Caffer Ubuntu Installation

Since the official documentation gives the installation requirements of each version and the meaning of some of the parameters of the config file, not careful enough (of course all the Config parameter meanings are explained in the file), here I am recording the complete process of compiling the Caffe CPU version with Anaconda3 alone.

Environment:

ubuntu 14.04anaconda3python3.5编译版本:纯cpu版
1. Reliance

2. Configuration

Modify the configuration file as follows:

# # Refer to http://caffe.berkeleyvision.org/installation.html# Contributions simplifying and improving our build system is welcome!# CuDNN Acceleration switch (uncomment to build with CuDNN).# Use_cudnn: = 1# cpu-only switch (uncomment to build without GPU support).Cpu_only: =1# Uncomment to disable IO dependencies and corresponding data layers# Use_opencv: = 0# Use_leveldb: = 0# Use_lmdb: = 0# Uncomment to allow Mdb_nolock when reading LMDB files (only if necessary)# You should no set this flag if you'll be a reading Lmdbs with any# Possibility of simultaneous read and write# Allow_lmdb_nolock: = 1# Uncomment if you ' re using OpenCV 3# Opencv_version: = 3# To customize your choice of compiler, uncomment and set the following.# N.B.

Compile

The project root directory runs the following instruction to compile (-j means to turn on four thread compilations):

make pycaffe -j 4

You may experience the following issues:

CXX .build_release/src/caffe/proto/caffe.pb.ccPROTOC (python) src/caffe/proto/caffe.protoLD -o .build_release/lib/libcaffe.so.1.0.0-rc3CXX/LD -o python/caffe/_caffe.so python/caffe/_caffe.cpp/usr/bin/ld: cannot find -lboost_python3collect2: error: ld returned 1 exit statusmake: *** [python/caffe/_caffe.so] 错误 1

PYTHON_LIBRARIES := boost_python3This library file cannot be found in the system because it is in line 74th of the configuration file boost_python3.lib .

The solution is as follows:

Check if you have the following files:

ls /usr/lib/x86_64-linux-gnu/libboost_python-py34.so

If so, it means that the library file is already in our system, except the file name is different.

cd /usr/lib/x86_64-linux-gnu/sudo ln -s libboost_python-py34.so libboost_python3.so

Recompile to pass.

Test

After entering the Python interpreter environment, use the following command to test whether the installation was successful.

? /home/david/download/caffe-master >python Python 3.5.0 |Anaconda 2.4.0 (64-bit)| (default, Oct 19 2015, 21:57:25) [GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linuxType "help", "copyright", "credits" or "license" for more information.>>> import caffe

The following error may occur:

Failed to include caffe_pb2, things might go wrong!Traceback (most recent call last):  File "<stdin>", line 1, in <module>  File "/home/david/download/caffe-master/python/caffe/__init__.py", line 4, in <module>    from .proto.caffe_pb2 import TRAIN, TEST  File "/home/david/download/caffe-master/python/caffe/proto/caffe_pb2.py", line 7, in <module>    from google.protobuf import reflection as _reflection  File "/home/david/opt/anaconda3/lib/python3.5/site-packages/google/protobuf/reflection.py", line 68, in <module>    from google.protobuf.internal import python_message  File "/home/david/opt/anaconda3/lib/python3.5/site-packages/google/protobuf/internal/python_message.py", line 848    except struct.error, e:                       ^SyntaxError: invalid syntax

This is because PROTOBUF does not support Python3, the solution is pip install protobuf-py3 to install, a python3.x version of the replacement package.
