printing output of `EpsGreedyPolicy(mdp, LinearDecaySchedule)` fails
if the output is muted with ; everything works as expected, but if not then error is thrown.
MWE
julia> using POMDPs, POMDPModels, POMDPTools
julia> mdp = SimpleGridWorld();
julia> exploration = EpsGreedyPolicy(mdp, 0.9); # works
julia> exploration = EpsGreedyPolicy(mdp, LinearDecaySchedule(start=1.0, stop=0.01, steps=10000/2)); # works
julia> exploration = EpsGreedyPolicy(mdp, LinearDecaySchedule(start=1.0, stop=0.01, steps=10000/2)) # problem with printing
