            The exceptions that you listed do not affect the script execution, as they get handled internally by pww3 (error output could not be suppressed, unfortunately, despite catching the exceptions; this gets output by the underlying javabridge library).

            A bit of background: Since pww3 can run with and without package support, it first tries to load classes using the Java classloader. If that fails (that's the error message that you see), it will try loading them using Weka's mechanism for loading classes.

            The just released version 0.2.7 of pww3 approaches this a bit more intelligent and avoids the output of these exceptions.

            Final note: you need to drop the classifier. prefix in your property names when using MultiSearch.

            Answered 2021-Aug-26 at 06:34

            The answer (see GitHub discussion) is that this error message is simply false.

            To avoid this error, the model's local filename (usually for the form model_filename.tar.gz) must be used, not the model name.

            The documentation does say this, though it lacks essential detail.

            I found this to be the best example. See the last part of that Notebook, in which invoke_endpoint is used (rather than a predictor as used earlier in the Notebook).

            As to the location of that model file: This Notebook says:

            When creating the Model entity for multi-model endpoints, the container's ModelDataUrl is the S3 prefix where the model artifacts that are invokable by the endpoint are located. The rest of the S3 path will be specified when invoking the model.

            Hard to guess from your code, but with a little bit of debugging you might figure it out. Try to console.log what exactly image.sampleRegions is and what are the properties of image object. From there you might be able to see what's wrong - undefined property, wrong type, etc.

            Issue/Bug when loading and applying MultilayerPerceptronClassifier in Spark Version 3.0.0

            Why does this ConcurrentHashMap stream only run half of entries at a time?
            Asked 2020-Jul-04 at 13:41

            I'm mystified by this curiosity. (I'm using ConcurrentHashMap rather than ConcurrentSkipListSet because the class doesn't implement Comparable.) I've got plenty of free CPUs on the computer and there is no difference between the classes that are run in the stream (other than random number generation). It's suspicious that the even numbers run first (consistently).

            Here are the code and output with nRuns=10. I would expect all 10 threads to fire up and run simultaneously (as they usually do in my other uses of ConcurrentHashMap). Could it be due to some static code in LIBSVM that gets called by SvmCrossValidator? That's all I can think of. It seems to me from a basic Java perspective this stream should launch all 10 processes at once.
