cupy.cuda.curand.CURANDError.__init__ (cupy/cuda/curand.cpp:1108)

I just enter:
CHAINER_TYPE_CHECK=0 CHAINER_SEED=$1 nohup python scripts/train.py --seed 0 --gpu 0 --model models/MnihCNN_multi.py --train_ortho_db data/mass_merged/lmdb/train_sat --train_label_db data/mass_merged/lmdb/train_map --valid_ortho_db data/mass_merged/lmdb/valid_sat --valid_label_db data/mass_merged/lmdb/valid_map --dataset_size 1.0 > mnih_multi.log 2>&1 < /dev/null &
and this is the log:
