installation & dependency issues

[mattiasarro]

Using Python 3.8.0, pip install idom[stable]==0.28.0 has dependency conflicts for the following packages.

ERROR: requests 2.25.1 has requirement idna<3,>=2.5, but you'll have idna 3.2 which is incompatible.
ERROR: httpcore 0.3.0 has requirement chardet==3.*, but you'll have chardet 4.0.0 which is incompatible.
ERROR: httpcore 0.3.0 has requirement idna==2.*, but you'll have idna 3.2 which is incompatible.
ERROR: sanic-plugin-toolkit 1.0.1 has requirement sanic<22,>=21.3.1, but you'll have sanic 19.9.0 which is incompatible.
ERROR: sanic-cors 1.0.0 has requirement sanic<22,>=21.3.1, but you'll have sanic 19.9.0 which is incompatible.

What's a good Python version to use and sequence of pip install commands to get hello world examples working?

I think if you upgrade pip these problems might go away:

pip install --upgrade pip

Thanks, that helps (tried/works with Python 3.8.0 and 3.8.6). It's a shame the Python requirement is quite high, though. I'm stuck using Python 3.6.9 for now (where max idom version is 0.6.0) since I need to use a TensorFlow Docker image that uses 3.6.9.

[rmorshea]

I don't know when I'd have time to check this out myself, but after the release of IDOM 0.30.0 (in the coming weeks) - I'd be happy to take a contribution that added support for Python 3.6. Chances are most of the issues would be resolvable using 3rd party back-ports of of 3.7+ features. Let me know if that's something you'd be interested in and I can try to help out.

[mattiasarro]

Thanks for the reply. At the moment I would not have the resources to work on that, so I'm instead making a simpler solution (without idom) from scratch.
