I'm trying to implement Active Neural SLAM by following the Github post. But has the following error. Please help me if any solution.....
I'm using ubuntu 18.04, python 3.6.9
Got this error when checking the dependencies ----- sudo python3 main.py -n1 --auto_gpu_config 0 --split val

This seems to be an issue with habitat installation. Quick way to check this is by running examples/benchmark.py in habitat-api directory (where you installed habitat-api, not the submodule within Neural-SLAM directory). If it throws an error, it indicates habitat-sim or api is not installed correctly.
Thank you so much for the response.
We got succeeded in the installation of Habitat-sim and Active Neural SLAM.
By using a virtual python environment problem got resolved. (venv).
Python version was also upgraded to >=3.7
Earlier wrong version of python was used for compiling.
When using setup.py, we need to run that command outside the root repo folder, otherwise, you'll pick up the source instead of what was installed, possibly causing conflicts.
sorry to bother you again.
We have another issue.

BrokenPipeError: [Errno 32] Broken pipe
Is this error because of pickle or memory?
Do we need to update habitat-sim?
We have changed the slam memory size ('-sms', '--slam_memory_size') but did not succeed.
Looking forward for your reply.
Thank you so much
This looks like a pickle error and seems unrelated to habitat-sim.
