caffe模型中的作物大小错误 [英] Crop size Error in caffe Model

问题描述

我正在尝试训练caffe模型.出现此错误

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

我遇到了类似的错误，但Check failed: height<=datum_height (227 vs. 224).然后我将227更改为224，但是现在我明白了.有什么建议吗?

我的LMDB代码-

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

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."

解决方案

输入数据集中的一个(或多个?)图像似乎具有height =199.Caffe无法将高度199的图像裁剪为224尺寸. /p>

错误消息说明:

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);

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

I was getting a similar error but Check failed: height<=datum_height (227 vs. 224) .I then changed 227 to 224 ,but now i get this.Any suggestions?

EDIT:My code for LMDB-

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

This is the code i used to create the LMDB files- This is the code i used to create the LMDB files-

解决方案

It seems like one (or more?) images in your input dataset has height = 199. Caffe cannot crop image with height 199 to size 224.

Error message explained:

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

Looking at the 'data_transformer.cpp' line 168:

CHECK_LE(height, datum_height);

the data transformer checks that the crop height (height) is less than or equal (LE) to the input datum_height.
As you can see from the error message, this check failed, meaning input height is larger than the crop height. The condition height=224 <= datum_height=199 does not hold and an error is raised.
