Hello,

Need some help please, with printing out the Q-matrix when using MDP and Tabular TD learning.

I have been able to formulate the MDP and the solver and solve the policy. The code is

```
mdp = TabularMDP(T, R, Discount_factor);
print("\nStep-1: MDP object created")
# use Q-Learning
exppolicy = EpsGreedyPolicy(mdp, 0.02)
q_learning_solver = QLearningSolver(exploration_policy=exppolicy,
n_episodes=1000,
max_episode_length=100,
learning_rate=0.5,
eval_every=10000,
n_eval_traj=20,
verbose=true);
print("\nStep-2: Solver working")
policy = solve(q_learning_solver, mdp)
print("\nStep-3: Policy solved \n")
```

When I run this in debug mode, I am able to see the value table

How do I print this to console? I tried using

`showpolicy(stdout,"text/plain", mdp, policy)`

But this shows the following error.

Exception has occurred: MethodError

MethodError: no method matching showpolicy(::Base.TTY, ::String, ::TabularMDP, ::ValuePolicy{TabularMDP, Matrix{Float64}, Int64})

Closest candidates are:

showpolicy(::IO, !Matched::MIME{Symbol(â€śtext/plainâ€ť)}, ::MDP, ::Policy; pre, kwargsâ€¦)

What would be the correct way to print the q-matrix to console? Thank you
