On first using.

Hm. Same here.

If I get it right, TrackedArray came from Flux. Yet it doesn't appear in the Flux documentation anymore starting with version 0.10.

[devonjkohler]

I had the same problem. Was able to solve it by first installing Flux version 0.9 and then installing Omega.

[zenna]

Thanks, I'll fix this shortly. I'm working on a rewrite of Omega which is why this repo is a bit stagnant. Stay tuned!

It might be advantageous to write this in the documentation. I have trouble installing Omega.jl

The dependencies to Flux, CUDA and Omega might be documented
