Issue with running dl4j-examples #547

Closed redlight55 closed 7 years ago

redlight55 commented 7 years ago

Hi, I'm having a problem with running the dl4j-examples. I followed thoroughly based on the Quick Start Guide itself but to no avail. I also have used the YouTube videos itself which I still can't run it. Trying to test the first example (MLP Linear Classifier) but getting some errors which are shown below.

Do note that I have never tried using Maven before, only IntelliJ. My purpose is to build an AI that works on Android so DL4J is the best library I've found so far but I need to test different types of AI to see which one is the best. I saw that I need the examples to work before I can even start using the library. I really need help. Please and thank you.

@redlight55 somehow you've changed versions or are trying to run cuda. We have an android page here: http://deeplearning4j.org/android From the looks of it, you're trying to run cuda without cuda installed?

redlight55 commented 7 years ago

I've already seen the android section which is why dl4j fits my project. I'm trying to test different types of ANN before I start using it on android. From what I can tell, the android library is understandable. I just want to run examples first. Trying to build a simple ANN and CovNet. Quick question, is the dl4j-examples supposed to have multiple different main folders? Is it that I'm running something that requires something else?

@redlight55 There are intentionallly a bunch of different modules, for different types of examples (datavec, DL4J, cuda-specific DL4J examples, RL4J, Spark etc)

redlight55 commented 7 years ago

I found my issue when trying to run the MLP Linear Classification. I didn't select the example folder inside but instead loaded the whole folder where it had all the datavec, DL4J, etc.

Previously: GitHub/dl4j-examples

Now: GitHub/dl4j-examples/dl4j-examples

I had to be specific on importing the folders. Thank you for all the help. Cheers.
