http://www.th7.cn/Program/Python/201510/641841.shtml中说使用sys.path.append实际上可用：

import sys

sys.path.append("/home/xxx/project/caffe-master/python")

http://*.com/questions/33371954/pycharm-import-caffe-error/33397590说修改/etc/ld.so.conf。修改了之后，不管用。但是该网址中图片内已经贴出使用sys.path.insert来增加路径。实际上也是可以的：

import sys

sys.path.insert(0, "/home/xxx/project/caffe-master/python")

http://askubuntu.com/questions/684550/importing-a-python-module-works-from-command-line-but-not-from-pycharm中Mihai Capotă指出，由于pycharm并不读取.bashrc中的内容，因而在命令行中能使用import python，但是pycharm中依旧不能使用python。解决方法是：As an alternative to setting the paths in PyCharm, you can simply start PyCharm from a Bash shell to give it access to the environment variables you set in .bashrc.（从bash shell中启动pycharm，使pycharm能读取.bashrc中的环境变量）——这个没试过。
