Segment fault

[seawindow]

Hello, I am running your code ：th main.lua -dataset myTrain -learningRate 0.01 -momentum 0.9 -string first-run -device 1 -top_rand -batchSize 2 -saveModel (modified the address in main.lua and used your data) and a segmentation error has occurred. I haven't solved this problem for a long time after debugging. The main mistakes are these three:
[1][475221.681741] python[35692]: segfault at 20 ip 00007ff51a25a760 sp 00007ffe58687d00 error 4 in python3.7[7ff51a179000+1e1000];
[2][544549.003939] a.out[24933]: segfault at 6023e0 ip 0000000000401600 sp 00007ffd7fad55a0 error 7 in a.out[400000+3000];
[3][992757.284087] luajit[50534]: segfault at 18 ip 00000000004687d3 sp 00007ffd37779388 error 4 in luajit[400000+99000].I want to know if there is a problem with my environment or the way to run the code.Thank you!
