DimensionMismatch("new array has 225 color channels, must have 3")

[lagefreitas]

hello,

I tried to run the notebook in Julia 0.6.3 in OSX and I get the following error at the last cell (#Demo: Style transfer. [...]):

INFO: Recompiling stale cache file /Users/alage/.julia/lib/v0.6/QuartzImageIO.ji for module QuartzImageIO.
DimensionMismatch("new array has 225 color channels, must have 3")
