Install improved_dense_trajectories code on vision machines

https://gist.github.com/dineshj1/873850c07a0ff2a5a899a14008dc8abe

Run install_IDT_code.sh, but this will run into errors at first. Follow the instructions given in install_IDT_code.sh to edit Makefile. That should do the job.

Setting primary group on UTCS machines

The code snippet in https://gist.github.com/dineshj1/d6b975a8d3d160e95c69 should be added to the end of the .profile file.

NOTE: This causes issues with getting graphics working on eldar-1.

Screenshot shortcuts on a new Linux Mint OS

Linux Mint 17.3 did not have the keyboard shortcuts for screenshots of selected areas working.
I want the behavior to be:

• Shift-PrintScr = save selected area screenshot (to /home/<username>/Pictures/)
• Ctrl-Shift-PrintScr = copy selected area screenshot to clipboard

The following steps proved sufficient:

• Copy scripts from https://gist.github.com/dineshj1/d2c671a3ad82f89879c2
  
• Navigate to keyboard>shortcuts>custom shortcuts
• Add shortcut commands: 
• bash /home/dineshj/screenshot_area.sh, with keyboard bindings: Shift+Print 
• bash /home/dineshj/screenshot_area_to_clipboard.sh, with keyboard bindings: Ctrl+Shift+Print 

Compiling and submitting matlab scripts to condor on the UTCS cluster

Gist at: https://gist.github.com/dineshj1/935a703f93c12a3efc19

1. Write the script in condor-compatible way: (see https://gist.github.com/dineshj1/935a703f93c12a3efc19#file-sample_condorized_function-m, and read tips and details)
2. Compile code after adding all necessary paths to Matlab path: (see https://gist.github.com/dineshj1/935a703f93c12a3efc19#file-compilecodes-m-example)
3. Create submit script: (see https://gist.github.com/dineshj1/935a703f93c12a3efc19#file-sample_submit_file)
4. Some edits to PATH, LD_LIBRARY_PATH etc. may be necessary (see full .profile at https://gist.github.com/dineshj1/935a703f93c12a3efc19#file-profile-when-working): 
1. export PATH=$PATH:/lusr/share/software/matlab-r2015b/bin/glnxa64/:/lusr/share/software/matlab-r2015b/toolbox/compiler/deploy/;
2. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/v/filer4b/software/matlab-r2015b/bin/glnxa64/:/v/filer4b/software/matlab-r2015b/runtime/glnxa64/;
3. export MCR_CACHE_ROOT=/scratch/vision/dineshj/mcrCache/ # where executables will extract ctf archives
4. export KMP_DUPLICATE_LIB_OK=true;

Python jobs on condor

Condor submit file could look like:

+Group="GRAD"
+Project="AI_ROBOTICS"
+ProjectDescription=""
Universe = vanilla
Getenv = True
Log    = ../SUN_download_condor.log
Output = ../SUN_download_condor.out
Error  = ../SUN_download_condor.err
Executable = ./download_SUN_large_panos.py
Queue 100

And the python script itself could look like:

#!/usr/bin/env python

import os
import urllib
import sys

def touch(fname, times=None):
  with open(fname, 'a'):
    os.utime(fname, times)

target_root='./dataset/9104x4552/';
if not os.path.exists(target_root):
  os.mkdir(target_root);


Note the header at the top (shown in bold). This is important for condor to know how to execute the script.

Also, obviously, the python script would have to have executable permissions.
