MINOS is a simulator designed to support the development of multisensory models for goal-directed navigation in complex indoor environments. MINOS leverages large datasets of complex 3D environments and supports flexible configuration of multimodal sensor suites.
Use the I/J/K/L keys to step and turn, the arrow keys to strafe and look up or down, the R key to respawn, and the O key to update the agent observations panel on the right. The M key toggles various navigation grid and shortest path visualizations.
Installing
MINOS can be used on Linux and MacOS systems. Use under Windows is possible but not recommended.
Request and download the SUNCG and Matterport3D datasets. Please indicate "use with MINOS simulator" in your request email. For Matterport3D, use the invocation download_mp.py --task_data minos -o . with the provided download script. This will download a 5.1GB zip archive which expands to approximately 6.3GB. For SUNCG, by default the download_suncg.py script will download the latest version of the dataset. You can obtain the v1 or v2.0 versions using download_suncg.py --version <version>.
Install node.js using the Node Version Manager (nvm).
If you use zsh instead of bash, replace all instances of bash with zsh. Confirm node installation is succesful using node -v at the terminal.
Build the MINOS server modules by running npm install inside the server directory. This process will download and compile all server module dependencies and might take a few minutes. There are some prerequisites for the build process in Ubuntu, they can be installed using sudo apt-get install build-essential libxi-dev libglu1-mesa-dev libglew-dev libvips.
Make sure you have a Python3 installation with pip3 available on your command line. The following steps can be carried out in a virtualenv, or with the system python installation.
Install the minos Python module by running pip3 install -e . -r requirements.txt in the root of the repository.
Extract the SUNCG and/or MP3D data packages under $HOME/work/suncg and/or $HOME/work/mp3d, or under another parent directory of your choice. If you choose a directory other than $HOME/work as the dataset parent directory remember to run all remaining commands with the prefix NODE_BASE_URL=path/to/data_parent_dir.
Check that everything works by running the interactive client through python3 -m minos.tools.pygame_client, invoked from the root of the repository. You should see a live view which you can control with the W/A/S/D keys and the arrow keys. This client can be configured through various command line arguments. Run with the --help argument for an overview and try some of these other examples:
python3 -m minos.tools.pygame_client --empty_room : navigation in empty SUNCG environments
python3 -m minos.tools.pygame_client --dataset mp3d --scene_ids 17DRP5sb8fy --env_config pointgoal_mp3d_s : an example Matterport3D environment
python3 -m minos.tools.pygame_client --depth -s normal -s objectId -s objectType -s map --navmap --width 128 --height 128 : multimodal agent with depth, normals, object instance and category frames
Documentation
See the API document for an overview of the Simulator API and a reference of the available configuration parameters. Please also refer to the FAQ document for answers to common questions and resolutions for common errors.
OpenAI gym example code
We provide a demo gym wrapper of MINOS in gym/demo.py. Install by running pip3 install -e . in the gym directory. Run through python3 demo.py. Various configuration options are available and documented in the --help information. For example, you can run the room goal task in small Matterport3D environments using:
python3 demo.py --env_config roomgoal_mp3d_s
Or run the object goal (door target) task in medium furnished SUNCG environments using:
We provide a collection of scripts that are useful for setting up experiments, benchmarking, and visualizing agent episodes. The scripts provide --help documentation.
Presampling episodes for reproducible testing
minos/tools/generate_episodes.py - Presamples agent episodes (start states and goals) and produces a CSV format file that can be used as a parameter to the states_file task configuration option.
minos/server/check_episode_states.js - Checks presampled agent episodes to verify navigability.
Exporting precomputed resources
minos/server/export_navgrid.js - Exports precomputed navigation maps (will need to be computed and exported for scene sets other than the ones provided in the repo):
Benchmarking scripts to test the performance of the simulator:
minos/server/benchmark.js - Use to benchmark the javascript server component in standalone mode.
minos/tools/benchmark.py - Use to benchmark client-server communication through SocketIO. Allows for specification of sceneIds and episodes per scene to go through, various simulator configurations (sensory inputs to enable, rendering options) and for running with multiple simulators.

Hi, I am trying to run the code but it gives following messages. Though they are not "ERROR" messages, nothing happens. Could you help me out with this error?

Actually, it seems to be a problem while connecting the socket, so I tried to manually run the node server in separate terminal by typing in node server.js -p 17226 inside the server directory. Then the python gives following message and stops to throw warnings. But it still does not pop up any windows or give anything.
2017-12-27 22:57:11,571 INFO Starting new HTTP connection (14): localhost

I found useful to retrieve necessary information form sensors, which I can get from sensors.
For example, to get rgb image observation I do observation['observation']['sensors']['color']['data']
But resolution of output data (arrays) is (128, 128). After trying to change resolution of observations rendering from simulator in sensors.yml as well as via env_config files, I didn't reach any solution.
Could you please tell more about resolution changing (for observations, not for environment rendering via end.render(mode='rgba_array'))?
I want to print the position and angle of agent , just like nvmap command is providing. If I could save them in excel or text form or could display them on terminal continuously.
I am trying to run MINOS demo.py in /gym on headless Linux machine with NVIDIA GPU card.
I have two settings, which one works fine and the other have the exact same issue with Linux Machine without Xserver of @XL2013 in #3 .
The command I run was below
NODE_BASE_URL="somepath" xvfb-run -s "-ac -screen 0 1280x1024x24" python3 demo.py --env_config objectgoal_suncg_mf
It worked perfectly fine when I run the command on the node of headless Linux server I am sshing.
However, when I run the same command on the node of same server with NVIDIA GPU card, I cannot have WebGLRenderer correctly working and the log of simserver.log is attached below, which is equivalent to that of @XL2013.
If anyone has any ideas to get this working, that is very appreciated.
Thanks in advance.
Hi! Following error occurs while running MINOS. I tried reinstalling Python3 but it had no effect, I've installed Anaconda as well.

When I save action_trace file, there is column of rotation, what does it means? the rotation is in degrees or radians ? Looking forward for the reply !
Hello, as written in the paper I got the field of view for the agent is 90, but what is the angle of view of the agent? Is this also 90 degrees, and where exactly on the code are they specified (could you probably point me to the script or text file)? Thanks for your response in advance.
When I replaced the add_sim_args_basic with add_sim_args, I got the following error
