error when python main.py -n1 --auto_gpu_config 0 --split val

[mmdzzh]

I use googlecolab
I obey all the step before and I get an error when I try to test

python main.py -n1 --auto_gpu_config 0 --split val
I get this error

Traceback (most recent call last):
File "main.py", line 15, in

ImportError: cannot import name 'register_move_fn'

I find there is no register_move_fn in habitat-sim/habitat_sim/agent/controls
Troubled with this, can u help me?
thank you!

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):
  File "main.py", line 15, in <module>
    from env import make_vec_envs
  File "/Users/haardshah/development/gatech/DL_CS7643/habitat/habitat-submission/neural-SLAM/env/__init__.py", line 3, in <module>

    import env.habitat.utils.pose as pu
AttributeError: module 'env' has no attribute 'habitat'

[shahhaard47]

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.

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.

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?
