I was using python 3.8 but when I started writing code on face recognition it requires python of 64 bit.. so suggest me either I should uninstall the 32bit python and install 64bit python..(would i loose my installed packages like kivy,pandas,tkinter..etc.) or I can run 64bit and 32bit on my machine simultaneously.

  • You can use pip subcommand "freeze" to get a list and version of all installed packages. this list may be put in a file and used as part of a specification to pip of packages to install. so save the data, uninstall and reinstall the version you want. – LhasaDad Dec 02 '20 at 02:27

So, unfortunately all your python packages will be lost if you uninstall python because they are kept in the same folder:

C:\Python27\Lib\site-packages

You might be able to specifically save this folder, then copy it back into your new installation of python, but don't take my word for it!
