Upgrade to pandas 2

[stefanbischof]

Hi,

could you upgrade the dependency to pandas to version >= 2.0.0?

The issue is that rdfpandas currently doesn't work with pandas >= 2.0.0. Since I have to use pandas < 2.0.0, I also have to use an older version of numpy < 1.26. Now, it is not possible to install numpy on python 3.12 because it doesn't PEP513 builds (see https://stackoverflow.com/questions/77582651/why-doesnt-numpy-support-pep517-builds). So I have to resort to python 3.11.

Long story short: please upgrade to pandas >= 2.0.0 so we can use rdfpandas with python 3.12 :)

Hi Stefan, I'm just looking at the requirements.txt and setup.py, and they both list pandas>=2.0.0 (the change was made in version 1.1.6 here on GitHub https://github.com/cadmiumkitty/rdfpandas/releases/tag/1.1.6 and here https://pypi.org/project/rdfpandas/). I am a little unsure what went on with the readthedocs in the meantime, as it seems to list 1.1.5 as the latest version available; I will need to look into it. What version of rdfpandas are you using?

Hi, I am/was using version 1.1.5.

Thanks for the hint with version 1.1.6. That lead me to the solution, to adapt the version specifier for python to >=3.11,<4. I had to explicitly exclude python 4 and upgrad the python minimum version. Some details below for others in the future.

Now, I fixed the version of rdfpandas to be >= 1.1.6 then this happened:

> poetry update
Updating dependencies
Resolving dependencies... (21.2s)

The current project's supported Python range (>=3.8) is not compatible with some of the required packages Python requirement:
  - rdflib requires Python >=3.8.1,<4.0.0, so it will not be satisfied for Python >=3.8,<3.8.1 || >=4.0.0
  - rdflib requires Python >=3.7,<4.0, so it will not be satisfied for Python >=4.0

Because no versions of rdflib match >6.3.2,<7.0.0 || >7.0.0
 and rdflib (6.3.2) requires Python >=3.7,<4.0, rdflib is forbidden.
And because rdflib (7.0.0) requires Python >=3.8.1,<4.0.0, rdflib is forbidden.
Because no versions of rdfpandas match >1.1.6
 and rdfpandas (1.1.6) depends on rdflib (>=6.3.2), rdfpandas (>=1.1.6) requires rdflib (>=6.3.2).
Thus, rdfpandas is forbidden.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties

    For rdflib, a possible solution would be to set the `python` property to ">=3.8.1,<4.0.0"
    For rdflib, a possible solution would be to set the `python` property to ">=3.8,<4.0"

So it seems rdfpandas (I now got 1.1.16) upgraded to a newer version of rdflib, which in turn needs me to exclude python version 4. Now I can also get pandas 2. Numpy (which I used in the same project) had a similar problem, I had to set the minimum python version to >= 3.9. Since I use nothing older than 3.11 I set it to >=3.11,<4. In the end I get rdflib 7 and pandas 2.2.2 and all the dependency problems are solved.
