ModuleNotFoundError: No module named 'habitat_sim._ext'

[ducha-aiki]

I have the same problem as described here
#48

1. python setup.py install
   Neither build.sh nor python setup.py install --headless help. Build is successfull.

2. Download habitat-test-scenes from provided link

3. python examples/example.py --scene /path/to/data/scene_datasets/habitat-test-scenes/skokloster-castle.glb

Looks like you have /path/to/habitat-sim in your PYTHONPATH. Please do unset PYTHONPATH (or similar) to remove it.

[c4chale]

I am having the same issue and neither if I have the /path/to/habitat-sim in my PYTHONPATH nor if I unset PYTHONPATH works.

Still the same error.

It seems like you didn't install habitat-sim. Please follow the instructions here: https://github.com/facebookresearch/habitat-sim#from-source

It seems like you didn't install habitat-sim. Please follow the instructions here: https://github.com/facebookresearch/habitat-sim#from-source

I did install it following the instructions.
I tried it installing it both inside the habitat-api folder and outside in the same folder where habitat-api is located but still having the same issue

[erikwijmans]

Just to clarify, you are currently running habitat-api's example script, not habitat-sim. Can you try to run python examples/example.py while in the /path/to/habitat-sim folder? That'll help reduce the number of variables. Also, please ensure you followed the habitat-sim build instructions while in that folder (i.e. not in the folder for habitat-api). If you installed into a conda/virtual/etc environment, please make sure that environment is activated.

Thank you,
Running python examples/example.py while in the /path/to/habitat-sim folder works perfectly.

[erikwijmans]

Is this with or without unset PYTHONPATH?

[c4chale]

Is this with or without unset PYTHONPATH?

My echo $PYTHONPATH returns empty since I reopen the terminal, so I guess with.

[erikwijmans]

When in /path/to/habitat-sim, what does echo $(cd examples; python -c "import habitat_sim; print(habitat_sim.__file__)") show?

[c4chale]

this is what it returns:

[erikwijmans]

Looks like you installed into a conda env named habitat. Please ensure that this environment is properly activated when you try to run things with habitat-api and please make sure you installed habitat-api in the same conda environment. Based on your current outputs, habitat-api was installed globally and you are likely not in this conda environment.

Hello! I'm in the same boat. I am installing habitat_sim (stable branch) on GCP. I got the python setup.py build_ext --parallel 2 --headless installed after a lot of work. It finishes install with the final message about magnum-0.0.0 successfully installed (which is consistent with other places I've installed it).

However, like above when I do pip list | grep habitat, I don't see it. And when I try to run any examples, I get

ModuleNotFoundError: No module named 'habitat_sim'

and when I add installed location to PYTHONPATH, I get the

ModuleNotFoundError: No module named 'habitat_sim._ext'

Thank you for your help in other issues thus far, it has helped me greatly. Any help here would be greatly appreciated!

[erikwijmans]

Looks like you forgot install in python setup.py build_ext --parallel 2 --headless, please try python setup.py build_ext --parallel 2 install --headless

[shahhaard47]

Thank you so much haha.

Hi All,

Thanks for all the info! Just to share my experience regarding the

ModuleNotFoundError: No module named 'habitat_sim'.

I am installing Habitat in a newly used laptop Alienware 17 R5 and installed CUDA 10.2 manually.

I followed the instructions in https://github.com/facebookresearch/habitat-sim#from-source. Initially, I was not able to build by python setup.py install --with-cuda, but I was able to do so by python setup.py install. However, when I run the test script by python examples/example.py --scene /path/to/data/scene_datasets/habitat-test-scenes/skokloster-castle.glb, I got the error ModuleNotFoundError: No module named 'habitat_sim'.

Then I removed, git cloned the repo and followed the same procedure until the setup steps. More specifically I installed by

python setup.py build_ext --parallel 2 install --headless

as mentioned and now I can run the example.py without any error.

[Derry-Xing]

from habitat_sim._ext.habitat_sim_bindings import Simulator as SimulatorBackend

ModuleNotFoundError: No module named 'habitat_sim._ext'

I still have the above issues after

python setup.py build_ext --parallel 2 install --headless
