Does ensmallen work with armadillo >=10.0?

[DManowitz]

The ensmallen (and mlpack) package on conda-forge indicates that this package will not work with armadillo >=10.0. However, the ensmallen.org home page states that armadillo >=9.800 will work. Which is correct?

[rcurtin]

That's strange, I use both libraries regularly with newer Armadillo versions and it works fine. (The CI build jobs often use newer versions too.) So I think there must be an error in the conda-forge packages.

it is probably an error

@DManowitz I'm not seeing an upper limit on the anaconda page for the packages:

• https://anaconda.org/conda-forge/mlpack
• https://anaconda.org/conda-forge/ensmallen

By the looks of the recipes, we're requiring:

MLPACK

    - armadillo >=9.800.0
    - ensmallen >=2.10.0

https://github.com/conda-forge/mlpack-feedstock/blob/e5ceee9a5772b2c0c0239986d13db950b20561b4/recipe/meta.yaml#L32-L45

Ensmallen

    - armadillo >=8.400.0

https://github.com/conda-forge/ensmallen-feedstock/blob/5292318a0dd9f39f2ed1e62c5e068d12ee1716cc/recipe/meta.yaml#L22

Could you please provide a screenshot or step to reproduce where you are seeing an upper bound?

[DManowitz]

I agree that the recipes don't have an upper limit , but when I look at the most recent packages using conda search, I see the following:

@DManowitz thanks! This looks like we're running into issues because the underlying feeds need to be boosted to the new versions.
