Some Notes

Previously I have written some notes of how to set up environment for Caffe on Ubuntu 14.04. My strategy is DIY. Though the methods mentioned in those notes worked well at that time, they may be out of date now. Since I am quite a rookie in Linux OS, I need this additional note to bypass the problems I met recently.

Concerning setting link directories

New a configuration file in the directory of /etc/ld.so.conf.d/ and the file name must be end up with .conf. In the file is the directories that need to be added to the link path. Finally use command sudo ldconfig to make it effective. Here is an example to add link path of OpenBLAS to the environment. A new file named as openblas.conf is created and saved in /etc/ld.so.conf.d/. In the file a path is written /home/joshua/LIBS/openblas/lib. Then type sudo ldconfig in a terminal window.

Concerning installing NVIDIA GPU drivers

A very easy way to install NVIDIA GPU drivers is using the tools called “Software&Updates” in “System Settings” of Ubuntu. In “Software&Updates” there is a tag “Additional Drivers”, which can be used to select possible GPU drivers. After reboot the new settings can take effect.

Concerning making Caffe

After sudo apt-get update and sudo apt-get upgrade, I found that Caffe can not make. The error came from TIFF. I solved the problem by conda remove libtiff.
