I try to run this code: [GPU vs CPU benchmarks with Flux.jl](https://thomaswiemann.com/GPU-vs-CPU-benchmarks-with-Flux.jl)

But executing:

```julia
using Metalhead, Images
using Metalhead: trainimgs

```

fails with:

```julia
julia> using Metalhead: trainimgs
ERROR: UndefVarError: `trainimgs` not defined
Stacktrace:
 [1] top-level scope
   @ ~/.julia/packages/CUDA/is36v/src/initialization.jl:162

```

Any idea?
