Hi @jlian2, I've been playing around with the code in the repo as well. * I've also observed negative `loss` values. Since the `loss` is the negative log-likelihood, in fact...
Did you try this: `pip install -U git+https://github.com/google/jax-cfd.git`? I think that the spectral module is not in a released version (yet). Hope this helps!
Yikes sorry for this very very long delay. Did you wind up finding a solution? It may be because the package on PyPI is out of date. @juliandwain
Seems to be a problem with the URL. The following also gives 403: Forbidden. ``` wget "https://storage.googleapis.com/copt/datasets/gisette.tar.gz" ```
Yes, interesting. I'll check it out! Sorry, somehow I missed that I was tagged in this issue! Feel free to assign to me.
I tried to fix this in https://github.com/openopt/copt/pull/34. I think it's the cumulative sum, see https://github.com/openopt/copt/blob/master/examples/frank_wolfe/plot_vertex_overlap.py#L56
I should add some unit tests for this as well, but I thought that now might be a good time to get feedback. I can convert this to a github...
Note to self: are there places where I could make the code faster? Specifically, but using numba / utils.njit? There aren't any tight loops where I am going over an...
Super, thanks you! I'll do these things and update.
Rather than this clumsy `use_eigs` option that was there before, I replaced it with a new lmo, TraceSpectrahedron, which optimizes over the psd matrices with bounded trace norm. This is...
