我正在尝试使用Caffe生成LMDB文件来训练我的CNN。
我使用的数据集是斯坦福狗数据集。下载数据集后，我准备了训练数据集和测试数据集。我将配置保存到了train.txt和val.txt文件中。
然后，我尝试通过在控制台上运行以下两个命令来生成LMDB文件：
GLOG_logtostderr=1 /home/bme/caffe/build/tools/convert_imageset \
--resize_height=200 --resize_width=200 --shuffle \
/home/bme/caffe/data/dogs/data/ \
/home/bme/caffe/data/dogs/dogs_data/train.txt \
/home/bme/caffe/examples/dogs/dogs_train_lmdbGLOG_logtostderr=1 /home/bme/caffe/build/tools/convert_imageset \
--resize_height=200 --resize_width=200 --shuffle \
/home/bme/caffe/data/dogs/data/ \
/home/bme/caffe/data/dogs/dogs_data/val.txt \
/home/bme/caffe/examples/dogs/dogs_val_lmdb但是，运行第一个命令时出现了以下错误：

谢谢
回答：
您发布的输出都是关于训练集生成的（它们是相同的）。看起来在17,493张图片中，有12个损坏的文件，Caffe无法找到/打开这些文件。
请检查这些文件是否存在，并且它们没有损坏。
