Some problem

[pilgrimygy]

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?

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?
