caffe：检查失败：cv_img.data 无法加载

Question

我使用python训练caffe net但是遇到错误：

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

*** Check failure stack trace: ***
Aborted (core dumped)

这是我的网络的数据层：

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与本文件大致相同)

我检查过文件路径是correct.All文件是在ubuntu14.04下编辑的。然后我修改了io.cpp的第80行，尝试像这样打印错误的文件名：

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;
  }

错误来了：

I0718 10:17:13.220021 18611 io.cpp:80] FILENAME: 
I0718 10:17:13.220058 18611 io.cpp:81] cv_read_flag: 0

F0718 10:17:13.220067 18611 image_data_layer.cpp:129] Check failed: cv_img.data Could not load

我不明白为什么会出现错误。知道原因的，万分感谢

Answer 1

您是否使文件可执行？我这样做之后我的问题就解决了。

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

我有同样的问题 - 因为在 "Could not open or find file" 之后没有显示文件名，这意味着你在火车或测试 .txt 中有一个空行你当时正在打电话（我的是文件的最后一行）。
