Issue Description

I am trying to Run a basic Deeplearking4j example, and building a similar version of the famous HotDog or not example. I am running the example on Google colab using jbang and IJava on GPU. Trying to run the code return an exception:

java.lang.NoClassDefFoundError: Could not initialize class org.bytedeco.javacv.OpenCVFrameConverter$ToMat
	at org.datavec.image.loader.NativeImageLoader.<init>(NativeImageLoader.java:59)
	at org.datavec.image.loader.NativeImageLoader.<init>(NativeImageLoader.java:116)
	at org.datavec.image.recordreader.BaseImageRecordReader.initialize(BaseImageRecordReader.java:131)
	at .(#245:1)

Hereis the link to the colab https://colab.research.google.com/drive/1m8BBTgkNMyfAnm4RaqTBERaht5qnNZ5D?usp=sharing
The same code works perfectly if I try to run it locally. Not sure If I missed some sort of dependency ?
