uncertainties fails on python 3.6

[BishopWolf]

I have reported this bug here

Basically, the issue is caused by literal python@2 strings not valid for python@3 representation in the uncertainties package, also there are a lot of python@2-isms like iteritems for arrays.

The problem does not lie with the source code of uncertainties but with the installation process.

I am keeping this open, but fixing the problem should start with lmfit/lmfit-py#605.

I found this read very useful and instructing

I'm reopening this because the latest version with a wheel is not getting installed properly. I'll work on this later.

The problem with the test build is that you are still using eggs instead of wheels. And when installing from a test docker environment:

Thanks for moving this forward 🙏

Version 3.1.3 now has a wheel,

In fact, wheels are expected to have the .whl extension

You could look at this project for an example of project releasing wheels. See https://github.com/amueller/word_cloud

The link to 3.1.3 (which I removed) pointed to version 3.1.2, which doesn't have any wheel. I removed the link in the messages above. The current GitHub version does have a wheel (for Python 3 at least). However, it doesn't install properly yet. I'll have another look.

Version 3.1.4 on PyPI has universal wheels.

This would solve this issue (but the original issue was closed because they dropped Python 2 support), so I'm closing this.
