Could please try this one(A bit long though, maybe there are better solutions):

$ pip list | xargs pip show | grep -E 'Location:|Name:' | cut -d ' ' -f 2 | paste -d ' ' - - | awk '{print $2 "/" tolower($1)}' | xargs du -sh 2> /dev/null

the output should look like this:

80K     /home/lord63/.pyenv/versions/2.7.11/envs/py2/lib/python2.7/site-packages/blinker
3.8M    /home/lord63/.pyenv/versions/2.7.11/envs/py2/lib/python2.7/site-packages/docutils

...

should works if the package is installed in Location/Name. (location and name are from pip show <package>)

pip show <package> will show you the location:

we get the Name and Location to join them to get the location, finally use du -sh to get the package size.

History :

There is no command or applications developed for that purpose at the moment, we need to check that manually

Manual Method I :

du /usr/lib/python3.5/ --max-depth=2 | sort -h
du /usr/lib64/python3.5/ --max-depth=2 | sort -h

This does not include packages/files installed out of that directory, thus said we will get 95% with those 2 simples command

Also if you have other version of python installed, you need to adapt the directory

Manual Method II :

pip list | sed '/Package/d' | sed '/----/d' | sed -r 's/S+//2' | xargs pip show | grep -E 'Location:|Name:' | cut -d ' ' -f 2 | paste -d ' ' - - | awk '{print $2 "/" $(find $2 -maxdepth 1 -iname $1)}' | xargs du -sh  | sort -h

Search the install directory with the package name with case insensitive

Manual Method II Alternative I :

pip list | sed '/Package/d' | sed '/----/d' | sed -r 's/S+//2' | xargs pip show | grep -E 'Location:|Name:' | cut -d ' ' -f 2 | paste -d ' ' - -| awk '{print $2 "/" tolower($1)}' | xargs du -sh | sort -h

Search the install directory with the package name with lowered case

Manual Method II Alternative II :

pip list | sed '/Package/d' | sed '/----/d' | sed -r 's/S+//2' | xargs pip show | grep -E 'Location:|Name:' | cut -d ' ' -f 2 | paste -d ' ' - -| awk '{print $2 "/" $1}' | xargs du -sh | sort -h

Search the install directory with the package name

Note :

For methods using du, output lines starting with du: cannot access need to be checked manually;
The command use the install directory and add to it the name of the package but some times the package name and directory name are different…

Make it simple :

• Use first method then
• Use second method and just check manually package outside python classic directory

New version for new pip list format:

pip2 list --format freeze|awk -F = {'print $1'}| xargs pip2 show | grep -E 'Location:|Name:' | cut -d ' ' -f 2 | paste -d ' ' - - | awk '{print $2 "/" tolower($1)}' | xargs du -sh 2> /dev/null|sort -h

Modified for pip version 18 and above:

pip list | tail -n +3 | awk '{print $1}' | xargs pip show | grep -E 'Location:|Name:' | cut -d ' ' -f 2 | paste -d ' ' - - | awk '{print $2 "/" tolower($1)}' | xargs du -sh 2> /dev/null | sort -hr

This command shows pip packages, sorted by descending order of sizes.

Here’s how,

1. pip3 show numpy | grep "Location:"
2. this will return path/to/all/packages
3. du -h path/to/all/packages
4. last line will contain size of all packages in MB

Note: You may put any package name in place of numpy

All of the above solutions do not list packages with dashes in them: PIP converts them to underscores in the folder names:

pip list --format freeze | awk -F = {'print $1'} | xargs pip show | grep -E 'Location:|Name:' | cut -d ' ' -f 2 | paste -d ' ' - - | awk '{gsub("-","_",$1); print $2 "/" tolower($1)}' | xargs du -sh 2> /dev/null | sort -h

And for Mac users:

pip3 list --format freeze | awk -F = {'print $1'} | xargs pip3 show | grep -E 'Location:|Name:' | cut -d ' ' -f 2 | paste -d ' ' - - | awk '{gsub("-","_",$1); print $2 "/" tolower($1)}' | xargs du -sh 2> /dev/null | sort -h

How

 $ du -h -d 1 "$(pip -V | cut -d ' ' -f 4 | sed 's/pip//g')" | grep -vE "dist-info|_distutils_hack|__pycache__" | sort -h

Pros

No need to convert these:
case (Django:django)
hyphen (django-q:django_q)
naming (djangorestframework-gis:rest_framework_gis)

Cons

Dependencies and some unknown directories revealed as well…

There is a simple Pythonic way to find it out though.

Here is the code. Let’s call this file pipsize.py.

import os
import pkg_resources

def calc_container(path):
    total_size = 0
    for dirpath, dirnames, filenames in os.walk(path):
        for f in filenames:
            fp = os.path.join(dirpath, f)
            total_size += os.path.getsize(fp)
    return total_size



dists = [d for d in pkg_resources.working_set]

for dist in dists:
    try:
        path = os.path.join(dist.location, dist.project_name)
        size = calc_container(path)
        if size/1000 > 1.0:
            print (f"{dist}: {size/1000} KB")
            print("-"*40)
    except OSError:
        '{} no longer exists'.format(dist.project_name)

When run with python pipsize.py this will print out something like,

You can just run part 1 by it’s self for all the current packages python tool-size.py will total them all up for you

If you want to know the exact size of a particular pip package including all its dependencies, i’ve created a little bash and python combo to achieve this

( based off the excellent package walking code answer above https://stackoverflow.com/a/67914559/3248788 )

Steps :

1. create a python script to check all currently installed pip packages
2. create a shell script to create a brand new python environment and install package to test, and run the script from step 1
3. run shell script
4. profit 🙂

Step 1

create a python script called tool-size.py

#!/usr/bin/env python

import os
import pkg_resources

def calc_container(path):
    total_size = 0
    for dirpath, dirnames, filenames in os.walk(path):
        for f in filenames:
            fp = os.path.join(dirpath, f)
            total_size += os.path.getsize(fp)
    return total_size

def calc_installed_sizes():
    dists = [d for d in pkg_resources.working_set]

    total_size = 0
    print (f"Size of Dependencies")
    print("-"*40)
    for dist in dists:
        # ignore pre-installed pip and setuptools
        if dist.project_name in ["pip", "setuptools"]:
            continue
        try:
            path = os.path.join(dist.location, dist.project_name)
            size = calc_container(path)
            total_size += size
            if size/1000 > 1.0:
                print (f"{dist}: {size/1000} KB")
                print("-"*40)
        except OSError:
            '{} no longer exists'.format(dist.project_name)

    print (f"Total Size (including dependencies): {total_size/1000} KB")

if __name__ == "__main__":
    calc_installed_sizes()

Step 2

create a bash script called tool-size.sh

#!/usr/bin/env bash

# uncomment to to debug
# set -x

rm -rf ~/.virtualenvs/tool-size-tester
python -m venv ~/.virtualenvs/tool-size-tester
source ~/.virtualenvs/tool-size-tester/Scripts/activate
pip install -q $1
python tool-size.py
deactivate

Step 3

run script with package you want to get the size of

tool-size.sh xxx

say for truffleHog3

$ ./tool-size.sh truffleHog3

Size of Dependencies
----------------------------------------
truffleHog3 2.0.6: 56.46 KB
----------------------------------------
smmap 4.0.0: 108.808 KB
----------------------------------------
MarkupSafe 2.0.1: 40.911 KB
----------------------------------------
Jinja2 3.0.1: 917.551 KB
----------------------------------------
gitdb 4.0.7: 320.08 KB
----------------------------------------
Total Size (including dependencies): 1443.81 KB
