Segmentation error (core dumped)

[Shuan Chen]

I tried to reproduce the result of USPTO-50K, however I ran into the Segmentation error like this:

python bin/eval.py models/uspto_50k --beam-size 50 --show-every 100

How can I solve this problem?

I found that this is about the maximum stack issue.
It can be solved by the following command (found in https://stackoverflow.com/questions/10035541/what-causes-a-python-segmentation-fault)

export OPENBLAS_NUM_THREADS=1 
export OPENBLAS_MAIN_FREE=1

and it works.
