handling of extra_requires

[anntzer]

scikit-image (https://pypi.python.org/pypi/scikit-image) depends on dask[array] (https://pypi.python.org/pypi/dask) (not visible on PyPI but this can be checked by installing in a clean venv). dask[array] itself depends on toolz and numpy.
pipdeptree does not realize this and considers toolz and numpy to not be dependents of anything after a clean install of scikit-image.

Sorry for replying so late, I missed this issue somehow. What do you mean by "not visible on PyPI"? pipdeptree internally calls functions in the pip and pkg_resources modules. Hence it can only identify dependencies that pip can.

[anntzer]

PyPI shows the line

Requires matplotlib (>= 1.3.1), numpy (>= 1.7.2), scipy (>= 0.9.0), six (>= 1.7.3), networkx (>= 1.8), pillow (>= 2.1.0), dask (>= 0.5.0)

This dependency is visible at /usr/lib/python3.5/site-packages/scikit_image-0.12.3-py3.5.egg-info/requires.txt (or the equivalent on your OS), which contains the lines

six>=1.7.3
networkx>=1.8
pillow>=2.1.0
dask[array]>=0.5.0

pip does know about the dependency (well, it's able to resolve it...) but I'm not sure pip or pkg_resources expose it though...

[naiquevin]

Ok. I'll have a look at it. Thanks.

Looks like this is the same as pypa/pipenv#1013
See there for additional detail.

For future reference:

• This pipdeptree issue is not duplicated by that pipenv issue.
• The pipenv issue depends on this pipdeptree issue to solve the pipenv issue since pipenv depends on pipdeptree. (the pipenv issue is closed as "out of scope").

[gaborbernat]

This should be no longer the case.

Hi, unfortunately, this seems to still be a problem.

To replicate this, I created a fresh virtualenv with just pipdeptree and django-import-export 3.2.0

django-import-export==3.2.0 depends on tablib[html,ods,xls,xlsx,yaml]>=3.4.0 in it's install_requires
tablib==3.5.0 depends on the following:

[project.optional-dependencies]
all = [
    "markuppy",
    "odfpy",
    "openpyxl>=2.6.0",
    "pandas",
    "pyyaml",
    "tabulate",
    "xlrd",
    "xlwt",
]
cli = ["tabulate"]
html = ["markuppy"]
ods = ["odfpy"]
pandas = ["pandas"]
xls = ["xlrd", "xlwt"]
xlsx = ["openpyxl>=2.6.0"]
yaml = ["pyyaml"]

Which can be seen in tablib-3.5.0-py3-none-any.whl/tablib-3.5.0.dist-info/METADATA as the following lines:

Provides-Extra: all
Requires-Dist: markuppy ; extra == 'all'
Requires-Dist: odfpy ; extra == 'all'
Requires-Dist: openpyxl (>=2.6.0) ; extra == 'all'
Requires-Dist: pandas ; extra == 'all'
Requires-Dist: pyyaml ; extra == 'all'
Requires-Dist: tabulate ; extra == 'all'
Requires-Dist: xlrd ; extra == 'all'
Requires-Dist: xlwt ; extra == 'all'
Provides-Extra: cli
Requires-Dist: tabulate ; extra == 'cli'
Provides-Extra: html
Requires-Dist: markuppy ; extra == 'html'
Provides-Extra: ods
Requires-Dist: odfpy ; extra == 'ods'
Provides-Extra: pandas
Requires-Dist: pandas ; extra == 'pandas'
Provides-Extra: xls
Requires-Dist: xlrd ; extra == 'xls'
Requires-Dist: xlwt ; extra == 'xls'
Provides-Extra: xlsx
Requires-Dist: openpyxl (>=2.6.0) ; extra == 'xlsx'
Provides-Extra: yaml
Requires-Dist: pyyaml ; extra == 'yaml'

Unfortunately, pipdeptree appears to be unable to find the dependency between `tablib` and it's optional dependencies

This is my pip freeze output:

(.venv) C:\Users\JayTurner\Desktop> pip freeze
asgiref==3.7.2
defusedxml==0.7.1
diff-match-patch==20230430

PyYAML==6.0.1
sqlparse==0.4.4
tablib==3.5.0
tzdata==2023.3
xlrd==2.0.1
xlwt==1.3.0

This is my pipdeptree output:

I have also tried on pipdeptree 2.3.0, 2.3.1 and 2.3.2, which were the releases just before, just after and a bit after your comment on September 6th, 2022, none of which seem to work as expected.

[TurnrDev]

Interestingly, pipdeptree[test]'s own dependencies don't show as related to pipdeptree. Perhaps that might be an easy way to test that functionality is working.

[TurnrDev]

I see this might be related to #107 too

[TurnrDev]

I see it's due to lack of resources. I won't bother you no more!

PR welcome 🤗

[TurnrDev]

I'll see what I can do, but no promises ☺️
