param dependency out-of-date?

[patricktokeeffe]

I experienced problems using hvPlot versions 0.8.0, 0.8.1 and 0.8.2 and the resolution was to manually update the param module to version 1.12.0. Seems like dependency version is out-of-date:

https://github.com/holoviz/hvplot/blob/main/pyproject.toml:

[build-system]
requires = [
    "param >=1.7.0",
    "pyct >=0.4.4",
    "setuptools >=30.3.0"
]

Description of expected behavior and the observed behavior

My system is older but I wanted to try out the data explorer. I upgraded to the minimum version specified in the documentation

The Explorer has been added to hvPlot in version 0.8.0, and improved and documented in version 0.8.1. [...]

pip install hvplot==0.8.0

This resulted in an AttributeError. So I upgraded to 0.8.1 instead and received a completely different error.

pip install hvplot==0.8.1

So then I upgraded to the latest version, but I continue to receive a strange error.

pip install hvplot --upgrade

However, searching online turned up this holoviz Discourse comment, which had the resolution: update param to 1.12.0.

I progressively tried each of the major release version of param: 1.11.0, 1.11.1, 1.12.0 and determined 1.12.0 is the minimum required.

Complete, minimal, self-contained example code that reproduces the issue

Hi @patricktokeeffe ! Thanks for this nice bug report, appreciate the work you put in there 👍

You're right, the minimum version of Param should be 1.12.0. The error message is not quite right though, you are seeing this error as depends has now a on_init argument that is used in some places by hvPlot, older versions of Param don't like that much.

I have seen that you attempted to make a Pull Request. However, you seem to have pointed it to your own fork rather than to this repository. On the image below, it shouldn't be into main but instead into holoviz:main. You may have to close your PR and reopen it to target it to this repository (I'm not sure :) ).

Also your PR is updating the build dependencies, while it should update the runtime dependencies. Let me give you some more context. Param is one of the build dependencies as it has a version module that is used to set the package version from git tags. This is similar to projects like setuptools-scm. No code is executed while building Param, so no change is required wrt the build dependencies. However we want to make sure that when you install hvPlot the right version of Param is installed. For that we have to make sure the runtime dependencies are well defined, these are the packages declared here:

hvplot/setup.py

Lines 30 to 38 in 5129d1f

	install_requires = [
	'bokeh >=1.0.0',
	'colorcet >=2',
	'holoviews >=1.11.0',
	'pandas',
	'numpy>=1.15',
	'packaging',
	'panel >=0.11.0',
	]

As you can see Param is not in this list, which is an oversight as it is effectively a direct dependency of hvPlot (it gets anyway installed because it's a dependency of Panel and HoloViews). So to fix this issue you would need to add "param >=1.12.0" to that list.

Let us know if you are still interested in fixing that :)
