Pip freeze packages that are actually imported

I have a (Django) project with lots of imports that I started without virtualenv. Is there a way to

pip freeze

only the Python packages that are actually imported somewhere in the project, i.e. they are required by my project?

pip freeze

would list all the packages installed in my system, but I would only need those ones that are used by my project.

A manual solution could be

Find the packages with grep

grep -r import ./*/*[.py] > j.t

Iterate all the lines in j.t with python

fromIndex = line.find('from')
importIndex = line.find('import')
if fromIndex != -1:
    return = line[fromIndex + 5 : importIndex - 1][5:]
else:
    return = line[importIndex + 7:]

Remove all the duplicates

Pip freeze in the virtual env for find the version number

Pip freeze out the virtual env for find the other version number
