python - 使用 anaconda2 安装 python caffe (pycaffe)

Question

我正在努力运行这个演示 https://github.com/ZheC/Realtime_Multi-Person_Pose_Estimation

我正在运行 ubuntu 14.04

我已经安装了 Anaconda，在安装了很多很多依赖项之后，又弹出了一个依赖项。它还需要python caffe

所以我用这个命令安装它: (我也试过 Pip install caffe 但如果失败了)

Conda install caffe

但是当我尝试运行它时，我得到:

$python
>>> import caffe
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/gtkratosman-lap/anaconda2/lib/python2.7/site-packages/caffe/__init__.py", line 1, in <module>
    from .pycaffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, RMSPropSolver, AdaDeltaSolver, AdamSolver, NCCL, Timer
  File "/home/gtkratosman-lap/anaconda2/lib/python2.7/site-packages/caffe/pycaffe.py", line 13, in <module>
    from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, \
ImportError: libprotobuf.so.12: cannot open shared object file: No such file or directory

Answer 1

我已经能够在我自己的 Anaconda 环境中验证此行为，在 Python v2.7.14 虚拟环境中运行 conda v4.3.27，安装 caffe v1.0.0rc5。

进一步研究该问题后，它似乎与以下 Unresolved Anaconda 问题有关:caffe needs to pin protobuf requirement to version #6733

如问题中所述:

The caffe and caffe-gpu package in defaults has a requirement on protobuf without any version dependencies. Unfortunately, the caffe packages links to libprotobuf.so.12 which is provided by the protbuf version 3.2.0

因此，我发现我能够通过首先手动安装 protobuf v3.2.0，在我的 Anaconda 虚拟环境中运行的 Python 中成功import caffe，如下所示:conda install protobuf ==3.2.0
