freebase download failure

[guihaomin]

I tried to do the ./pull-dependencies fullfreebase-vdb in the tutorial. However the script segmentation fault at the last %1....

• Could you try removing lib/fb_data/ and rerunning the command?
• Could you check if there is enough space? The file is very large (30GB total).

I figure out the problem is a wget bug in version 1.19.1. I downloaded and compiled/install wget 1.91.4 and that solved the issue.

May I ask if this freebase for WebQuestions or SimpleQuestions? Or it's just a subset for fun?

Here are the stats for the freebase vdb

It should be the complete KB needed for WebQuestions.

We didn't have involvement with SimpleQuestions. You can download the subset of Freebased needed for SimpleQuestions on the Facebook Research webpage

Thank you for the reply!
I noticed that different researchers may use different freebase subset for research.
Recently I tried to use this freebase to evaluate another work, but failed to get satisfying result. The main reason is that, candidate entity mids offered by him cannot be found in this freebase.
He may used a different subset. This might be a painful point for many KBQA researchers.

Thank you again! Really learning a lot from this repo!
