caffe安装简易教程

conda create -n my_caffe python=python2.7 -c defaults

其中my_caffe是新建环境的名字，python=python2.7为该环境的python版本，-c defaults表示使用defaults 的channel安装。注意，最好选用-c defaults方式，否则否则会因为依赖库channel不一致，产生如下问题：

>>> import caffe
Traceback (most recent call last):
  File "", line 1, in 
  File "/home1/fzp/anaconda3/envs/caffe/lib/python2.7/site-packages/caffe/__init__.py", line 1, in 
    from .pycaffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, RMSPropSolver, AdaDeltaSolver, AdamSolver, NCCL, Timer
  File "/home1/fzp/anaconda3/envs/caffe/lib/python2.7/site-packages/caffe/pycaffe.py", line 13, in 
    from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, \
ImportError: /home1/fzp/anaconda3/envs/caffe/lib/python2.7/site-packages/caffe/../../../libcaffe.so.1.0.0: undefined symbol: _ZNK7leveldb6                                                                                                  Status8ToStringB5cxx11Ev

第二步：激活环境
激活刚才创建的conda环境。

conda activate my_caffe

第三步：安装caffe
gpu版：conda install -c defaults caffe-gpu
cpu版：conda install -c defaults caffe

第四步：验证安装成功

python

import caffe

不报错即代表安装成功！
如果出现numpy导入错误，是因为numpy版本过低，可再输入下面命令

pip install numpy --upgrade
