Description

From the 60-minute blitz:

using Statistics
using Flux, Flux.Optimise
using Images: channelview
using Metalhead
using Metalhead: trainimgs, valimgs
using Images.ImageCore
using Flux: onehotbatch, onecold, flatten
using Base.Iterators: partition

However, I get the following error: image

So the example is not functional.

Research direction
Investigate if the functions trainimgs and valimgs are still exported from Metalhead. If not, update the 60 minute blitz example to use the correct imports or alternative APIs. Check the model zoo repository for the exact file of the blitz tutorial and any related discussion in the comments for a potential fix.
