[PowerGraph] Segmentation fault: 11 on simple ALS demo

User 2689 | 11/29/2015, 9:00:10 PM

Hi, I just follow the tutorial and try to run graphlab ALS on my own laptop. Mac OS X Yosemite 10.10.3.

cd graphlab/release/toolkits/collaborativefiltering/ mkdir smallnetflix cd smallnetflix/ wget http://www.select.cs.cmu.edu/code/graphlab/datasets/smallnetflixmm.train wget http://www.select.cs.cmu.edu/code/graphlab/datasets/smallnetflix_mm.validate cd ..

./als --matrix ./smallnetflix/ --maxiter=5 --ncpus=1 --predictions=outfile

Then, I get the Segmentation fault: 11. Could someone help me solve this problem?

Never mind. This post solves my problem. ./configure --notcmalloc --nompi

Hi Please note we have a way better ALS implementation here: as part of our GraphLab Create offering.
