As  almenon pointed out  this no longer works and it is not the supported way to get package information in your code  The following raises an exception   import pip installed packages   dict   package project name  package version                              for package in pip get installed distributions       To accomplish this  you can import pkg resources  Here s an example   import pkg resources installed packages   dict   package project name  package version                             for package in pkg resources working set     I m on v3 6 5

Newer versions of pip have the ability to do what the OP wants via pip list -l or pip freeze -l  --list   On Debian  at least  the man page doesn t make this clear  and I only discovered it - under the assumption that the feature must exist - with pip list --help   There are recent comments that suggest this feature is not obvious in either the documentation or the existing answers  although hinted at by some   so I thought I should post  I would have preferred to do so as a comment  but I don t have the reputation points

Start with     pip list   To list all packages  Once you found the package you want  use     pip show  lt package-name gt    This will show you details about this package  including its folder  You can skip the first part if you already know the package name  Click here for more information on pip show and here for more information on pip list   Example     pip show jupyter Name  jupyter Version  1 0 0 Summary  Jupyter metapackage  Install all the Jupyter components in one go  Home-page  http   jupyter org Author  Jupyter Development Team Author-email  jupyter googlegroups org License  BSD Location   usr local lib python2 7 site-packages Requires  ipywidgets  nbconvert  notebook  jupyter-console  qtconsole  ipykernel

If Debian behaves like recent Ubuntu versions regarding pip install default target  it s dead easy  it installs to  usr local lib  instead of  usr lib  apt default target   Check https   askubuntu com questions 173323 how-do-i-detect-and-remove-python-packages-installed-via-pip 259747 259747  I am an ArchLinux user and as I experimented with pip I met this same problem  Here s how I solved it in Arch   find  usr lib python2 7 site-packages -maxdepth 2 -name   init   py   xargs pacman -Qo   grep  No package    Key here is  usr lib python2 7 site-packages  which is the directory pip installs to  YMMV  pacman -Qo is how Arch s pac kage man ager checks for ownership of the file  No package is part of the return it gives when no package owns the file  error  No package owns  FILENAME  Tricky workaround  I m querying about   init   py because pacman -Qo is a little bit ignorant when it comes to directories     In order to do it for other distros  you have to find out where pip installs stuff  just sudo pip install something   how to query ownership of a file  Debian Ubuntu method is dpkg -S  and what is the  no package owns that path  return  Debian Ubuntu is no path found matching pattern   Debian Ubuntu users  beware  dpkg -S will fail if you give it a symbolic link  Just resolve it first by using realpath  Like this   find  usr local lib python2 7 dist-packages -maxdepth 2 -name   init   py   xargs realpath   xargs dpkg -S 2 gt  amp 1   grep  no path found    Fedora users can try  thanks  eddygeek    find  usr lib python2 7 site-packages -maxdepth 2 -name   init   py   xargs rpm -qf   grep  not owned by any package

If you use the Anaconda python distribution  you can use the conda list command to see what was installed by what method   user pc     conda list   packages in environment at  anaconda3      Name                    Version                   Build  Channel  ipyw jlab nb ext conf    0 1 0            py36h2fc01ae 0 alabaster                 0 7 10           py36h174008c 0 amqp                      2 2 2                      lt pip gt  anaconda                  5 1 0                    py36 2 anaconda-client           1 6 9                    py36 0   To grab the entries installed by pip  including possibly pip itself    user pc     conda list   grep   lt pip amqp                      2 2 2                      lt pip gt  astroid                   1 6 2                      lt pip gt  billiard                  3 5 0 3                    lt pip gt  blinker                   1 4                        lt pip gt  ez-setup                  0 9                        lt pip gt  feedgenerator             1 9                        lt pip gt    Of course you probably want to just select the first column  which you can do with  excluding pip if needed    user pc     conda list   awk   3    pip   if   1     pip   print  1   amqp         astroid billiard blinker ez-setup feedgenerator    Finally you can grab these values and pip uninstall all of them using the following   user pc     conda list   awk   3    pip   if   1     pip   print  1     xargs pip uninstall -y   Note the use of the -y flag for the pip uninstall to avoid having to give confirmation to delete

The below is a little slow  but it gives a nicely formatted list of packages that pip is aware of   That is to say  not all of them were installed  by  pip  but all of them should be able to be upgraded by pip     pip search     egrep -B1  INSTALLED LATEST    The reason it is slow is that it lists the contents of the entire pypi repo   I filed a ticket suggesting pip list provide similar functionality but more efficiently    Sample output   restricted the search to a subset instead of     for all      pip search selenium   egrep -B1  INSTALLED LATEST   selenium                  - Python bindings for Selenium   INSTALLED  2 24 0   LATEST     2 25 0 -- robotframework-selenium2library - Web testing library for Robot Framework   INSTALLED  1 0 1  latest
