    hey guys, I'm working on a Golang library for MLeap, to begin with I'm trying to bring Word2Vec models. So far my problem has been to understand how the JSON model is parsed, is there any documentation about this?

    "Failed to find a default value for splits", any one meet this problem while save model with mleap?

    @prafulrana21 at the moment it seems we don’t have an endpoint for that if you’re using the spring boot service (https://github.com/combust/mleap/tree/master/mleap-spring-boot). Let me know if you’re interested in adding one!

    Hi @here, I’ve just released the latest version of mleap (0.16.0), both the scala projects and the pypi package. Release notes are under https://github.com/combust/mleap/blob/master/RELEASE_NOTES.md, thank you all for your contributions and support! Will be updating the documentation in the next few days.

    Hi, @here. Is there any example how to serialize trained tensorflow model to mleap bundle? Documentation proposes to use tensor flow freeze_graph function. But it's unclear how it can be used to generate mleap bundle.

    Does anyone know how to get back a RandomForest model written in Scikit-Learn please? I would like to use Pyspark to do that. But I can't find a good way to do that.

    Did anyone ever try to save an XGBoost4J model (as part of a Spark pipeline - Bundle.ml) and load it in a docker for REST API? I'm having some difficulties...
    @ancasarb can you kindly assist?
    Thank you!

    Hello. I'm still stuck. Do you know if it is possible to save a model/pipeline with Scikit-Learn in zip? I can't find a way to do that. Thank you.

    I found a solution. My problem was linked to "databricks". If anyone else is interested, I explained my workaround here: combust/mleap#690

    i am trying to use mleap to log a logistic regression (pyspark.ml.classification.LogisticRegression) model by doing mlflow.mleap.log_model(spark_model=model, sample_input=test_data.limit(1), artifact_path=SAGEMAKER_APP_NAME), and then doing a deploy to SageMaker. But when i use boto3 to make the prediction call, the SageMaker endpoint only returns the prediction label 1 or 0, without the probability value. Is there anywhere i can look into to debug this problem?

    java.util.NoSuchElementException: key not found: org.apache.spark.ml.PipelineModel, does anyone met this problem?
    use mleap-spark_2.3.0, seriazation pipelne mode in local environment is success, while failed on cluster mode
    and if it seems reference.conf in mleap-xgboost-spark overwrite reference.conf in mleap-spark
    @Daniel8hen have get any resolution?

    Hi Guys,

    Is there any way, where we can load models if mleap runtime is added as a dependency in java app? Couldn't figure out from looking at the java doc available.

    Could only find API way of loading the models.

    Hello everybody :)

    I am new to this chat. I was reading the MLeap documentation and I really think it's a great product. My only concern is that (as far as I know) it's not possible to use Spark-NLP annotators or any other python NLP package. Did anybody manage to build a pipeline with a Lemmatizer or any other processing step which is not included in default Spark ML or sklearn modules?

    Is there any way of serializing List[String] in a separate folder like being done in DecisionTree and GBT like serializers.

    hi folks - is there a rough sense of when JDK11/Spark3 support may be added as per combust/mleap#475 ? thanks so much
