caffe 模型中的裁剪大小错误

Question

我正在尝试训练咖啡 Model.I 收到此错误

我遇到了类似的错误，但是 Check failed: height<=datum_height (227 vs. 224)。然后我将 227 更改为 224，但现在我得到了 this.Any 个建议？

编辑：我的 LMDB 代码-

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
fi

 echo "Creating data lmdb..."
 GLOG_logtostderr=1 $TOOLS/convert_imageset \
    $DATA_ROOT \
    $DATA/train.txt \
    $EXAMPLE/train_lmdb

echo "Done."

这是我用来创建 LMDB 文件的代码- 这是我用来创建 LMDB 文件的代码-

Answer 1

输入数据集中的一张（或多张？）图像似乎有 height = 199。Caffe 无法将高度为 199 的图像裁剪为 224 大小。

错误消息解释：

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

查看 'data_transformer.cpp' line 168:

CHECK_LE(height, datum_height);

数据转换器检查作物高度 (height) 是否小于或等于 (LE) 输入 datum_height。
从错误消息中可以看出，此检查失败，这意味着输入高度大于裁剪高度。条件 height=224 <= datum_height=199 不成立并引发错误。
