Unable to extract latent factors of low-rank approx: `gd_mf_weights` doesn't compile #1229

Closed KristianHolsheimer closed 7 years ago

KristianHolsheimer commented 7 years ago

Hi there,

I'm trying to train word embeddings using vw's low-rank approximation feature. I noticed the nice wiki page that describes how to extract the latent factors.. exactly what I need.. Awesome!

I tried to compile the gd_mf_weights tool,

$ cd library
$ make gd_mf_weights

but I got the this stack trace.

Note I also noticed that there was another issue with gd_mf_weights some time ago [#933]. I opened a new issue, because the only overlap I could see is that the gd_mf_weights doesn't seem to be maintained at the moment.

Thanks!

Lack of maintenance is definitely the issue here. I'm 'ccing Jake who may have time to look into. I'm superoverloaded for the next several weeks.

Okay, no worries, it would've been really nice. For the time being, I'll just use my own little hack parsing the --audit output.

Thanks John!

JohnLangford commented 7 years ago

Huh, it actually does compile, at least on my machine and travis. Just type 'make all' in the root directory.

Okay, I'll give it another try. Thanks for looking into it
