When I set config\_do\_restart=true, this error was solved. But then when I ran it, I encountered a new error as follows. It looks like the program can not find the hdf library, but I did not encounter such a bug in the Hofx tutorial. I use [obs2ioda.x](https://forums.jcsda.org/t/observation-data-for-simulating-observations/232) to get my observation data. Is there a problem with the observations I converted?
