caffe模型中的作物大小錯誤

Question

我正在嘗試訓練Caffe Model。我收到此錯誤

I0806 09:41:02.010442  2992 sgd_solver.cpp:105] Iteration 360, lr = 9.76e-  05

我遇到了類似的錯誤，但Check failed: height<=datum_height (227 vs. 224) 。然后將227更改為224，但是現在我明白了。有什么建議嗎？

編輯：我的LMDB-代碼

EXAMPLE=/home/hyperworks/colorfile/   # Path where the output LMDB is stored
DATA=/home/hyperworks/colorfile/      # Path where the data.txt file is present 
TOOLS=/home/hyperworks/caffe/build/tools/   # Caffe dependency to access the convert_imageset utility 
DATA_ROOT=/home/hyperworks/colorfile/train/ # Path prefix for each entry in data.txt
# +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

# ----------------------------

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

# Checks for DATA_ROOT Path
if [ ! -d "$DATA_ROOT" ]; then
  echo "Error: DATA_ROOT is not a path to a directory: $DATA_ROOT"
  echo "Set the DATA_ROOT variable to the path where the data 
   instances are stored."
  exit 1

echo "Done."

這是我用來創建LMDB文件的代碼-這是我用來創建LMDB文件的代碼-

輸入數據集中的一幅（或多幅？）圖像似乎具有height =199。Caffe無法將高度199的圖像裁剪為尺寸224。

錯誤消息說明：

 data_transformer.cpp:168] Check failed: height<=datum_height (224 vs. 199) 

查看'data_transformer.cpp'第168行 ：

CHECK_LE(height, datum_height);

數據轉換器檢查作物高度（ height ）是否小於或等於輸入數據datum_height （LE）。
從錯誤消息中可以看到，該檢查失敗，這意味着輸入高度大於裁切高度。 條件height=224 <= datum_height=199不成立，並引發錯誤。
