Compatibility Issues

[davibarreira]

I was trying to install version 0.3.9 of our package, and I'm getting compatibility issues with UMAP.jl. Here is the error message:

(@v1.6) pkg> add UMAP

Do any of you guys knows a way around this? I'm doing some work where I need to use both UMAP.jl and OptimalTransport.jl.

It's explained at the bottom of the message: the problem is that LsqFit is not compatible with Distributions 0.25. It should be added to https://github.com/JuliaNLSolvers/LsqFit.jl/blob/2d3611f0e7bd506daf423f15c3e78e3feddd7fb0/Project.toml#L15.

What about making OptimalTransport.jl compatible with 0.24? I think we set the compat to "0.25", but I don't remember if we indeed needed the latest version.

[devmotion]

I think 0.24 should work as well but it would be good to check if tests pass with 0.24.0 locally once before adding it to the compat section.

[davibarreira]

Thanks. It indeed works. I tested and submitted a PR.

[devmotion]

It should work with the latest release of OptimalTransport. However, one should really fix LsqFit.
