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?
