Version requiremnt issues

[ianhi]

After attempting poetry install I'm getting the following errors (with python 3.10)

Updating dependencies
Resolving dependencies... (1.7s)

The current project's Python requirement (>=3.7,<3.12) is not compatible with some of the required packages Python requirement:
  - scipy requires Python >=3.8, so it will not be satisfied for Python >=3.7,<3.8
  - scipy requires Python >=3.8,<3.11, so it will not be satisfied for Python >=3.7,<3.8 || >=3.11,<3.12
  - scipy requires Python >=3.8,<3.11, so it will not be satisfied for Python >=3.7,<3.8 || >=3.11,<3.12
  - scipy requires Python >=3.8,<3.12, so it will not be satisfied for Python >=3.7,<3.8
  - scipy requires Python >=3.8,<3.12, so it will not be satisfied for Python >=3.7,<3.8
  - scipy requires Python >=3.8, so it will not be satisfied for Python >=3.7,<3.8

Because no versions of scipy match >1.8.0,<1.8.1 || >1.8.1,<1.9.0 || >1.9.0,<1.9.1 || >1.9.1,<1.9.2 || >1.9.2,<1.9.3 || >1.9.3
 and scipy (1.8.0) requires Python >=3.8,<3.11, scipy is forbidden.
And because scipy (1.8.1) requires Python >=3.8,<3.11
 and scipy (1.9.0) requires Python >=3.8,<3.12, scipy is forbidden.
And because scipy (1.9.1) requires Python >=3.8,<3.12
 and scipy (1.9.2) requires Python >=3.8, scipy is forbidden.
So, because scipy (1.9.3) requires Python >=3.8
 and jupyter-compare-view depends on scipy (>=1.8.0), version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties
    
    For scipy, a possible solution would be to set the `python` property to ">=3.8,<3.12"
    For scipy, a possible solution would be to set the `python` property to ">=3.8,<3.11"
    For scipy, a possible solution would be to set the `python` property to ">=3.8,<3.11"

Thanks for the report.
The latest commit changed some things in the version requirements: #42
and I guess this broke it.
I'll investigate this in a few hours. Till now, working with the pre-last commit should solve the problem.

I've just tried it with python versions 3.7-3.11 and
it works for 3.8,3.9 and 3.10 for me:

3.7

python3.7 -m venv .venv7
source .venv7/bin/activate
poetry install 
deactivate

fails.

scipy is never actually used so I suggest dropping it from the requirements.

[kolibril13]

scipy is only in the developer dependencies, as can be seen here:

jupyter_compare_view/pyproject.toml

Line 20 in 6323a40

scipy = ">=1.8.0"

so for users It's not there either way.

and SciPy is needed for scikit-image, which provides the example images.
