Thanks, but could you print out the content of the UnsatisfiedLinkError?

saudet commented 6 years ago

In the example, where the error message is displayed.

roni762583 commented 6 years ago

Hi Samuel,

it appears once in a catch statement:

//setup the emulation environment through ALE, you will need a ROM file ALEMDP mdp = null; try { mdp = new ALEMDP("pong.bin");

} catch (UnsatisfiedLinkError e) { System.out.println("To run this example, uncomment the \"ale-platform\" dependency in the pom.xml file."); }

Is pong.bin a resource that is missing?

saudet commented 6 years ago

Yes, so please copy/paste the content of the UnsatisfiedLinkError object here, thank you.

You'll get an IOException if a file is missing, not an UnsatisfiedLinkError.

roni762583 commented 6 years ago

printing the error to string yields:

java.lang.UnsatisfiedLinkError: no jniale in java.library.path

saudet commented 6 years ago

Try to call printStackTrace() instead.

Exception in thread "main" java.lang.NullPointerException at org.deeplearning4j.rl4j.learning.sync.qlearning.discrete.QLearningDiscreteConv.(QLearningDiscreteConv.java:29) at org.deeplearning4j.rl4j.learning.sync.qlearning.discrete.QLearningDiscreteConv.(QLearningDiscreteConv.java:34) at org.deeplearning4j.examples.rl4j.ALE.main(ALE.java:87)

saudet commented 6 years ago

I'm not seeing any "UnsatisfiedLinkError" in that stack trace...

roni762583 commented 6 years ago

so what does it mean that System.out.println(e.toString()) outputs: java.lang.UnsatisfiedLinkError: no jniale in java.library.path while e.printStackTrace() outputs: Exception in thread "main" java.lang.NullPointerException at org.deeplearning4j.rl4j.learning.sync.qlearning.discrete.QLearningDiscreteConv.(QLearningDiscreteConv.java:29) at org.deeplearning4j.rl4j.learning.sync.qlearning.discrete.QLearningDiscreteConv.(QLearningDiscreteConv.java:34) at org.deeplearning4j.examples.rl4j.ALE.main(ALE.java:87)

? is the NullPointerException the UnsatisfiedLinkError?

saudet commented 6 years ago

The NullPointerException happens after, I want to know what happens before, the output of e.printStackTrace(). If you could simply copy/paste the whole output, that might help.

roni762583 commented 6 years ago

The following is everything I am getting on the IntelliJ console when attempting to run (I added the "output of e.printStackTrace():"

Thank you! As I suspected the rpath of libale.so wasn't adjusted properly to work Mac:

roni762583 commented 6 years ago

I don't find such a directory structure, is that in a file in the RL4J build?

saudet commented 6 years ago

It shouldn't be there, I've fixed the issue. Please try to use this dependency instead:

        <dependency>
            <groupId>org.bytedeco.javacpp-presets</groupId>
            <artifactId>ale-platform</artifactId>
            <version>20170911-6eddb8d-1.3.4-SNAPSHOT/</version>
        </dependency>
roni762583 commented 6 years ago

Saudet,

I changed the dependency, hit 'build project' on IntelliJ, and re-ran ALE, but the problem still shows. Below is the print out:

To run this example, uncomment the "ale-platform" dependency in the pom.xml file. output of e.printStackTrace(): Exception in thread "main" java.lang.NullPointerException at org.deeplearning4j.rl4j.learning.sync.qlearning.discrete.QLearningDiscreteConv.(QLearningDiscreteConv.java:29) at org.deeplearning4j.rl4j.learning.sync.qlearning.discrete.QLearningDiscreteConv.(QLearningDiscreteConv.java:34) at org.deeplearning4j.examples.rl4j.ALE.main(ALE.java:87)

saudet commented 6 years ago

The "ale-platform" artifact doesn't seem to get added at all to your build. Sounds like an issue with your IntelliJ IDEA. Could you please try from the command line?

I get the same error on windows:

i tried the other dependency (removed the trailing slash at the end in the version field) but i get still the same error

in which jar is the jniale.dll supposed to be? Is it possible that the binarys have been removed from maven repository due to license problems? Wouldn't be the first time

saudet commented 6 years ago

@wutzebaer ALE simply is not supported on Windows. Contributions are welcome though: https://github.com/mgbellemare/Arcade-Learning-Environment

saudet commented 5 years ago

ALE now works on Windows too, and works fine on Mac.
