get_xml() -> ResourceWarning: Enable tracemalloc to get the object allocation traceback

System Info

Robosuite version, Ubuntu 24.04

Information

I am receiving this warning from get_xml() in robosuite/utils/bindin_utils.py whenever get_state() is called

ResourceWarning: Enable tracemalloc to get the object allocation traceback
/home/bho36/Documents/code/FILM/./robosuite/robosuite/utils/binding_utils.py:506: ResourceWarning: unclosed file <_io.TextIOWrapper name='/tmp/tmpt8nu028r/model.xml' mode='r' encoding='UTF-8'>
  return open(filename).read()

My solution was to modify the code from this

    def get_xml(self):
        with TemporaryDirectory() as td:
            filename = os.path.join(td, "model.xml")
            ret = mujoco.mj_saveLastXML(filename.encode(), self._model)
            return open(filename).read()

to this.

    def get_xml(self):
        with TemporaryDirectory() as td:
            filename = os.path.join(td, "model.xml")
            ret = mujoco.mj_saveLastXML(filename.encode(), self._model)
            with open(filename) as f:
                return f.read()
