Hi everyone, I've installed MalmoEnv in Google Cloud Platform and I'm trying to start it using python3 -c "import malmoenv.bootstrap; malmoenv.bootstrap.launch_minecraft(9000). However it remains stuck in the following line **[17:12:25] [Client thread/INFO]: [STDOUT]: CLIENT request state: DORMANT
[17:12:25] [Realms Notification Availability checker #1/INFO]: Could not authorize you against Realms server: Invalid session id
[17:12:25] [Client thread/INFO]: [STDOUT]: CLIENT enter state: DORMANT

Building 95% > :runClient**. I don't know whats wrong. Could anyone help me please?

@AndKram
@u-pi Not in Malmo but possibly another Minecraft Mod could be used to create the world.
@Lolits Hi, you've launched Minecraft and it's waiting for the agent to connect. You can use another shell/terminal session to do: python3 -c 'from malmo.run_mission import run; run()'

Hi everyone! I'm trying to build Malmo and I'm stuck at Step 7 in "Building on Linux" guide while getting an error indicating nonexistent file:

ninja: error: 'Malmo/src/JavaWrapper/com/microsoft/msr/malmo/AgentHost.java', needed by 'Malmo/src/JavaWrapper/CMakeFiles/MalmoJavaJar.dir/java_compiled_MalmoJavaJar', missing and no known rule to make it

Is there any way I could fix it?

Andre Kramer
@AndKram
@kirillbobyrev It's simpler to use a pre-built version (such as the malmo pip package) as in "Getting Started" on https://github.com/Microsoft/malmo. If that's not possible you could follow the build instructions (https://github.com/Microsoft/malmo/blob/master/doc/build_linux.md) and look at the docker build examples in malmo/scripts/docker. Looks like it's failing to create the Java wrappers for AgentHost for some reason.
Kirill Bobyrev
@kirillbobyrev

@AndKram Thank you! I was actually following the guide you have linked.

I have tried again with Makefiles (instead of Ninja) and I didn't have this error anymore. I had the other one, though, but that is probably related to Boost being newer than the one used by developers.

Because I'm using system Boost. Should probably try to build the earlier version.
Sean O'Sullivan
@seanysull_gitlab

I am trying to follow the build instructions for linux at https://github.com/Microsoft/malmo/blob/master/doc/build_linux.md I have got to the point where I try to run the command : "cmake -DBoost_INCLUDE_DIR=/home/$USER/boost/boost_1_66_0/include -DCMAKE_BUILD_TYPE=Release .."

which fails giving me the error:

CMake Error at /usr/local/share/cmake-3.11/Modules/FindBoost.cmake:2044 (message):
Unable to find the requested Boost libraries.

Boost version: 1.66.0

Boost include path: /home/sean/boost/boost_1_66_0/include

Could not find the following static Boost libraries: boost_python36

I also tried to install using pip which gave the following : ERROR: Could not find a version that satisfies the requirement malmo (from versions: none)
ERROR: No matching distribution found for malmo

Hi, I'm trying to install on mac OSX using instructions on https://github.com/Microsoft/malmo/blob/master/doc/build_macosx.md.

When I run cmake, I get the following error:
""""

-- The CXX compiler identification is unknown
-- Check for working C compiler: /usr/bin/cc

It fails with the following output:

Any idea why cmake is complaining?
Pratik Mehta
@pratikmehta14
It was an issue with xcode, fixed.
Andre Kramer
@AndKram
@seanysull_gitlab Do you have the boost library for Python installed for your version of Python (3.6 from looking at your error)? You could have a look at the docker build scripts for your version of Linux. https://github.com/microsoft/malmo/tree/master/scripts/docker. There is a good chance that Python lib has another name e.g. just boost_python3 so you could check what's installed and modify the CMakefile.txt appropriately:
set( BOOST_PYTHON_NAME "python3" CACHE STRING ${BOOST_PYTHON_NAME_DESC} )
sasinha
@sasinha
@stevenwernercs Were you or anyone here able to find a list of strings that AgentHost.sendCommand takes in?
Andre Kramer
@AndKram
@sasinha It depends on whether commands are discrete or continuous. One such list is in https://github.com/microsoft/malmo/blob/master/MalmoEnv/malmoenv/commands.py
Sean O'Sullivan
@seanysull_gitlab

@AndKram Thanks for your reply, I changed the CMakeLists.txt (I thought this was what you were referring to when you saidCMakeFile.txt) to what you suggested (with "python" instead of python3) and it builds successfully, however, after building i tried to run the command ctest and the majority of the tests fail:

additionally if i try to follow the tutorial when i try to run "sean@sean-HP-Z240-Tower-Workstation:~/MalmoPlatform/build/install/Python_Examples$ python tutorial_1.py" I get the following error:

Sean O'Sullivan
@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

    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 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
