Summary
I'm trying to run the simple custom environment example. It will try to start but while it saying "Connecting to server" on Luanti startup I continuously get the following error.
==> Creating Minetest run directory: ./minetest-run-e8021cb4-c9b7-44b3-b84b-fbd4be86a5dd
Traceback (most recent call last):
File "/home/zss/Intrinsic/Testing/test.py", line 18, in

^^^^^^^^^^^

ConnectionError: Failed to receive from MT. Connection closed by peer: is MT down?
I believe I've followed all the proper steps and it does try to run. It works fine when manually starting a world with
./bin/luanti Any help would be greatly appreciated thank you so much in advance.
Steps to reproduce
import time
import os
from craftium import CraftiumEnv
env = CraftiumEnv(
env_dir="/home/zss/Intrinsic/Environment/small-room",
render_mode="human",
obs_width=512,
obs_height=512,
minetest_dir="/home/zss/Intrinsic/craftium"
)
print(env)
iters = 1000
observation, info = env.reset()
ep_ret = 0
start = time.time()
for i in range(iters):
action = dict() # empty action (do nothing)
observation, reward, terminated, truncated, _info = env.step(action)
ep_ret += reward
print(i, reward, terminated, truncated, ep_ret)
if terminated or truncated:
observation, info = env.reset()
ep_ret = 0
end = time.time()
print(f"** {iters} frames in {end-start}s => {(end-start)/iters} per frame")
env.close() This is my code snippet and I followed the Creating custom environments section of the docs. It fails at the Using the custom environment section.
