Hi All
I am training Tesseract for Perso-Arabic languages using my custom dataset.
I get *Segmentation fault-core dumped* error and training gets stopped.
Net-spec used: net_spec '[1,0,0,1 Ct5,5,16 Ct3,3,8 Mp3,3 Lfys64 Lfx128
Lbx64 Lby64 Lrx128 Lfx128 O1c105]'.Attaching the terminal error output
below:
Thread 1 "lstmtraining" received signal SIGSEGV, Segmentation fault.

Any help to solve this shall be highly appreciated.
