Change stride number in detection_data_param causing error

[JingyaLiu]

While I change the stride number from 16 to 4 at detection_data_param and causing for following error, do you have any suggestions?

For train.prototxt:
detection_data_param {
root_folder: "/media/tensor-server/MedicalImage/LUNA16/"
source: "../../../data/LUNA16/window_file_LUNA16_trainval.txt"
batch_size: 1
short_size: 700
long_size: 1000
stride: 4
