Installation via Anaconda fails

[iainhallam]

I've got a fresh Anaconda 3 installation (2023.07-2) and I get some syntax errors when trying to install Mesa into it. I'm a Linux admin, rather than Python programmer, so can anyone see what's likely to be the cause, please? I'm on Rocky 8 (clone of Red Hat EL8) and have installed the Anaconda prerequisites using yum.

$ rm -rf /opt/anaconda/3-2023  # Clears all previous installations; I have write permissions on /opt/anaconda

SyntaxError: invalid syntax

There are another 8 of these errors, all at {{cookiecutter.<something>}} strings.

Do let me know if this is the wrong place to ask about this, too!

Do you have to use conda? For now, can you use pip? What if you use Docker inside of Rocky Linux? #1757 for how to do it.

This seems like a bug instead of discussion. The reason is somehow conda doesn't like filenames with {{...}}.

[rht]

There is cookiecutter/cookiecutter#1049. I had thought about renaming the .py files to something else, since technically they are not actual Python files with correct syntax anyway. The issue OP seemed to do this as a workaround. But I think it is a more proper solution.

[rht]

Should be fixed in #1785. @jackiekazil @tpike3 should we release 2.1.2 very soon, since it has accumulated enough fixes?

[tpike3]

Merged and agree we should do another release.

[iainhallam]

That's great news, @rht, thanks. Do you know what sort of timetable a new release would be?

[rht]

Hopefully by the end of this month: #1787 (comment). Only 2 issues left:

• Step index of DataCollector Dataframes are not synchronized between agent and model variables #1768 is not critical and could be skipped
• visualization tutorial: Needs to be updated to reflect the simplified code in #1786 #1792 is a blocker, but is a quick fix. Only few lines of code of change is needed.

[jackiekazil]

Agree

@iainhallam we just released 2.1.2 with the cookiecutter fix. Can you try this again?
