从具有两个不同类的自己的数据集正确创建了train.txt和val.txt之后，我在里面创建了带有data.mdb（67.7Mb），lock.mdb（8.2kB）和mean.binaryproto（786.4kB）的train_leveldb ，以及带有data.mdb（16.9Mb），lock.mdb（8.2kB）和mean.binaryproto（786.4kB）的val_leveldb。
在那之后，我开始如下训练网络：
>/opt/movidius/caffe/build/tools/caffe train --solver=/opt/movidius/caffe/models/bvlc_reference_caffenet/solver_isia.prototxt --weights /opt/movidius/caffe/models/bvlc_reference_caffenet/bvlc.caffemodel 2>&1 | tee /opt/movidius/caffe/models/blvc_reference_caffenet/train.log
MDB数据库文件（train和val）存在并且可以访问，也都意味着.binaryproto。有解决的办法吗？任何评论都将受到欢迎。
谢谢。
