Question

我正在尝试使用caffe训练网络，但是我收到了一个未找到文件的例外：

I0111 11:19:27.339706  5151 layer_factory.hpp:76] Creating layer data
I0111 11:19:27.340117  5151 net.cpp:106] Creating Layer data

Aborted (core dumped)

可能存在导致错误的各种事情，但这个特定文件似乎确实存在。我已经将路径更改为绝对路径，检查拼写（在这个确切的文件夹中确实存在具有此确切名称的文件）并双重检查要读写的文件的权限。
当文件似乎存在时，难以找到此错误的原因。我的意思是，还有什么可能的原因？
所以我的问题是：有谁知道这个错误的原因是什么？

编辑：根据要求，输出ls -ltrh /home/myUser/Documents/code/RFNN/data/ILSVRC2012/10class/imagenet_mean_10biggest.binaryproto：

-rwxrwxr-x 1 myUser myUser 769K jan 10 16:39 /home/myUser/Documents/code/RFNN/data/ILSVRC2012/10class/imagenet_mean_10biggest.binaryproto

我假设原型文件的相关部分是：

name: "rfnn_ILSVRC2012_Small"
layer {
top: "data"
top: "label"
name: "data"
type: "Data"
data_param {
source: "/home/myUser/Documents/code/RFNN/data/ILSVRC2012/10class/ilsvrc12_train_lmdb_10biggest"
backend: LMDB
batch_size: 32
}
transform_param {
crop_size: 224
mirror: true
mean_file: "/home/myUser/Documents/code/RFNN/data/ILSVRC2012/10class

/imagenet_mean_10biggest.binaryproto"
  }
  include: { phase: TRAIN }
}
layer {
  top: "data"
  top: "label"
  name: "data"
  type: "Data"
  data_param {
    source: "/home/myUser/Documents/code/RFNN/data/ILSVRC2012/10class/ilsvrc12_val_lmdb_10biggest"
    backend: LMDB
    batch_size: 32
  }
  transform_param {
    crop_size: 224
    mirror: false
    mean_file: "/home/myUser/Documents/code/RFNN/data/ILSVRC2012/10class/imagenet_mean_10biggest.binaryproto"
  }
  include: { phase: TEST }
}

你的卑鄙文件确实存在，但这不是caffe抱怨的你的数据库文件'/home/myUser/Documents/code/RFNN/data/ILSVRC2012/10class/ilsvrc12_train_lmdb_10biggest'怎么样？它在正确的位置吗？

No such file or directory只能表示有No such file or directory吗？

是

“没有这样的文件或目录”只能意味着“没有这样的文件或目录”吗？
