Problems getting SARSOP running #25

Closed jamgochiana closed 4 years ago

jamgochiana commented 6 years ago

Hi,

I'm having problems getting the SARSOP solver running on a custom POMDP. FIB and QMDP are both solving fine. My packages all seem up to date.

I'm getting the following out:

(Working) Generating a pomdpx file: model.pomdpx

(Error) could not spawn 'C:\...\.julia\v0.6\SARSOP\deps\appl\src\pomdpsol' model.pomdpx --output out.policy: no such file or directory (ENOENT)

Any solutions?

Thanks, Arec

Hi @jamgochiana , it looks like you are using windows and the SARSOP executable did not install directly. Does the file C:\...\.julia\v0.6\SARSOP\deps\appl\src\pomdpsol exist on your machine? What is the output of julia> Pkg.build("SARSOP")?

These issues may also be helpuful: https://github.com/JuliaPOMDP/SARSOP.jl/issues?utf8=%E2%9C%93&q=is%3Aissue+windows

Also, I'm assuming you are using Julia 0.6? I don't think SARSOP will work on 0.7/1.0 yet.

I'm getting the error:

LoadError: could not spawn unzip appl-0.96win.zip: no such file or directory (ENOENT) while loading C:...julia\v0.6\SARSOP\deps\build.jl, in expression starting on line 17

which is weird since there is a zip file with that name in the deps folder. And yes Im using Julia 0.6 on Windows

Thanks

I think "no such file or directory" is referring to unzip. Apparently your computer does not have the unzip program installed/accessible. You can look at deps\build.jl and do all those steps manually and the package should work after you have compiled SARSOP. (cd="change directory")

I don't know what the permanent solution is. Maybe use https://github.com/fhs/ZipFile.jl @MaximeBouton @mykelk do you know what the right way to do this in windows is?

I think the right way to do this is with https://github.com/JuliaPackaging/BinaryProvider.jl

This might be a fun first project for @jamgochiana ;-)

It seems to be working fine on windows now + we have CI with travis. Let's use #36 to discuss more about using BinaryBuilder
