No belief list file: facet-test-00.belief about task-models HOT 3 CLOSED

OK. Sorry to come back so late on it. Actually this is a bug in the solver pomdp-solve that is used by the code. It has been fixed on this repository: github.com/cmansley/pomdp-solve. I forgot that I had switched to this version on the code so that's why you were having the issue.

The solution is to compile pomdp-solve from this version. I'll update the README accordingly. Sorry for the wrong documentation and thanks again for the notice!

Hi @murphywonsick. Thanks for reporting the issue. It seems that this is caused by the pomdp-solve executable. The facet-test-00.belief file is apperently something that it needs to generate internally. Could you tell use on which platform you're running the code and try to run pomdp-solve manually against the attached file?

You should be able to do it the following way, from the directory were you'll have placed the attached tosolve.pomdp:

/usr/local/bin/pomdp-solve -horizon 500 -method grid -fg_type simplex -o tosolve -pomdp tosolve.pomdp

If it still does not work, can you run the following instead?

/usr/local/bin/pomdp-solve -horizon 10 -o tosolve -pomdp tosolve.pomdp

Note: I could only attach the file as .TXT so you'll need to rename it as a .pomdp.

I'm on Ubuntu 14.04.
The first suggestion did not work, it throws the exact same error as before. The second suggestion finds a solution though and provides the .alpha and .pg files.

From what I found, the facet-test-00.belief is read from finite-grid.c in the pomdp-solve-5.4 code. However, I have been unable to figure out yet how/when that file is generated so I was hoping that I was just missing something on my end. I tried to self generate the file by creating an empty file with the proper name, but that only replaces the "does not exist" error with a "file format incorrect".
