Latest version returns server error: "All arrays must have same shape except the axis to concatenate"

I'm updating https://github.com/liamjones/PaintsChainer-Docker to pick up recent changes and I'm getting processing errors.

I've bisected the new commits and it seems like something broke in commit e240af8 (looks like this commit is related to issue #53? Thanks for looking at it :+1:).

Oh it seems to be a bug... sorry

[taizan]

I think it is fixed

[liamjones]

It is, thank you! :smile:
