Crash when trying to load world

[LordMZTE]

my code:

world_folder = r"2b2t_org"
world = World(world_folder)

this will result in this exception:

Traceback (most recent call last):
  File "B:/Dev/Minecraft Sign Searcher/signsearcher.py", line 23, in <module>
    world = World(world_folder)
  File "B:\Dev\Minecraft Sign Searcher\minecrafty\world.py", line 21, in __init__
    self.regions = Regions(regions_folder)
  File "B:\Dev\Minecraft Sign Searcher\minecrafty\region.py", line 26, in __init__
    self[x, z] = Region(region_file)
  File "B:\Dev\Minecraft Sign Searcher\minecrafty\region.py", line 69, in __init__
    self[x, z] = Chunk(self._buffer)
  File "B:\Dev\Minecraft Sign Searcher\minecrafty\chunk.py", line 22, in __init__
    self._buffer = io.BytesIO(zlib.decompress(self._buffer.read(size)))
MemoryError
