| [statet-users] Problems with mlr3 |
Hi, The package mlr3 is based on R6 objects in R. This is just a preliminary question so I am not including a full reproducible scenario yet. I am having trouble doing anything of any size in mlr3 under statet without getting a large number of messages like those appended below. These are then repeated every time I run enter any R line. While I totally realize the messages are from within mlr3, and in terms of mlr3 internals, I thought I would at least ask here if this rang any bells. My searches do find bugs involving somewhat similar messages in mlr3 in the past, they are supposed to be fixed. I am running the latest mlr3 installed today, Eclipse 2022.03 updated to 2022.06, the very latest Statet under Windows 11, and R 4.1.3. Error: The backend of Task 'Vol' has been removed. Set `store_backends` to `TRUE` during model fitting to conserve it. Error: The backend of Task 'Vol' has been removed. Set `store_backends` to `TRUE` during model fitting to conserve it. Eventually, after a lot of these messages, R exits suddenly. [INFO ] Jun 23, 2022, 1:34:28 AM - R stopped. Now, these problems do not occur at all with the same R code under plain 4.1.3 all alone. It is the exact same installation of R. I see the following in the error log: !ENTRY org.eclipse.statet.rj.client 4 0 2022-06-23 01:34:28.142 !MESSAGE Communication error detail.
