Hello @kartik,

You can use the following Python code. Unlike pip freeze, this will not print warnings and FIXME errors. For pip < 10.0.1

import pip
from subprocess import call

packages = [dist.project_name for dist in pip.get_installed_distributions()]
call("pip install --upgrade " + ' '.join(packages), shell=True)

For pip >= 10.0.1

import pkg_resources
from subprocess import call

packages = [dist.project_name for dist in pkg_resources.working_set]
call("pip install --upgrade " + ' '.join(packages), shell=True)

Hope this work!

  • Open the command prompt and check the version of pip using 'pip -V'.
  • Check the outdated packages using 'pip list --outdated' output is similar to above example.
  • run 'notepad requirements.txt' on command prompt and package similar to below screenshot. save the file.
  • Run the  command 'pip install -r requirements.txt' and all module should be installed
  • If some module is not updating then we use this command 'pip install --user -r requirements.txt'
