Caffe Python development environment Settings __python

installing Python-dependent libraries

The following two libraries need to be installed because of the need to compile the Python Third-party library

$ sudo yum install python-devel numpy

Setting up the VIRTUALENV environment

$ virtualenv caffeenv
$ cd caffeenv
$ bin/activate

Install the Python third Party library

CD <path_to_caffe>/caffe-1.0/python
pip Install-r requirements.txt

compiling Pycaffe

$ make Pycaffe

Test

First you need to set the environment variable Pythonpath, as follows:

$ export Pythonpath=<path_to_caffe>/caffe-1.0/python: $PYTHONPATH

Run Python, go to interactive mode, and then use "Import Caffe" to test the environment.

Import Caffe

problem

In the construction of the environment also encountered a number of problems, is summarized as follows: The problem of a

The following error occurred while "Import Caffe"

The workaround is to set the PYTHONPATH environment variable before running Python.

Export Pythonpath=/home/jhadmin/downloads/caffe-1.0/python: $PYTHONPATH
