Re: [Dev] [ML] Getting Error on executing sample of Java Client

Hi,

In order to run the model usage sample, first you have to create a model
using the Machine Learner using the dataset (pima-indians-diabetes dataset)
and the algorithm (Logistic-Regression) with response variable (Class)
indicated in the sample. Then replace the downloaded-ml-model in
src/main/resources/ folder with the model you have generated. That way you
can use the model built with the ML version you have currently.
We have also updated the model in the resources folder[1].

Best regards.

[Dev] [ML] Getting Error on executing sample of Java Client

2015-12-19 Thread NIFRAS ISMAIL 
Hi,

I have use wso2 ML 1.0.1 to create the model. Now i need to build a java
client to read the model in my project.

I have try to execute java client sample which is provided by carbon-ml git
repo of wso2.
https://github.com/wso2/carbon-ml/tree/master/samples/model-usage

The project is build successfully using mvn clean install

while on exection it gives this error . I am using ideaJ to execute
the MLModelUsageSample
class.

Exception in thread "main" java.io.InvalidClassException:
org.wso2.carbon.ml.core.spark.models.MLClassificationModel; local class
incompatible: stream classdesc serialVersionUID = -5405685346474685046,
