examples/wzy/create_meanfile.sh: 行 5: 17469 已放棄               (核心已轉儲) $TOOLS/compute_image_mean $EXAMPLE/ilsvrc12_train_lmdb $DATA/imagenet_mean.binaryproto
Done.
 

其中create_meanfile.sh內容為：

EXAMPLE=examples/wzy
DATA=examples/wzy
TOOLS=build/tools

$TOOLS/compute_image_mean $EXAMPLE/ilsvrc12_train_lmdb $DATA/imagenet_mean.binaryproto

echo "Done."

原因是create_wzynet.sh中

$EXAMPLE/ilsvrc12_train_lmdb   

導致建立的ilsvrc12_train_lmdb 目錄後面也有空格，因此執行create_meanfile.sh時就找不到這個目錄了

create_wzynet.sh內容：

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

TRAIN_DATA_ROOT=/
VAL_DATA_ROOT=/

# 這裡我們開啟resize，需要把所有圖片尺寸統一
RESIZE=true
if $RESIZE; then
  RESIZE_HEIGHT=256
  RESIZE_WIDTH=256
else
  RESIZE_HEIGHT=0
  RESIZE_WIDTH=0
fi

.......

echo "Creating train lmdb..."
