error "Probabilities sum up to 0. It should sum up to 1" #7

Closed rguptatx closed 7 years ago

rguptatx commented 8 years ago

I extended the GridWorld example with observations. I get the error: Probabilities sum up to 0. It should sum up to 1

here is a log: WARNING model.pomdpx:Line 32: In Belief Function Tables state0 In instance null Probabilities sum up to 0. It should sum up to 1 ERROR: LoadError: failed process: Process(/.julia/v0.4/SARSOP/deps/appl-0.96/src/pomdpsol model.pomdpx --output out.policy, ProcessExited(255)) [255] in run at ./process.jl:531 in solve at /.julia/v0.4/SARSOP/src/solver.jl:100 in solve at /.julia/v0.4/SARSOP/src/solver.jl:98 in include at ./boot.jl:261 in include_from_node1 at ./loading.jl:320 in process_options at ./client.jl:280 in _start at ./client.jl:378 while loading pgridworld.jl, in expression starting on line 498

Any pointers to what I am missing in code, or how to go about figuring out source of error would be greatly appreciated.

Can you post the model.pomdpx that gets generated? That might give us a hint.

model.pomdpx attached model.pomdpx.txt

It appears that your initial belief state assigns zero probability to all states. This distribution should sum to 1.
