enhance image resolution

Setup the alias. Put this in your .bashrc or .zshrc file so it's available at startup.

alias enhance='function ne() { docker run --rm -v "$(pwd)/`dirname ${@:$#}`":/ne/input -it alexjc/neural-enhance ${@:1:$#-1} "input/`basename ${@:$#}`"; }; ne'

Now run any of the examples above using this alias, without the `.py` extension.

enhance --zoom=1 --model=repair images/broken.jpg

Create a python kernel that jupyter can perceive

conda create -n gpu python pip ipykernel tensorflow-gpu
conda activate gpu
python -m ipykernel install --user --name gpu --display-name gpu

Change multiple files with find and sed

find . -type f -name 'download.sh' -exec sed -i 's/youtube-dl /youtube-dl  --download-archive ytdl-archive-record.txt /g' {} \;

Rsync directory with progress bar and without overwrite

Download Youtube Videos as Audios Files

Install youtube-dl package
- can install it with brew
Use youtube-dl -F url to check what format is available on youtube
Useful options include --ignore-errors \ --no-playlist \ --yes-playlit \ --embed-thumbnail \ -x (output audio)

I use:

youtube-dl -f 140 --yes-playlist --embed-thumbnail --ignore-errors url

to download the playlist with specifying file format code as 140 (.m4a file).

If the file code 140 is not available, one might consider use -x option to force ffmpeg to convert an audio fril. So iCloud Music Library doesn't support the aac and opus from youtube-dl. Maybe the mp3 format will work. So it does work. Here is the recommanded commands for mp3 transformation:

youtube-dl -x --audio-format mp3 --yes-playlist --embed-thumbnail --ignore-errors url

Locally set bash as login sheel from sh

From here:

If you want to fix it locally, you may have to modify your .profile to execute the shell you want:

if [ "$SHELL" != "/bin/bash" ]
then
    export SHELL="/bin/bash"
    exec /bin/bash -l    # -l: login shell again
fi

Trim every file under a given directory

Assign GPU in Jupyter Notebook

%env CUDA_DEVICE_ORDER=PCI_BUS_ID
%env CUDA_VISIBLE_DEVICES=0

import os
os.environ["CUDA_VISIBLE_DEVICES"]="0"

Use the following to test

from tensorflow.python.client import device_lib
print device_lib.list_local_devices()

when using THEANO

THEANO_FLAGS=device=cuda0

THEANO_FLAGS=mode=FAST_RUN,floatX=float32,device=cuda0

THEANO_FLAGS=mode=FAST_RUN,floatX=float32,device=gpu0 python train.py

THEANO_FLAGS=mode=FAST_RUN,floatX=float32,device=gpu2 python

when using Tensor Flow:

Noted that the order of GPUs is reversed on dd0 and dd1.

Profiling

python -m cProfile -s cumtime lwn2pocket.py

Use this if want to write to file

python -m cProfile -s cumtime lwn2pocket.py > profile.txt

Use this if want to duplicate the output to file while keep the one on screen.

python -m cProfile -s cumtime lwn2pocket.py | tee profile.txt

Use this to generate the binary output file.

python -m cProfile -s cumtime -o profile.txt lwn2pocket.py

Read the profile binary file (generated by -o option)

python -m cprofilev -f profile.txt  -p 7777

Rsync

rsync -avz -e "ssh -i /home/yma/.ssh/celje" [email protected]:/home/yma/imagenet /home/yma/imagenet --progress```

rsync with LAN acceleration:
```rsync -aHAXxv --numeric-ids -e "ssh -i /home/yma/.ssh/celje -T -c arcfour -o Compression=no -x" [email protected]:/home/yma/imagenet /home/yma/imagenet --progress

As you have discovered you cannot use rsync with a remote source and a remote destination. Assuming the two servers can't talk directly to each other, it is possible to use ssh to tunnel via your local machine.

Instead of

rsync -vuar host1:/var/www host2:/var/www you can use this

ssh -R localhost:50000:host2:22 host1 'rsync -e "ssh -p 50000" -vuar /var/www localhost:/var/www' In case you're wondering, the -R option sets up a reverse channel from port 50000 on host1 that maps (via your local machine) to port 22 on host2. There is no direct connection from host1 to host2.
