Render the dependency graph for your conda environment (needs graphviz!)

render_env.py

import json
import glob
import os
from os.path import join, basename
# install this with "conda install -c conda-forge python-graphviz"
import graphviz as gv

# path to your conda environment
path = os.environ.get('CONDA_PREFIX')
if path is None:
    print("Not in a conda environment, activate a conda env or set CONDA_PREFIX to the conda env you want to render before calling this script")
    sys.exit(1)

dg = gv.Digraph(filename='env-%s' % basename(path), format='svg')

for json_file in glob.glob(join(path, 'conda-meta', '*.json')):
    print('reading', json_file)
    j = json.load(open(json_file))
    dg.node(j['name'])
    for dep in j.get('depends', []):
        dg.edge(j['name'], dep.split(' ')[0])

dg.render()
