I followed the guide and I trained on a subset of ucf-101 dataset. I used 3 classes (I changed the num_output of last fc to 3) and it works. I have a strange problem when I use the script /build/tools/extract_image_features.bin. If I use it in demo it works (in c3d_feature_extraction folder), but if I use it with my training it doesn't work. \r\nI use the .prototxt in c3d_train_ucf101 and the snapshot created in the training. \r\nThe script is this one:\r\n```GLOG_logtosterr=1 ../../build/tools/extract_image_features.bin ./proto_files/conv3d_ucf101_test_nobias.prototxt ./snapshots/conv3d_ucf101_3classes_titan_nobias_iter_450 0 1 1 ./proto_files/output_list_prefix.txt prob```\r\n\r\nI have the following error:\r\nI1217 18:49:40.410287 23534 net.cpp:76] Creating Layer fc8\r\nI1217 18:49:40.410292 23534 net.cpp:86] fc8 <- fc7\r\nI1217 18:49:40.410297 23534 net.cpp:112] fc8 -> fc8\r\nI1217 18:49:40.410418 23534 net.cpp:127] Top shape: 1 3 1 1 1 (3)\r\nI1217 18:49:40.410436 23534 net.cpp:154] fc8 needs backward computation.\r\nI1217 18:49:40.410444 23534 net.cpp:76] Creating Layer prob\r\nI1217 18:49:40.410449 23534 net.cpp:86] prob <- fc8\r\nI1217 18:49:40.410459 23534 net.cpp:112] prob -> prob\r\nI1217 18:49:40.410466 23534 net.cpp:127] Top shape: 1 3 1 1 1 (3)\r\nI1217 18:49:40.410471 23534 net.cpp:154] prob needs backward computation.\r\nI1217 18:49:40.410477 23534 net.cpp:76] Creating Layer accuracy\r\nI1217 18:49:40.410482 23534 net.cpp:86] accuracy <- prob\r\nI1217 18:49:40.410487 23534 net.cpp:86] accuracy <- label\r\nI1217 18:49:40.410500 23534 net.cpp:112] accuracy -> accuracy\r\nI1217 18:49:40.410524 23534 net.cpp:127] Top shape: 1 2 1 1 1 (2)\r\nI1217 18:49:40.410531 23534 net.cpp:154] accuracy needs backward computation.\r\nI1217 18:49:40.410536 23534 net.cpp:165] This network produces output accuracy\r\nI1217 18:49:40.410553 23534 net.cpp:183] Collecting Learning Rate and Weight Decay.\r\nI1217 18:49:40.410573 23534 net.cpp:176] Network initialization done.\r\nI1217 18:49:40.410578 23534 net.cpp:177] Memory required for Data 103796772\r\n in the network ./proto_files/conv3d_ucf101_test_nobias.prototxt failed: feature_extraction_net->has_blob(string(argv[i])) Unknown feature blob name prob\r\n*** Check failure stack trace: ***\r\nAborted (core dumped)\r\n\r\nAs you can see the layer prob is present.
