我在使用Python训练caffe网络时遇到了一个错误：
I0717 11:05:32.177762 8677 solver.cpp:218] Iteration 0 (0 iter/s, 0.178244s/20 iters), loss = 363409I0717 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 = 0I0717 11:05:32.178000 8677 solver.cpp:237] Train net output #2: tmpo = 0I0717 11:05:32.178014 8677 sgd_solver.cpp:105] Iteration 0, lr = 1e-10E0717 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)这是我的网络的数据层：

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; }错误变成了：

回答：
你是否让文件可执行了？我在做了这个操作后问题就解决了。
你可以在图像文件夹内使用chmod +x *.jpg或chmod +x *.png来使文件可执行。
