RuntimeError: maximum recursion depth exceeded about lancet HOT 10 CLOSED

Never mind, it seems to be the pip-installed param package that is incompatible with lancet HEAD. Now works with param installed from the git repo.

Thanks. We need to make a new PyPI release of param so that pip will work, but haven't had a chance yet.

I just ran into the same problem and almost submitted another bug report but fortunately stumbled upon this closed issue first. Would it be possible to make another PyPI release of param at some point, or at least add a comment on the Lancet webpage that param should be installed from github? Many thanks!

Sigh. For us to do a decent job of packaging, we need some volunteers! But yes, we need to move that higher up in the priority list...

from lancet.

Apologies if this is a naive question, but since I have never uploaded a package on PyPI I'm wondering what's required to do it? Looking at https://docs.python.org/2/distutils/packageindex.html I would have thought that it's more or less a (semi-)automatic process. But there doesn't seem to be a setup.py file in the Lancet codebase, so am I guessing correctly that part of the task is to set one up? If there is something I can do to help that doesn't require too much time then please let me know! (Although it'll be a couple of weeks before I can look into it.) But to be honest I hestitate to step forward as a volunteer unless I know that Lancet is the right tool for my workflow.

The main problem is that I forget how to do it in between releases. :-) I don't think Lancet has been released to PyPI (Jean-Luc Stevens would be in charge of that), but here we need Param to be re-released, not Lancet. Param does have a setup.py file, but we have to remember how to do the release, look over the diffs since the last release to see if there are any changes that affect compatibility, then document those somewhere. Probably not easy for us to delegate at this point, as at least some of those steps really have to be taken by an experienced developer on the project. We'll do it!

Ok. Thanks a lot for the explanation and for uploading a new release! (No rush, I just thought I'd put a comment here because I'm likely not to be the only person to encounter this issue.)

from lancet.

The easy part of the packaging process:

$ python setup.py sdist

To upload to pypi as well, it's something like:

$ python setup.py sdist upload

But yes, the time-consuming part is to review (and possibly deal with) code changes and issues opened since the last release. From git describe it looks like there have been 46 commits since the previous release.

(Just to clarify, I'm talking about param.)

Hi

Sorry for not responding to this issue till now! A new version of param has just been released on PyPI which seems to resolve this issue.

pip install  --upgrade param

Should hopefully do the trick!

Awesome, thanks a lot. I'm currently travelling and won't be able to try this for another week or so, but I'll give it a shot when I'm back.
