AttributeError: module 'env' has no attribute 'habitat'

[XYZ-99]

I installed the environment according to README.md:

conda create -n Neural-SLAM python=3.6;     # for creating a conda environment
conda activate Neural-SLAM;                 # for conda
git clone https://github.com/facebookresearch/habitat-sim.git;
cd habitat-sim; git checkout 9575dcd45fe6f55d2a44043833af08972a7895a9;
pip install -r requirements.txt;

git clone https://github.com/facebookresearch/habitat-api.git;
cd habitat-api; git checkout b5f2b00a25627ecb52b43b13ea96b05998d9a121;

python main.py -n1 --auto_gpu_config 0 --split val;

An error then occurred:

Are there any extra commands that I have missed?

I believe this is some bug in python 3.6 as I described in this issue here: https://github.com/devendrachaplot/Neural-SLAM/issues/1#issuecomment-616630502

If you update the python version to 3.7, this issue should be resolved.

@devendrachaplot if I update the python version to 3.7 the habitat-sim version you advertise is not compatible. I am using release 0.1.4. Would it be possible to use a later habitat release with your code?

habitat-sim=0.1.4 -> python[version='>=3.6,<3.7.0a0']

[umerhasan17]

@devendrachaplot Unfortunately, habitat-sim=0.1.5 also requires python 3.6

Unfortunately, I cannot see how to use python 3.7 as a workaround since the datasets require python 3.6. How did you implement this with the existing bugs in python 3.6 previously?
