when i change the number of train pictures,I got error

[zcx9112040]

At first i put 1000 photos in data/train ,then i run "python train_nn.py --cnf configs/c_128_5x5_32.py",there is nothing wrong, but when i put 35000 photos in data/train, i got error, I sure i have changed the labels too,failed as this:

what should i do? can you give me some advice?
