error when python main.py -n1 --auto_gpu_config 0 --split val about neural-slam HOT 7 CLOSED

This error is some bug in python 3.6, if you update to python 3.7 it should be fixed without any change in code.

It's probably not the most ideal solution, but I changed the import statements to from import statements. i.e.:

# import env.habitat.utils.pose as pu
from env.habitat.utils import pose as pu

Also I realize that my error may be different from the version issue in the original post.

Hi,
This is likely because you are using a different version of habitat-sim and/or habitat-api. Can you confirm if you are checking out the commits mentioned in the README.md for habitat-sim and habitat-api?

I got stuck at the same place. However the traceback stops at /content/Neural-SLAM/env/habitat/exploration_env.py. I verified I was on the specified branches in habitat-sim and habitat-api. I'm on a Mac.

Following is my traceback:

Traceback (most recent call last):

Hello all @devendrachaplot , @Zjhzzzzz , @shahhaard47 . I was facing the same error ImportError: cannot import name 'register_move_fn' however my habitat-sim and habitat-api setup was running fine.
As suggested I installed everything in the new virtual env with python3.7. Now, I am getting following error

(ANS1) hemnani1@BOSS8-OS:~/DIR/habitat-api$ python examples/example.py
Traceback (most recent call last):
File "examples/example.py", line 7, in
import habitat
File "/DATA/hemnani1/DIR/habitat-api/habitat/init.py", line 7, in

from yacs.config import CfgNode as Config
File "/DATA/hemnani1/.local/lib/python3.7/site-packages/yacs/config.py", line 30, in
import yaml
ModuleNotFoundError: No module named 'yaml'

Now, even the example.py file of habitat is not working .
How did you all resolve this error? and what things you took care while installation . Please, suggest me some solution.

After trying in python 3.7:
I am getting following error:

Can someone help me to resolve this?
