malmo's Issues

"attack 1" command auto-repeat doesn't work until user has clicked on Minecraft window

DrawItem inside air block fails most of the time.

No Mission.h on Mac OS

make fails almost immediately with no <Mission.h> referenced from MissionSpec.h while building AgentHost.cpp. Is it supposed to be generated from the schema?

Cmake also generated a warning for XSD_LIBRARY definition missing, so I did this the following which I'm not sure was correct.

cmake .. -DXSD_INCLUDE_DIR=/Users/.../code/xsd/libxsd/ -DXSD_LIBRARY=/Users/.../code/xsd/bin/xsd

Requesting depth map breaks recorded video

Feature request: A mission builder mode in the Mod

In this mode, the user would be able to use their Minecraft characters to build the arena they want to use for their AI experiments.

Features:

Start position
Goal position(s)
Limits of drawing
Way to save out the mission

Incorrect URI for FileWorldGenerator leaves client in error state

If the Mission XML includes, for example:

<FileWorldGenerator src="invalid_path/arena" />

Then the Minecraft client enters ERROR_CANNOT_CREATE_WORLD and must be restarted.

Sample mission automatically resized the windows to the smallest size on Windows 10

When I started running the sample mission using the given jar or python file, the windows always resized to the smallest size like this.

Release crashes with seg fault 11 with Anaconda Python on Mac OS

MalmoPython ImportError: Undefined Symbol _ZN12ALEInterface9game_overEv

I downloaded the package for Ubuntu 14.04 64-bit as per the instructions. I then installed ALE according to the readme.html file.

I then open Minecraft by running: ./launchClient.sh
Finally, I execute the python agent using: python runMission.py

I get the following error:

Any ideas?

Mac: launchClient.sh fails with error message

My configuration:
MacOS 10.9.5
$ java -version
java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)
$ javac -version
javac 1.8.0_92
Environment variable JAVA_HOME is not set.
I get the same error message with the release 0.11.1 and with the repository snapshot bedd292. The (lengthy) error messages follows:

$ ./launchClient.sh
./launchClient.sh: line 40: run/config/malmomodCLIENT.cfg: No such

Duplicated code in SWIG wrappers for different languages - merge

Mission string not checked for equality in multi-agent missions

Rare cases where messages arrive on the wrong port

Very occasionally we see the situation where observations arrive on the mission control port, for example. Other combinations too. These messages are rejected but that means losing data for that mission.

Grid observer is unusably slow

Adding the following grid observer:

<ObservationFromGrid>
<Grid name="Blocks">
<min x="-10" y="-10" z="-10"/>
<max x="10" y="10" z="10"/>
</Grid>
</ObservationFromGrid>

(21 x 21 x 21 = 9261 blocks per observation) to my mission slows down the game (or the Malmö mod?) so much that the system is unusable. I see two possible behaviors, and I did not figure out yet when I get which of the two:

The controller keeps sending commands, but the game freezes for up to several seconds, then moves on for very few frames, then freezes again.
The controller keeps spitting out commands, the game keeps moving, but the new commands are ignored and the game keeps repeating the very first commands (key press state).

Reporting 10K blocks should not be a big deal, even at 20Hz, compared to rendering the scene. So I suspect that there is probably a source of inefficiency somewhere. The problem is "scalable" in the sense that requesting fewer blocks results in shorter lags, but also for 1K blocks the lags are clearly percievable.

Support loading of world files

Code for doing this locally exists, needs to be integrated with minecraft client-server setup (allow for caching)

Malmo's internal Minecraft client/server message system can't send more than 64k per message

MalmoMessage.toBytes() uses ByteBufOutputStream.writeUTF() to encode message data.
From the docs:

First, the total number of bytes needed to represent all the characters of s is calculated. If this number is larger than 65535, then a UTFDataFormatException is thrown.

Alas, the limit of 65535 can easily be surpassed by requesting a large grid observation (21x21x21 will do it, depending on the blocktypes of the terrain). The effect in this case is that the observations never reach the agent.

In Torch, printing any class leads to quitting Lua

Ubuntu 14.04

After requiring 'libMalmoLua', if we init a new variable like 'a=AgentHost()', and then simply 'print a', or if you type in an interactive environment ' AgentHost() ', which will try to print the output, the program will crash and quit Lua.

This is possibly because something like a __ tostring() __ function is undefined, but I'm not sure.

Cannot launchClient with error - liblwjgl.so: wrong ELF class: ELFCLASS32

The installation works fine, and it passed all tests. However, when I do ./launchClient.sh, it fails with the following error:

Unable to launch java.lang.reflect.InvocationTargetException
...
...
at GradleStart.main(Unknown Source) [start/:?]
Caused by: java.lang.UnsatisfiedLinkError: liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)
...
...

I also checked online and tried different versions of liblwjgl, but the problem remains.

Very short missions can break the server state machine

When this happens the clients must be restarted.

World creation needs a "force reset" flag

As an optimisation, Malmo won't recreate the Minecraft world unless it decides it's not suitable for the requested mission. The result is that changes introduced in one mission will carry over to the next. In many cases this is a non-issue (eg when the agent makes no changes to the environment), but there will often be situations where a full reset is desired between missions.

We should add a flag to the XML for:

FlatWorldGenerator
FileWorldGenerator
DefaultWorldGenerator
to force world recreation.

[Implementation details: Flat/File/DefaultWorldGeneratorImplementation.shouldCreateWorld() should return true if this flag is set.]

Release crashes with Brew Python on Mac OS

Maximizing the Minecraft window degrades the video quality

We prevent the Minecraft window from being resized using the border but not from being maximised, or minimized and restored. These actions cause Minecraft to change the rendering viewport to the window size. Since we are blitting the frame buffer to the desired size, this causes a scaling to be applied to the image in these cases, which will degrade the video quality, potentially affecting the results of the agent vision.

Possible solutions:

Find a way to prevent maximise and minimize actions.
Find a way to render separately without affecting the window display or the framerate (don't want to render twice).

Workaround: Don't maximise the window. Minimizing is fine as long as you leave it minimized during a mission.

Building Malmo from Source MacOS

Hey everyone,

I'm having trouble building Malmo from source.
I've managed to run the MacOS release just fine, but i'd like to build from source so
I can try to solve #11.

I'm having the same issue as describe in #35

Here is my error message:
make

I've followed the instructions as shown in the travis script

If agent is disconnected for chat spamming, the server is left in a broken state

Likewise if one agent is booted if same login is reused.

The only way to recover from the resulting state is to restart the Minecraft clients.

Mac - Python crashes immediately

With the download version, both Brew python and Anaconda python crash pretty quickly with run_mission.py.

Note I still can't build either in linking libMalmoNETNative.so due to some boost errors. But I do have boost installed through Brew.

Cpp sample works fine.

Rare possibility for messages to arrive from wrong mission

Currently we don't validate each message as having a) come from the correct mission, b) come from the expected source, c) come in the right order, and d) come at all.

Suggestion:

Every message is appended with a message number and a unique mission ID that is generated by the AgentHost and sent in the MissionInit.
Any message with the wrong mission ID is rejected (by both the Mod and the AgentHost).
Any message with a non-sequential message number causes an error.
The MissionEnded contains the number of messages of each type that were sent/received by the Mod. If the number is not as expected then the AgentHost throws an error, which the user can deal with as desired.

Allow XSDs to be stored somewhere else instead of in same folder

Suggestion: use an environment variable

require 'LibMalmoLua' leads to segmentation fault

System: Ubuntu 14.04
Using the Malmo release version with ALE
Torch: updated a week ago, a very recent version

After requiring the lib, it simply gives ''segmentation fault (core dumped)'' and quits lua.

The Malmo release version without ALE does not have this problem.

Cannot change temp directory for mission record

By default it saves to a mission_records folder in the same place as the executable. But depending on permissions etc. this might not be what you want.

Suggestion: Use a new MALMO_TEMP environment variable for this.

This may just be a configuration problem on my side, however, I have no idea how to debug this. I'd like to have a successful build on my system, and I would be willing to disable the C# part if possible. For now this is low-priority, since launchClient.sh works.

Lua and Torch not supported on MacOSX

Minecraft window needs focus else doesn't receive key commands (use, attack).

Rewards and observations are sometimes received after the mission has ended

Mod should reject mission request with error if matching Mission and ExperimentUID

Mod client with integrated server running should give MALMOERROR to any MissionInit looking for its server that has matching Mission and ExperimentUID since this is a dangerous situation and the researcher should give each instance a different ExperimentUID.

Multi-process builds occasionally fail

Many build systems support building parts of the project in parallel. By default on the command-line our builds use only a single process. If you enable multi-process builds then occasionally the build will fail.

Solution: fix CMake dependencies so multi-process builds work reliably.
Workaround: build again until succeeds.

To enable multi-process builds:

In Visual Studio IDE: on by default.
In msbuild: e.g. /maxcpucount:10
In GNU make: e.g. -j 10

CommandForWheeledRobotNavigation initialises pitch/yaw to 0, regardless of values in XML

WorldFromDefaultGame should ignore the XML start pos in favour of the spawn point.

Slowdown in framerate after 500+ missions

To reproduce:

python tabular_q_learning.py

Use F3 to turn on framerate display in Minecraft. Starts at 60fps, drops to 34fps after 500 missions. Overnight it drops further. This is a new issue, suspect introduced by the frame sizing changes.

For multi-agent missions, should be able to reserve clients before launching.

Currently each agent finds a client in turn, which then all wait for the agents to join the mission. This will go wrong if there aren't enough clients available, or if there are two researchers launching multi-agent missions who then hit a deadlock situation.

CMake fails when disabling MalmoPython

In commit 7c19d43 I tried to disable MalmoPython since it gives linker errors on my system (I'll investigate and possibly open a separate issue for that) and I use C++ anyway. I am on MacOS 10.9 with clang 3.5 and boost obtained through homebrew. The following happens:

$ cmake -DPYTHON_ENABLE_MODULE_MalmoPython=OFF .
-- Boost version: 1.60.0
-- Found the following Boost libraries:
--   chrono
--   date_time
--   filesystem
--   iostreams
--   program_options
--   python
--   regex
--   system
--   thread
--   atomic
-- Found the following C# Mono versions: 4.4.0

 ====   WARNING: ====

 ALE was not found! Build will proceed but without the ALE parts included.

-- Using Mono compiler version 4.4.0

CMake Error at Malmo/src/PythonWrapper/CMakeLists.txt:11 (target_link_libraries):
  Cannot specify link libraries for target "MalmoPython" which is not built
  by this project.

The same happens when disabling the option from the ccmake gui. I assume that the ALE warning can be ignored (I don't intend to use ALE). Somehow the option does not seem to properly disable the MalmoPython module, at least I wonder why cmake even enters the folder Malmo/src/PythonWrapper at all.
