Unable to choose layer specification through UI #38

Closed sarda014 closed 6 years ago

sarda014 commented 6 years ago

I have installed wekaDeeplearning4j package using the package manager, but I am not able to choose different type of layers for network.

Steps to reproduce -

Weka version: 3.8.2 wekaDeeplearning4j package version: 1.5.6 Operating System: macOS

eibe commented 6 years ago

This works fine for me using macOS with Oracle Java. Details below. I’m using WEKA 3.9.4-SNAPSHOT, but there should be no difference regarding this to 3.8.3 or 3.9.3. Note that I have not installed the GPU set-up because my Mac has an AMD GPU.

Sorry, I take that back. It does NOT work for me either. Moreover, the same problem occurs on Linux, regardless of whether GPU or GPU support is used!

Dl4jMlpClassifier appears to work fine from the CLI though. I tried

java weka.Run .Dl4jMlpClassifier -layer ".DenseLayer -nOut 10" -layer ".OutputLayer" -t ~/datasets/UCI/iris.arff

and it works fine on both macOS and Linux.

Perhaps there is an issue with serialisation?

Thanks for double-checking Eibe! I can have a look at it next week at the earliest.

@sarda084 is that the only exception that is thrown? Can you copy the whole stacktrace to hastebin.com or something else and post it here? I'm confused about the fact that the ND4J backend "could not be found". This error occurred once in the past but should've been solved.

sarda014 commented 6 years ago

Sure, you can find the entire stacktrace here - https://hastebin.com/juxipefobu.nginx

The hotfix will be released with v1.5.7 soon
