I am doing image classification where images has a certain property or not (bool). how would I define INDArray labels for this? Seems pretty basic but wasn't able to find any answer that I would understand.

Hi all, I am new to ML and I am learning it by creating a project. I want to create a handwritten app, and for fun I want to do it for others language than english, I chose French and Arabic as I speak both> I am wondering how to create a dataset ? all the steps and how many sentences or words should I collect ? Thanks for you advices

Hi all, im new to ML and learning DL4J on a windows 11
so im trying to mvn clean install it, but i dont see there is any pom.xml in dl4j-examples folder

is there something that i missed?
im following tutorial here -> deeplearning4j.konduit.ai
Adam Gibson
@agibsonccc
@lyhnbomb could you post your problems on our community forums? https://community.konduit.ai/
Your problem isn't really clear. Your problem could be anything ranging from "how do I use maven and intellij" to "I want to build from source" the home page doesn't have anything specific on it. As dl4j is a library and not a desktop application you don't "install it" you "include it as a library in your favorite IDE or project"

I guess it is the memory error right? Is there any way to solve it or is it limited by the laptop configurations

@Purva-Chaudhari can you please migrate your questions to the community forum? https://community.konduit.ai/ at first guess it's an out of memory.

All, I am excited to invite you to the Joint OGC OSGeo ASF Virtual Code Sprint that is taking place 7:00am - 5:30pm EST from March 8th to 10th. The code sprint will focus on open standards and open source software. This will be a great opportunity to engage with software developers that might be interested in integrating Deeplearning4J into their Java-based software projects. The extended deadline for registration is 7:00am EST on March 8th. Please register at https://portal.ogc.org/public_ogc/register/220225asf_codesprint.php

I want config a multi-LSTM net with attentions like:

NeuralNetConfiguration.ListBuilder listBuilder = nncBuilder.list();
        int nIn = featuresCount;
        for (int i = 0; i < this.rnnNeurons.length; ++i) {
            listBuilder.layer(i, new LSTM.Builder().activation(Activation.SOFTSIGN).nIn(nIn).nOut(rnnNeurons[i]).build());            
            nIn = rnnNeurons[i];
            int nhead=8;
            listBuilder.layer(i, new RecurrentAttentionLayer.Builder().activation(Activation.SOFTSIGN).nIn(nIn).nOut(nIn).nHeads(nhead).projectInput(true).build());
        }

how should I set the param: setInputType(InputType.recurrent(size))?

Hi everyone, is it possible to import PyTorch model with Deeplearning4j? I can only find examples for Tensorflow/Keras https://github.com/eclipse/deeplearning4j-examples/tree/master/tensorflow-keras-import-examples . If it's possible, could you show me some instructions, thank you in advance!

Hi!

I'm trying to run nd4j on my linux machine but I'm getting this error:

UnsatisfiedLinkError
/home/webapp/.javacpp/cache/nd4j-native-1.0.0-M2.1-linux-x86_64.jar/org/nd4j/linalg/cpu/nativecpu/bindings/linux-x86_64/libjnind4jcpu.so: /lib64/libm.so.6: version `GLIBC_2.27' not found (required by /home/webapp/.javacpp/cache/nd4j-native-1.0.0-M2.1-linux-x86_64.jar/org/nd4j/linalg/cpu/nativecpu/bindings/linux-x86_64/libnd4jcpu.so)

With these imports

    // DeepLearning4j
    api("org.datavec:datavec-api:1.0.0-M2.1")

    implementation("org.nd4j:nd4j-native-platform:1.0.0-M2.1")
    implementation("org.deeplearning4j:deeplearning4j-core:1.0.0-M2.1")
    implementation("org.deeplearning4j:deeplearning4j-nlp:1.0.0-M2.1")

Anybody seen this before and any idea what's up

@RoytenBerge the forums at https://community.konduit.ai/ are a better choice to ask questions, as we don't monitor the channel regularly anymore. And there you'd have found this thread: https://community.konduit.ai/t/version-glibc-2-23-not-found-when-using-dl4j-cuda/1943 it is about a slightly older glibc, but the conclusion is the same: You are using a too old OS, and need to either update, or use the compat version
