A problem with incompatibility between env.reset() methods #74

I configured the code environment as readme.md shows. And I run
python main.py --split val --eval 1 --train_global 0 --train_local 0 --train_slam 0 --load_global pretrained_models/model_best.global --load_local pretrained_models/model_best.local --load_slam pretrained_models/model_best.slam .
But I got the following error.

Traceback (most recent call last):
File "main.py", line 789, in
main()
File "main.py", line 136, in main
obs, infos = envs.reset()
File "/home/csy/source_code/Neural-SLAM/env/init.py", line 27, in reset
obs, infos = self.venv.reset()
ValueError: not enough values to unpack (expected 2, got 1)

It is due to the inconsistency between the call and definition of reset method. The definition in file env/habitat/habitat_api/habitat/core/vector_env.py Line 249 is as follows
`
def reset(self):

      Returns:
          list of outputs from the reset method of envs.
      self._is_waiting = True
      for write_fn in self._connection_write_fns:
          write_fn((RESET_COMMAND, None))
      results = []
      for read_fn in self._connection_read_fns:
          results.append(read_fn())
      self._is_waiting = False
      return results

`
I copied the repo habitat-api to the directory manually. (I am not sure if the error is related to this.)
Can anyone give me some help? Thanks !
