0.18 conda-forge Package Broken

[ibrummel]

In the 0.18 version of schemdraw that is available from conda-forge, instantiation of elements is broken. Instantiating any element subclasssed from Element will throw an attribute error due to the following line from Element.__init__():

self._userlabels: list[Label] = self._userlabels if self._userlabels else []

This code is not included in the version distributed by PyPI and is instead replaced by:

self._userlabels: list[Label] = []

which obviously works just fine.

I could not find a way to verify if @cdelker is the maintainer of the conda-forge package, but thought I would let you know in case you have access to change this.

Cheers,

Ian

I don't maintain the conda-forge package for schemdraw - perhaps @dkozel could help?

I wasn't able to reproduce this in a clean conda environment (both Python 3.12 and 3.8 on Linux) though. It's odd since the line

self._userlabels: list[Label] = []

has been around since schemdraw v0.9, and I don't think it's ever looked like the one that's broken from what I can tell. I'm not able to check on Windows or Mac at the moment.

[ibrummel]

Thanks for looking into that. I am not sure where it came from either. I failed to mention that I tried with a clean Conda/Python 3.12 environment in Windows 11 and was able to replicate this behavior, so I don't think it was unique to my other environment setup/package list.

The following packages were installed as part of generating the environment for me:

Thanks for tagging me. The conda-forge release directly uses the PyPi upstream code. https://github.com/conda-forge/schemdraw-feedstock/blob/main/recipe/meta.yaml#L8-L10

0.18 has been using this tarball: https://pypi.io/packages/source/s/schemdraw/schemdraw-0.18.tar.gz

I just checked the conda-forge package file for 0.18 and it has the correct line of code in it: https://anaconda.org/conda-forge/schemdraw/0.18/download/noarch/schemdraw-0.18-pyhd8ed1ab_0.conda

I've just updated to 0.19, thanks for the release Collin, and it is now available on conda-forge. https://anaconda.org/conda-forge/schemdraw https://anaconda.org/conda-forge/schemdraw/files

@ibrummel I think there must be some contamination of your system. Multiple installations from different python environments? I know my Windows 11 system is currently a mess of at least five different Python ecosystems which occasionally overlap and create problems.

[ibrummel]

@dkozel Thank you for checking into this. I guess it must be specific to my system but I am not sure what would be generating the issues. Although the only python installations that I have on my system are Conda environments, Conda can sure be obtuse sometimes and break in strange ways.

In any case, if the issue is system specific and you all aren't having issues, I am going to mark this closed, and maybe I will try totally wiping out my Conda installation and reinstalling everything.

Cheers!

[dkozel]

Let me know if you aren't able to get this working with the new release and possibly a new conda install. I'm tied up for the next week, but can do a clean test locally after the 12th.

[ibrummel]

I went ahead and fully wiped my Anaconda install yesterday and reinstalled both the 0.18 and 0.19 releases with success. I am at a loss as to what I had done previously to cause the issue but it looks like it was definitely some sort of overlap from previous work/other installations. Definitely on my end, I just thought it was coming from conda-forge because I had generated a fresh environment and re-installed shemdraw to test.
