Problem Displaying Chains

[levis]

Hello,

Any time i try and run multiple chains in rstudio i get an error

“The process cannot access the file because it is being used by another process”

its not a problem with one chain. And its definitely not an issue of google drive/one drive which i made sure to unsync in case it was an intereference. I went and get ProcessExplorer and could not find any intereference

Using
R version 4.0
RStudio 1.3.959
Rstan 2.19.3
Windows 10

Thanks in advance!

I think it’s a bug in RStudio see here:

RStudio Viewer with rstan running in parrallel with RStudio 1.3

I just updated to R 4.0.0 and Rstudio 1.3.959, and also updated Rtools and rstan at the same time, and now am having the same issue reported here (cannot view progress on viewer). The model fitting is successful, and once it is done I can view the results in viewer, however when I try and refresh the Viewer window to see progress while it is running I get the “The process cannot access the file because it is being used by another process.” error message

Thank you! I guess I will wait for any updates or try going back to an older Rstudio version

Yeah, I’d go back to RStudio 1.2.5042 and subscribe to the thread below to find out when the issue is fixed.

It is fixed now with Rstudio Version 1.3.1056
