Use of C3d

1. cd C3D-v1.0
2. cp Makefile.config.example Makefile.config
3. If opencv The version is greater than 3.0 It also needs to be Makefile.config Set according to the prompt in the file
# Uncomment if your OpenCV version >= 3.0
OPENCV_VERSION := 3
4.make -j8
5.“fatal error: hdf5.h: There is no file or directory ” resolvent
Step 1
stay Makefile.config File first 85 That's ok , add to /usr/include/hdf5/serial/ To INCLUDE_DIRS, That is to change the first line of code below into the second line of code .

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/

Step 2
stay Makefile File first 173 That's ok , hold hdf5_hl and hdf5 It is amended as follows hdf5_serial_hl and hdf5_serial, That is to change the first line of code below into the second line of code .

LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_hl hdf5
LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_serial_hl hdf5_serial
6.make clean
7.make -j8
8. First test whether it can run

cd examples/c3d_feature_extraction
sh c3d_sport1m_feature_extraction_frm.sh

Problems encountered ：
9.Check failed: error == cudaSuccess (2 vs. 0)  out of memory
batch_size It's a little bit big , Change a little . If in c3d_sport1m_feature_extraction_frm.sh Need to adjust batch size, stay prototxt The document should also be modified accordingly
10. Check failed: fd != -1 (-1 vs. -1) File not found: conv3d_deepnetA_sport1m_iter_1900000
solve ： In the file ./stage1_rpn_solver60k80k.pt  Of train_net: Change the path to absolute path
