Thank you for reporting this. This is definitely a bug related to the recent serialization changes we made for our models. We will try to fix it asap.

In the meantime you can try using 0.5.x version.

shoafj7917 · 2019-10-09T22:00:59Z

Is there a timeline when this will be fixed?

tovbinm · 2019-10-10T18:25:02Z

This requires changing our code generator templates for feature engineering in CLI so it would generate the concrete feature extractor classes. Perhaps @vpatryshev or @wsuchy can have a look?

vpatryshev · 2019-10-10T18:26:44Z

Sure can do; can I have more details?

tovbinm · 2019-10-10T19:55:06Z

@vpatryshev it's similar to what @gerashegalov done here in this PR - #406

For example this extractor code with anonymous function:

val rowId = FeatureBuilder.Integral[BostonHouse].extract(_.rowId.toIntegral).asPredictor

Has to be replaced with with concrete class:

val rowId = FeatureBuilder.Integral[BostonHouse].extract(new RowId).asPredictor

object BostonFeatures {
    class IntegralExtract(f: BostonHouse => Int) extends BostonFeatureFunc[Integral] {
        override def apply(v1: BostonHouse): Integral = f(v1).toIntegral
    }
    class RowId extends IntegralExtract(_.rowId)
}

tovbinm · 2019-11-14T19:27:20Z

@vpatryshev any progress on this one? thanks!

vpatryshev · 2019-11-15T02:31:54Z

Oh, did not even touch. I keep it on my mind all the time, though. Thanks, -Vlad

FYI. Working on it now.

vpatryshev · 2020-01-18T04:27:55Z

@shoafj7917, can you please check that you can reproduce this with the latest version of TransmogrifAI? What you write is not runnable on the current version, and I don't see how to reproduce this behavior. Which directory do you run it in?

jeesim2 · 2020-01-25T07:25:51Z

When I tried with version 0.6.1, failed as the same manner with @shoafj7917.

@vpatryshev . latest version of TransmogrifAI mean master branch?

master branch fails with follow error.

short,

The master version was not published yet, but you can do it locally.

$ git clone git@github.com:salesforce/TransmogrifAI.git
$ cd TransmogrifAI
$ ./gradlew publishToMavenLocal

Even after install master branch to local maven repository then add mavenLocal() to generated bootstrap project's build.gradle file, Bootstrap Project training still fails as follow,
