Caffe安装问题汇总

1.cannot open shared object file no such file or directory runtest error 127 caffe

export LD_LIBRARY_PATH=/usr/local/cuda-6.5/lib64:$LD_LIBRARY_PATH
ldconfig /usr/local/cuda-6.5/lib64/
$ make clean
$ make all -j8

2.Training LeNet on MNIST with Caffe

~/work/caffe@cherry-com(20205)$ ./examples/mnist/train_lenet.sh

3.make pycaffe

首先导入Python的路径

export PYTHONPATH=$PYTHONPATH:/home/vr/Documents/Caffe/setup/caffe-master/python/caffe

在$caffe-root中

make pycaffe

4.boost安装

sudo apt-get install libboost-all-dev

sudo apt-get install apt-file
apt-file update
apt-file search bzlib.h

sudo apt-get install libboost-python1.55.0

sudo apt-get install libboost-all-dev
Or you can call

aptitude search boost

5.常用make

make clean
rm -rf build
make all -j8
make pycaffe
make distribute
make test -j8
make runtest -j8

6.No to_python (by-value) converter found for C++ type: boost::shared_ptr<caffe::Blob<float> >

I managed to get it working with boost 1.6 by editing
the python/caffe/_caffe.cpp file and registering the Blobs shared pointer. I.e in line 257 or so add:

// Fix for caffe pythonwrapper for boost 1.6
boost::python::register_ptr_to_python<boost::shared_ptr<Blob<Dtype> > >();
// End fix

bp::class_<Blob<Dtype>, boost::shared_ptr<Blob<Dtype> >, boost::noncopyable>(
"Blob", bp::no_init)
