利用python生成txt文件後,就可以利用caffe自帶工具將圖片轉換爲lmdb格式,其代碼如下
#!/usr/bin/env sh
# Create the imagenet lmdb inputs
# N.B. set the path to the imagenet train + val data dirs
set -e

VAL_DATA_ROOT=/home/yh/caffe/examples/H-W/val/
# Set RESIZE=true to resize the images to 256x256. Leave as false if images have
# already been resized using another tool.
RESIZE=true
if $RESIZE; then
RESIZE_HEIGHT=256
