide for more details on the regression model.
  • Output data were updated to support the new TUD results, and vector outputs are now in GeoPackage format instead of ESRI Shapefile.
  • Regression coefficients are still listed in a summary text file, and are now also included in a tabular output: “regression_coefficients.csv”.

Hi @dave Thank you for your advise. I have updated to the latest version (3.15.1) and recreation model has worked smoothly.
