                        A potential issue when plotting unet predictions
In the example provided, the last part is slightly not working on my end.  It seems we have to revise the code so that image should be a magick image object:
images <- tibble(
  image = batch[[1]] %>% array_branch(1),
  predicted_mask = predictions[,,,1] %>% array_branch(1),
  mask = batch[[2]][,,,1]  %>% array_branch(1)
) %>% 
  sample_n(2) %>% 
  map_depth(2, function(x) {
    as.raster(x) %>% magick::image_read()
  }) %>% 
  map(~do.call(c, .x))
out <- magick::image_append(c(
  magick::image_append(images$mask, stack = TRUE),
  magick::image_append(images$image, stack = TRUE), 
  magick::image_append(images$predicted_mask, stack = TRUE)
  )
)
plot(out)`
