conda VS rez

Python's venv module is officially recommended for creating virtual environments since Python 3.5 comes packaged with your Python installation. While there still are additional older tools available, such as conda and virtualenv, if you are new to virtual environments, it is best to use venv now.

conda's dependency solver solves a harder problem than pip's. This quote alludes to it "Conda will never be as fast as pip, so long as we're doing real environment solves and pip satisfies itself only for the current operation." (from https://github.com/conda/conda/issues/7239). Thus mamba was created to improve performance and now conda is bringing in that performance boost.

The other challenge I ran into sometimes was that if I was running a lower memory/storage Codespace instance, when I tried to use Conda from the command line to modify environments, the process would be killed after a few seconds. This turns out to be related to some performance issues Conda has that make it consume a lot of memory when trying to work with the conda-forge installation channel. You can always then just increase the size of the Codespace your are working with (just go to your Codespaces list and use the triple dots to change the settings for a Codespace).

It's worth noting that [ana]conda isn't even fully compatible yet with 3.11 (you can use it to create 3.11 environments--and you really should rather than waiting on relying on the system python--but conda itself can only run on 3.10.

It took some time but as great Christmas present Miniconda was finally released with Python 3.10!

The September update broke it.

According to this this issue is high on their priority list (whatever that means).

What alternatives are there to rez?

To sum up the previous post, I currently use and like (rez)[https://github.com/AcademySoftwareFoundation/rez], but I am wondering if there is something better out there with the same idea of rez, i.e.

I am looking for a quick and easy to use tool to manage version control of different packages. Mainly on Linux but multi platform support would be great. I have found and used rez and I quite like it. I find it lightweight and I only barely need to use it if I wanted to, i.e. I could link to all the packages installed locally by myself. However, if there is something out there that is more widely adopted and would have lifetime support then I would prefer to use that.

Great stuff! Will check it out. https://github.com/nerdvegas/rez

It's mainly for the purpose of taking these RPMs and converting them to a slightly different package manager (rez). Ideally, any found solution would be able to work with older versions as a result. Though I'm learning online that yum, yumdownloader, and other tools seem to restrict output based on data about the user's host OS
