@seanysull_gitlab
googling that error leads back to boost issues. I do not have a clue what im doing in regard to boost to be honest. Any ideas on materials I might read to try and get up to speed?
Sean O'Sullivan
@seanysull_gitlab
also, how does using anaconda or a conda environment affect this?

Hi guys, I'm trying to find a tutorial for constructing a world with houses. Any ideas?
Andre Kramer
@AndKram
@seanysull_gitlab If you are using conda you could try MarLo (https://github.com/crowdAI/marLo) . These python wheels were built from https://github.com/nehaljwani/malmo-pip-pkg which may give you some more clues about building for your Linux/Python/Conda environment. Otherwise, please open an issue on GitHub malmo.

While installing malmo using cmake, almost all components install successfully except for 'Building minecraft' which always fails for 'fixMcSources'. It says 'Patching failed: minecraft\net\minecraft\util\math\Cartesian.java
Hunk 1 failed! Cannot find hunk target'
As a result I am unable to launch minecraft clients successfully.

More information:
"* What went wrong:
Execution failed for task ':fixMcSources'.

com.cloudbees.diff.PatchException: Cannot find hunk target

  • Try:
    Run with --info or --debug option to get more log output.""

Is this an issue with gradle? I am unable to proceed. This is on Mac OS X High Sierra
Andre Kramer
@AndKram
@pratikmehta14 It may be worth trying to clear your gradle cache: ./gradlew cleanBuildCache or delete ~/.gradle/cache.

Hi, I just try to run tutorial_1, and got this error"Failed to find an available client for this mission - tried all the clients in the supplied client pool" , and I went to the FAQ page, seems the reason is I got no mod in the mod list, how to fix this?

Hi, I'm trying to get multi_agent_test.py running, but it keeps showing "Not enough available Minecraft instances running." How to fix it?

Hi, I'm wondering if anyone could help me get Malmo working. My problem is that I don't know how to get boost_python35, and as far as i know Malmo doesn't support python3.6, are they planning to? I am at step 7 viii of this page https://github.com/Microsoft/malmo/blob/master/doc/build_linux.md getting: "Could not find the following static Boost libraries: boost_python35" Im running ubuntu 18.10, my system does however have libboost_python[27, 36, 37] at /usr/lib/x86_64-linux-gnu

Hello everyone, I am currently considering Project Malmo for long-term use for my PhD research. I was wondering if there is any information on whether this is going to be actively maintained? Thanks in advance!
Andre Kramer
@AndKram
@this-guy-0 There are binary releases available if you don't want to build form source otherwise a good starting point would be the docker build script for Ubuntu 18 (https://github.com/microsoft/malmo/blob/master/scripts/docker/build_ubuntu1804_python3.dockerfile).
Andre Kramer
@AndKram
@WenhanKong Have you started the right number of Minecraft instances (on ports 10000 and 10001, 10002 etc)?
@VictorZhaointhehouse Can you make sure that you have Minecraft running. Possibly it's still handling a previous mission (it's output & logs would tell you) so restarting Minecraft may help.
Sean O'Sullivan
@seanysull
@this-guy-0 I had trouble building from source but got the pre built version working easily.
@AndKram Is it possible to get the distances between the player and the blocks surrounding them in a similar fashion to how you can get the types of the surrounding blocks?

  • Where:
    Build file 'C:\Users\jagat\Downloads\malmo-master\malmo-master\Minecraft\build.gradle' line: 18

  • What went wrong:
    A problem occurred evaluating root project 'Minecraft'.

    version.properties file is missing - this is created automatically by CMake. If you are building from source, make sure you have built the full source tree, not just the Minecraft folder.

  • Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

I met this problem when I run "./launchClient.bat" in my anaconda powershell prompt.
how can I get a version.properties file?
Thanks in advance!
I've install malmo in my windows10 system by "pip3 install malmo"
And I can also import malmo in python

@PlatinumNinja72
Hello all,
I'm looking to base my own evolution simulation on the Malmo project base, but I need to know a few things before setting out:
Firstly, due to the continuous nature of my simulation I would need to be able to add new agents during the simulation that may not be defined before the start. Is the AgentSelection definition too rigid for this to occur?
PlatinumNinja72
@PlatinumNinja72
Second, if it turns out that you must define every agent at the time of initialization, must all clients be connected before the environment can begin? If I were to define 20 clients, but only use 15 at the beginning of the simulation, would I be able to introduce the rest at a later date?
Thank you in advance!
Andre Kramer
@AndKram
@PlatinumNinja72 Currently all the agents are declared in the mission XML (as you observe) and the mission startup waits for all of them to turn up. I'd also add that the agents are relatively heavy weight as each requires an instance of Minecraft to be running and failures result in missions ending so having as many as 20 agents could be somewhat problematic.

Hello, I'm trying to launch a malmo gym environment from a headless server. I've tried to install various xorg packages and currently are trying to instantiate a monitor emulator (I think) with the command Xvfb :1 -screen 0 800x600x16 & but when trying to instantiate a gym environment (MineRLNavigateDense-v0) I get the following error

Caused by: java.lang.RuntimeException: org.lwjgl.LWJGLException: Could not open X display connection

After this, the python throws an error and says

RuntimeError: ERROR! MineRL could not detect an X Server, Monitor, or Virtual Monitor! 

In order to run minerl environments WITHOUT A HEAD use a software renderer such as 'xvfb':
        xvfb-run python3 <your_script.py>
    ! NOTE: xvfb conflicts with NVIDIA-drivers! 
    ! To run headless MineRL on a system with NVIDIA-drivers, please start a 
    ! vnc server of your choosing and then `export DISPLAY=:<insert ur vnc server #>

If you're receiving this error and there is a monitor attached, make sure your current displayvariable is set correctly: 
         DISPLAY=:0 python3 <your_script.py>
    ! NOTE: For this to work your account must be logged on the physical monitor.

If none of these steps work, please complain in the discord!
If all else fails, JUST PUT THIS IN A DOCKER CONTAINER! :)

But I'm trying to get this to work through a docker image which serves a jupyter notebook (since we are doing a tutorial on RL). Does anyone have any idea on how to make the docker image start an x-server correctly?

I'm a bit over my head with this, so sorry if the solution is simple.

Andre Kramer
@AndKram
@IsakFalk You might want to look at the docker examples in https://github.com/microsoft/malmo/tree/master/scripts/docker. There's one (https://github.com/microsoft/malmo/tree/master/scripts/docker) that installs VNC so that you can view it remotely. There are instructions how to run and connect to it near the end of https://github.com/Microsoft/malmo/blob/master/scripts/python-wheel/README.md.

@AndKram Thanks Andre, I found the repo and it's working now.

Could I know is there a way to retrieve the size of the Minecraft World created? I would like to reproduce the whole world as a symbolic view similar to what has been done in the Microsoft Malmo: ai-challenge:PigChase in the environment. However, the world that I would like to visualize is larger and the world size is unknown.
Shreyas Lad
@PenetratingShot
Well the default world size is known

Hey guys! I'm trying both Minecraft and Malmo for the first time ever! I think that I have everything installed, I can run python3 tutorial_1.py and see the agent "doing nothing". Then, I followed "3 Get moving" from Tutorial.pdf, the agent does move but, there is an error: "Error: AgentHost::sendCommand : commands connection is not open. Is the mission running?", is it normal?
I added the "move lines" within the while world_state.is_mission_running: loop.
I'm also seeing that this chat is kinda empty... Is there a more active channel?

tutorial_6.py is awesome!!! LOL
