Exception in thread "main" java.lang.UnsatisfiedLinkError: no jnind4j in java.library.path #1658

I created a simple code with DeepLearning4J that works in my Mac OS but when I go to my linux machine (to run real experiments), I see the following error:

I suspect that you have build an uberjar on your mac?

As maven doesn't know where you are going to deploy, it only packages stuff for mac.

In order to use your uberjar on a linux system, you will have to add the following dependency:

<dependency>
    <groupId>org.nd4j</groupId>
    <artifactId>nd4j-native</artifactId>
    <version>0.4-rc3.10</version>
    <classifier>linux-x86_64</classifier>
</dependency>

After adding the dependency, I see a slightly different error (Caused by: java.lang.UnsatisfiedLinkError: /tmp/javacpp12515585121209620/libjnind4j.so: /tmp/javacpp12515585121209620/libgomp.so.1: version `GOMP_4.0' not found (required by /tmp/javacpp12515585121209620/libnd4j.so)):

What version of Linux are you using?

saudet commented 8 years ago

And please try to upgrade nd4j.version to 0.4-rc3.10

Still having the problem after upgrading the nd4j.version

I've just tried it in a fresh Docker container, and dl4j-0.4-examples works fine on Ubuntu 14.04. Does dl4j-0.4-examples also fails on your machine?

rasoolims commented 8 years ago

I tried the examples in MAC (both from cmd and from IntelliJ) and the examples ran correctly.

BUT in linux:

Look at that last part...this looks REALLY suspicious: Caused by: java.lang.NoClassDefFoundError: org/codehaus/plexus/util/Os

Could you try upgrading your maven maybe?

rasoolims commented 8 years ago

Ok, now after updating Maven, I could successfully run the examples but I still have the same problem when running my code (i.e. Caused by: java.lang.UnsatisfiedLinkError: /tmp/javacpp12671829276729217/libjnind4j.so: /tmp/javacpp12671829276729217/libgomp.so.1: version `GOMP_4.0' not found (required by /tmp/javacpp12671829276729217/libnd4j.so))

I also ran in a friend's machine (it ran ok on his laptop Linux but could faced the same problem when he ran on a server linux machine):

Linux version 3.13.0-85-generic (buildd@lgw01-32) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #129-Ubuntu SMP Thu Mar 17 20:50:15 UTC 2016 No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.4 LTS Release: 14.04 Codename: trusty

My only guess is that both of our servers don't have any GPU drivers and I am adding some GPU-specific maven dependencies in the POM.xml file. Is that right?

agibsonccc commented 8 years ago

Upgrade your maven please.

rasoolims commented 8 years ago

Finally solved it: I had to specify ${basedir}/src/ so Maven confused about the main directory.

Thanks

saudet commented 8 years ago

@rasoolims It's probably not related to GPU, Maven version, or source code directory. If the examples are working fine, but your own pom.xml isn't, it's mostly likely because your pom.xml file makes Maven use an old version of DL4J. Just base your pom.xml file on the examples, and everything will work fine!

cqiang5882 commented 7 years ago

@rasoolims hello i am meeting the same problem and can you show ur final pom.xml,thank u very much
