Dependencies overwriting methods

[pearlzli]

When I load DoubleFloats, I get some very long warnings about GenericLinearAlgebra (v0.2.4) overwriting GenericSVD (v0.3.0) and GenericSchur (v0.4.0) methods, similar to those on this Discourse post (also me, from a while ago), this GLA issue, and this GSVD issue. DoubleFloats depends on all three:

DoubleFloats -> {GenericSVD, GenericSchur, Polynomials -> GenericLinearAlgebra}

The GLA issue linked above recommends not using both GLA and GSVD at the same time, since GLA already implements a generic SVD. Would it be possible to have DoubleFloats use only GLA?

Polynomials v1.1.13 (released 4 days ago) introduced dependency on GenericLinearAlgebra
JuliaMath/Polynomials.jl#297

Pinning Polynomials v1.1.12 might be a temp workaround.

Thank you for the insight. Considering possibilities ...

I started an attempt to fix this at JuliaLinearAlgebra/GenericLinearAlgebra.jl#71.

super!

Why does this package depend on GenericSVD? Does that mean GenericSVD is just not generic enough?

[JeffreySarnoff]

At the time, LinearAlgebra was not generic enough and GenericSVD did provide svd and friends that worked with DoubleFloats. So it depends on GenericSVD to provide svd. I know there have been changes in LinearAlgebra .. I will check if that now works generically enough to cover DoubleFloats.

[JeffreySarnoff]

@JeffBezanson GenericSVD is necessary to provide svd, svdvals etc.
LinearAlgebra, if it provides generic versions, does not provide generic versions that are generic enough.

maybe all is alright now -- reopen otherwise
