如何为咖啡输入准备灰度图像数据

Question

我已经阅读了大量的咖啡输入准备图像数据的参考资料，但尚未能解决我的问题！

我已经把.jpg图像文件在2个独立的文件夹：

folder train: containing 100,000 image files of size 227*227 
folder val: containing 9,000 image files of size 227*227 

我把它们放在一个文件夹中/home/user/DL

然后我train和val了两个文本文件列出图像的名称文件夹为：

. 
. 
p127.jpg 2 
p943.jpg 2 
p8765.jpg 1 
. 
. 

，我把这两个文件/home/user/caffe-master/data/DL。

我做了位于DL_create.sh在/home/user/caffe-master/examples/DL波纹管：

set -e 

EXAMPLE=examples/DL 
DATA=data/DL 
TOOLS=build/tools 

TRAIN_DATA_ROOT=/home/user/DL/train/ 
VAL_DATA_ROOT=/home/user/DL/val/ 


RESIZE=true 
if $RESIZE; then 
    RESIZE_HEIGHT=227 
    RESIZE_WIDTH=227 
else 
    RESIZE_HEIGHT=0 
    RESIZE_WIDTH=0 
fi 

if [ ! -d "$TRAIN_DATA_ROOT" ]; then 
    echo "Error: TRAIN_DATA_ROOT is not a path to a directory: $TRAIN_DATA_ROOT" 
    echo "Set the TRAIN_DATA_ROOT variable in create_DL.sh to the path" \ 
     "where the DL training data is stored." 
    exit 1 
fi 

if [ ! -d "$VAL_DATA_ROOT" ]; then 
    echo "Error: VAL_DATA_ROOT is not a path to a directory: $VAL_DATA_ROOT" 
    echo "Set the VAL_DATA_ROOT variable in create_DL.sh to the path" \ 
     "where the DL validation data is stored." 
    exit 1 
fi 

echo "Creating train lmdb..." 

GLOG_logtostderr=1 $TOOLS/convert_imageset \ 
    --resize_height=$RESIZE_HEIGHT \ 
    --resize_width=$RESIZE_WIDTH \ 
    --shuffle \ 
    --gray \ 
    $TRAIN_DATA_ROOT \ 
    $DATA/train.txt \ 
    $EXAMPLE/DL_train_lmdb 

echo "Creating val lmdb..." 

GLOG_logtostderr=1 $TOOLS/convert_imageset \ 
    --resize_height=$RESIZE_HEIGHT \ 
    --resize_width=$RESIZE_WIDTH \ 
    --shuffle \ 
    --gray \ 
    $VAL_DATA_ROOT \ 
    $DATA/val.txt \ 
    $EXAMPLE/DL_val_lmdb 

echo "Done." 

然后当我运行DL_create.sh脚本来改变我的图像数据转换成lmdb它无法找到我的图像，并给出了类似的消息：

可否请你帮我知道我在做什么错误??！？！

问题是我有的图像是uint16位图！但是，经过大量搜索后，我发现caffe在uint8位图上工作
