caffe：检查失败：cv_img.data无法加载

Question

我使用python训练caffe net，但遇到错误：

I0717 11:05:32.177762  8677 solver.cpp:218] Iteration 0 (0 iter/s, 0.178244s/20 iters), loss = 363409
I0717 11:05:32.177825  8677 solver.cpp:237]     Train net output #0: loss = 363409 (* 1 = 363409 loss)
I0717 11:05:32.177922  8677 solver.cpp:237]     Train net output #1: tmpl = 0

I0717 11:05:32.178014  8677 sgd_solver.cpp:105] Iteration 0, lr = 1e-10
E0717 11:05:32.186724  8703 io.cpp:80] Could not open or find file 
F0717 11:05:32.186736  8703 image_data_layer.cpp:129] Check failed: cv_img.data Could not load 
*** Check failure stack trace: ***
Aborted (core dumped)

这是我网的数据层：

layer {
  name: "data"
  type: "ImageData"
  top: "data"
  top: "tmpo"
  image_data_param {
    is_color: false
    source: "/home/muses/fcn-master/mo/train_o.txt"
    batch_size: 1               
    shuffle: false
  }
} 

layer {
  name: "label"
  type: "ImageData"
  top: "label"
  top: "tmpl"
  image_data_param {
    is_color: false
    source: "/home/muses/fcn-master/mo/train_l.txt"
    batch_size: 1               
    shuffle: false
  }
}  

train_l.txt：（train_o.txt与该文件大致相同）

/home/muses/fcn-master/data/vessel/train/label/13.png 0

我检查了文件路径是否正确。所有文件均在ubuntu14.04下编辑。 然后我修改了io.cpp的第80行，尝试打印错误的文件名，如下所示：

if (!cv_img_origin.data) {
    LOG(INFO) << "FILENAME: " << filename;
    LOG(INFO) << "cv_read_flag: " << cv_read_flag;
    LOG(ERROR) << "Could not open or find file " << filename;
    return cv_img_origin;
  }

错误是：

I0718 10:17:13.220021 18611 io.cpp:80] FILENAME: 
I0718 10:17:13.220058 18611 io.cpp:81] cv_read_flag: 0
E0718 10:17:13.220062 18611 io.cpp:82] Could not open or find file 
F0718 10:17:13.220067 18611 image_data_layer.cpp:129] Check failed: cv_img.data Could not load 

我不知道为什么会出现错误。 如果您知道原因，则非常感谢。

Answer 1

您使文件可执行吗？ 我这样做后问题解决了。

您可以在图像文件夹中使用chmod +x *.jpg或chmod +x *.png来使文件可执行。

Answer 2

我遇到了同样的问题-因为在“无法打开或查找文件”之后没有显示文件名，这意味着您当时正在调用的火车或测试.txt文件中有一个空行 （我是最后一行）的文件）。
