4 years ago Hi @pilgrimygy sorry about the error - this is frustrating. Currently LaserTag uses latex to render images, and it appears that there is a problem with the latex rendering.
You should be able to run simulations fine, but rendering may not work.
The best way to fix it would be to replace the latex rendering with Compose.jl rendering. It should look like this: https://github.com/zsunberg/DMUStudent.jl/blob/master/src/HW6.jl#L199
Unfortunately I won't have time to do this for a bit. Do you want to take a shot at it?
When I run the code： using LaserTag using POMDPGifs using QMDP using Random using ParticleFilters
rng = MersenneTwister(7)
m = gen_lasertag(rng=rng, robot_position_known=true) policy = solve(QMDPSolver(verbose=true), m) filter = SIRParticleFilter(m, 10000, rng=rng)
@show makegif(m, policy, filter, filename="out.gif", rng=rng)
I encountered this problem, and I can't solve it. Could you give me a hand?
