--- OLD STUFF BELOW ---

install package (request here for example)

pip install requests

#Check if pip works / installed modules: (in windows cmd) pip freeze pip list

#check python packages list: (python promot) help("modules")

#1 Install Python (for windows & touchdesigner)

download & install python 64bit v3.6.6 ( executable installer 64 or amd64 )

#--- >make sure the "add to ENV path " option is ticked/

#2 Go to env. variable Copy the path something like C:\Users\pk\AppData\Local\Programs\Python\Python35\

#3 In touch designer change the folder in preference | python 64 bit modules: C:\Users\pk\AppData\Local\Programs\Python\Python35\Lib\site-packages

#4 MULTIPLE PYTHON VERSION: check with py launcher witch version are installed: py --list

then you can target specific version for installing / pip''ing ( start as admin) py -3.7 -m pip install packagename

#5 User vs All User / Machine installs using pip pip3.7 install --upgrade --user mediapipe

#6 Check PATH echo %PATH% echo %PATH:;=&echo.% ( outputs line by line )

#7 Backup PATH ( cmd as admin ) echo %PATH% > C:\path-backup.txt

#8 Add path to PATH Permanently add a directory to the user PATH variable: setx path "%PATH%;C:\path\to\directory"

Permanently add a directory to the system PATH variable (for all users): setx /M path "%PATH%;C:\path\to\directory"
