Caffe-MobileNetSSD下ncnn推理实现-5

安装caffe python接口

(py365) user@ubuntu:~/caffe_ssd/caffe$ pip install -r python/requirements.txt

pip3 install matplotlib

make pycaffe -j8

出现问题：

(py365) user@ubuntu:~/caffe_ssd/caffe$ make pycaffe -j8

touch python/caffe/proto/__init__.py

CXX/LD -o python/caffe/_caffe.so python/caffe/_caffe.cpp

PROTOC (python) src/caffe/proto/caffe.proto

/usr/bin/ld: cannot find -lboost_python3

collect2: error: ld returned 1 exit status

Makefile:519: recipe for target 'python/caffe/_caffe.so' failed

make: *** [python/caffe/_caffe.so] Error 1

解决：

(py365) user@ubuntu:/usr/lib/x86_64-linux-gnu$ sudo ln -s libboost_python-py35.so libboost_python3.so

boost_python3

然后重新开始编译caffe

 

gedit ~/.bashrc

export PYTHONPATH=/home/user/caffe_ssd/caffe/python:$PYTHONPATH

 

(py365) user@ubuntu:~/caffe_ssd/caffe$ source ~/.bashrc

(base) user@ubuntu:~/caffe_ssd/caffe$ python

分析问题：

让Caffe支持Python3，https://www.jianshu.com/p/ea2156fa1206（参考设置conda create --name py365 python=3.6.5环境变量）

解决方法：

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/python3/bin

https://www.cnblogs.com/laosan007/p/11737704.html

export PYTHONPATH=/home/user/caffe_ssd/caffe/python:$PYTHONPATH
