I get an error message related to CuArrays when I import Flux

```julia
julia> using Flux
[ Info: CuArrays.jl failed to initialize and will be unavailable (set JULIA_CUDA_SILENT or JULIA_CUDA_VERBOSE to silence or expand this message)

julia> net = Dense(4,1)
Dense(4, 1)

julia> net = gpu(net)
Dense(4, 1)

julia> net.W
1×4 Array{Float32,2}:
 0.854675 -0.099462 0.313961 0.352113

```

I use Julia 1.3.0, Flux 0.10 and CuArrays 1.5.0. Everything is up to date.

Yes the GPU ecosystem has been undergoing stabilisation.  
As the error message says set the environment flag `JULIA_CUDA_VERBOSE=1` to check why it was unable to initialize GPU support.

I opened an issue about it. [https://github.com/FluxML/Flux.jl/issues/949](https://github.com/FluxML/Flux.jl/issues/949)
