Caused by: java.net.UnknownHostException: blob.deeplearning4j.org

how can i address this issue?

Thanks in advance

Solution

  • Replace this 

    String modelUrl = "http://blob.deeplearning4j.org/models/deepmoji.h5";

    to

    String modelUrl = "https://dl4jdata.blob.core.windows.net/models/deepmoji.h5";

    Then it should work !
