Failed to build rlemasklib
ERROR: Could not build wheels for rlemasklib, which is required to install

Do you have an idea how that can be fixed? For now I'll stick to older version of the package.

[Jendker]

It was actually very easy, the error is surprisingly well described. Can you have a look at https://github.com/isarandi/rlemasklib/pull/3 ? Thank you.

[isarandi]

Thanks, I'll push some more fixes very soon.

[isarandi]

Fixed.
