Describe the problem I installed tensorflow using pip on the virtualenv. The typing-extensions package is conflicted with black package dependency. black==21.8b0 is required typing-extensions>=3.10.0.0. But, tensorflow has 'typing_extensions ~= 3.7.4 dependency. Are there any plans to upgrade the typing-extensions dependency package version?

Provide the exact sequence of commands / steps that you executed before running into the problem

$ python3 -m venv venv
$ . venv/bin/activate
$ pip install -U pip
$ pip install black
$ pip install tensorflow

The commit has been cherry-picked, so the next release candidate should fully resolve this

We need a cherry-pick of 41e6614 into r2.7 branch. We didn’t do it while working on the RC0 release, but I think we should get it for the next RC.

This seems to be fixed on master by https://github.com/tensorflow/tensorflow/commit/41e66148999080da5b2b80a59740a8f2a59f17da. The install_requires is now typing_extensions >= 3.6.6.

Awesome. Will review and approve and merge a while later when we do patch releases.

@mihaimaruseac @woodyza Since there’s consideration of including this change in a 2.6 release, I went ahead and rebased my changes on the r2.6 branch and opened a new PR here: https://github.com/tensorflow/tensorflow/pull/53250

I would have just reopened the old PR, but I had deleted the fork, so that wasn’t possible 😬

If there’s a preference to more exactly match the changes cherry-picked into 2.7, I can change the version constraint to typing-extensions >= 3.6.6 πŸ™‚

RC1 of TF 2.7 should already have this.

For anyone wondering, this did not make it into tensorflow==2.7.0rc0.

This isn’t too surprising to me as I would imagine that freezing the list of things that go into a release would happen several days if not week+ in advance. Releases are hard, especially for projects of this size.

This is good to know in advance though, so thank you for noting that!

For anyone wondering, this did not make it into tensorflow==2.7.0rc0. https://github.com/tensorflow/tensorflow/blob/v2.7.0-rc0/tensorflow/tools/pip_package/setup.py#L94

If just the two are specified then pip is able to figure out the dependency mismatch and find a version of black (v21.7.b0) that will work

Full Example in a python:3.9 Docker image:
$ docker run --rm -ti python:3.9 /bin/bash

(venv) root@12adf30cd4d4:/# python -m pip --quiet install --upgrade pip setuptools wheel
(venv) root@12adf30cd4d4:/# python -m pip install black tensorflow

but that tensorflow is pinning down to the patch release here (typing-extensions~=3.7.4) is pretty restrictive (and making it so that everyone using TensorFlow needs to treat it like an application and not a library. c.f. PR #40789 for another example of problems coming from being overly restrictive, though this is just a historical note as the SciPy dependency has been removed and so no longer affects TensorFlow).

In more complicated environments though I can get pip to fail on this problem.

Edit: Following @alexander-held example below I can get things to install on Python 3.9 but not on Python 3.8. c.f. example in details for pip install black tensorflow tensorflow-probability on Python 3.9

Example with TensorFlow Probability in a python:3.9 Docker image:
$ docker run --rm -ti python:3.9 /bin/bash
