Hi,  
I am working through Tanmay Bakshi’s lovely book and get errors  
when it gets really interesting (in the Machine Learning chapter).

I have Julia 1.3 on a mac, with Flux downgraded to 0.9 to have  
the Metalhead compatibility. See also  
[https://discourse.julialang.org/t/julia-1-3-and-metalhead/3245](https://discourse.julialang.org/t/julia-1-3-and-metalhead/3245)  
and the kind help from @ Syx\_Pek

Here is the code I am trying to run:

```julia
using Metalhead: VGG19, preprocess, load, labels
using Flux: onecold

model = VGG19()
class_labels=labels(model)

print("Enter the name of your file: ")
user_image = preprocess(load(readline()))

model_prediction = model(user_image)
top_class = onecold(model_prediction)[1]
class_name = labels[top_class]

println("I think this image contains: $(class_name)")

```

(This is from pages 150-151 in the book.)  
And here is the errors I get:

```julia

Enter the name of your file: test.jpg
ERROR: LoadError: MethodError: no method matching labels(::Int64)

```

**Added:** I tried this also on CoCalc and it does not work there either.  
Sadly, it does not even work on the PAID version of Juliabox - as the kernel keeps restarting…

Any help would be awesome!
