caffe模型中的作物尺寸误差

Question

我试着训练一个caffe模型，我知道这个错误

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

我得到了一个类似的错误，但是Check failed: height<=datum_height (227 vs. 224) .I后来将227更改为224，但现在我得到了this.Any的建议？

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

# ------------------------------
# Creating LMDB
 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-

看上去像是一个(或更多？)输入数据集中的图像具有height = 199。Caffe不能裁剪高度199到224大小的图像。

错误信息解释如下：

data_transformer.cpp:168]检查失败: height<=datum_height (224对199)

看着 line 168

CHECK_LE(height, datum_height);

数据转换器检查作物高度(height)是否小于或等于输入datum_height。

从错误消息中可以看到，此检查失败，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。
