python requirements.txt - unexpected dependencies

Question

After running pip3 install -r requirements.txt

# requirements.txt
...

django~=3.1
djangorestframework~=3.12
django-extensions~=3.0
pygraphviz~=1.6
sphinx~=3.3
...

I see the wrong version of django:

pip freeze

django==3.2.5

I suppose one of the packages in requirements.txt has it as dependency

Reset the factory run time , create virtual environment and then install the requirements . Check versions then ! — Hamza, Aug 06 '21 at 09:35
Try using `django~=3.1.0` in the requirements. For more information see the @roganjosh 's answer. — Yevhen Kuzmovych, Aug 06 '21 at 09:39

There is no issue. This is exactly how it should work. django~=3.1 and 3.2.5 don't differ by a major version.

Operator	Description	Example
~=	Any compatible release. Compatible releases are releases that are within the same major or minor version, assuming the package author is using semantic versioning.	`~=3.1`: version 3.1 or later, but not version 4.0 or later. `~=3.1.2`: version 3.1.2 or later, but not version 3.2.0 or later.
