How to install Zoom virtual background on Linux

1. Install newest version of Zoom (link) 

2. Install unity-tweak-tool (I'm not sure if this is really necessairy but it started working after I installe it) 

3. Install Zoom Media plugin (link), I clicked on Citrix and Ubuntu because this is for my Mint laptop. I'll try tomorrow also on the Manjaro one. 

4, Find your ZoomMedia.ini in /etc/zoomvdi (Note, this appears after you install 3.)

5. Edit it to turn SMARTVB=0 to SMARTVB=1

To change the background, right click on the screen of the Zoom linux client, because of course, there's no simply Option to do it otherwise. But it works. Even if it took me 1 hour to figure it out.

How to kill a zombi plasmashell

 I had a case of plasmashell turning into a zombi. This is what I did to solve it:

The correct way to restart plasmashell is trough:   "plasmashell --replace &"

However, the old plasmashell was a zombi for some reason so I had to first kill it with:
 

 523  sudo killall plasmashell
 524  sudo kill {pid of the proces}
 525  ps aux | grep plasmashell
 526  cat /proc/{pid of the process}/status
 527  sudo kill {pid} 
 531  ps o ppid {pid}
 533  ps aux | grep -w Z   #shows zombi processes
 535  ps o ppid {pid}
 536  sudo kill -1 {pid}  
 539  grep plasma*
# 540  killall plasmashell && kstart5 plasmashell& #this seems to be the old way to do it

Then Alt+F2 and
plasmashell --replace &

How to install polychord with conda

 That was a long battle, but it seems now all is fine. I'm using Manjaro, since Sabayon has no longer installation images with new kernels and Mocaccino is still not ready. But it seems Arch and Gentoo are not sooo different. Anyway, back to python. So this was an epic fight including downgrading binutils (of course) and installing pretty much any gfortran package out there. Here's some of what I did:

conda create --name MyEnv
conda activate MyEnv
conda install -n MyEnv pip
cd anaconda3/bin
source activate MyEnv
pip install https://github.com/PolyChord/PolyChordLite/archive/master.zip
conda install -c anaconda ipykernel
python3 -m ipykernel install --user --name=MyEnv
pip install emcee
pip install pil
pip install matplotlib
pip install arviz
pip install getdist

Alternative installation without conda:

pip install notebook

#jupyter notebook #to start it

conda deactivate

conda config --set auto_activate_base false #to deactivate conda permanently

pip install https://github.com/PolyChord/PolyChordLite/archive/master.zip

pip install build (or anything that is missing)

also don't forget to install gcc and gcc++ as they are critical for the successful installation. 

 

Below is what is currently installed in this conda env. I have no idea what I have in the base conda and in pip in general as I pretty much installed anything:

P.S. I was getting two types of errors: " ImportError: No module named 'commands ..." (this was related to installing os_sys which in the end, I don't think I need at all.  

The other error was "wheel error" which the new enviornment solved automatically. And the third one was that "f77: No such file or directo'ry", also some mix-up between the gfortran I had installed and the default name of the
