Description
Describe the bug
I am new to SPTAG and trying to run the "Tutorial" notebook but ran into below segmentation error while running quantizer. Appreciate your help on this.
Environment - Docker on Ubuntu
To Reproduce
Steps to reproduce the behavior:
- Create docker image with docker file. Had to use forked branch
https://github.com/pabs3/SPTAG/tree/install-to-python-modules-dirfrom @pabs3 due to build errors on this repo - Bring up docker container and start the notebook and sptag
- Run the
Tutorialnotebook on docs folder of this repo - See error
Error
CompletedProcess(args='/usr/local/bin/quantizer -d 100 -v Float -f DEFAULT -i /mnt/sptag_index/vectors.bin -o quan_doc_vectors.bin -oq quantizer.bin -qt PQQuantizer -qd 50 -ts 1000 -norm false', returncode=139)

Research direction
Start by reproducing the failure from the Tutorial notebook in the docs folder using the reported Docker-on-Ubuntu setup and the shown quantizer command. Check the command's inputs and output paths while narrowing down the segmentation fault; done means the notebook's quantizer step completes without return code 139.
