Bash script to check files in list exist in directory

#Check Files in list from file exist or doesn't exist in directory.
if [ $# -eq 0 ] || [ $# -eq 1 ]
then
echo "You must pass the path to file with the list and the path to directory to check files. \nsh check-file-exist-from-list.sh path/to/file path/to/directory"

AruniRC / video_frames.py
Created July 17, 2018 16:56
Get number of frames using Scikit-video and Python
'''
Sometimes it is useful to know the total number of video frames before starting to iterate.
This is not possible using the default video reader in Sk-video.
The snippet below shows how to do this using the FFMPEG reader instead.
'''
if osp.exists(video_path):
vid_reader = skvideo.io.FFmpegReader(video_path) # NOTE: not the standard skvideo.io.vreader
else:
raise IOError('Path to video not found: \n%s' % video_path)

Setup Caffe2 and Detectron on cluster

Caffe2 setup

  • Copy the caffe2 folder from /mnt/nfs/work1/elm/hzjiang/Share/caffe2 to your own work/toolboxes folder. For me this was /home/arunirc/work1/Tools/caffe2/build.
  • Warning: make sure to remove Anaconda paths in your .bashrc, if any.
export PYTHONPATH=/mnt/nfs/work1/elm/arunirc/Tools/caffe2/build:$PYTHONPATH
export LD_LIBRARY_PATH=/mnt/nfs/work1/elm/arunirc/Tools/caffe2/build/lib:$LD_LIBRARY_PATH

One-liners in bash that come in handy
# A dataset like WIDER-face has folders like:
# 0--Parade 21--Festival 33--Running
# 45--Balloonist 57--Angler 10--People_Marching
# This one-liner splits on '--', takes the second sub-string and gets rid of the '_'
# NOTE: example usage of awk
ls | awk -F'--' '{printf "%s\n", $2}' | awk -F'_' '{printf "%s %s\n", $1, $2}'
