Relax dependency requirements? about asilib HOT 3 CLOSED

Hi @jameswilburlewis,

The requirements.txt file specifies the dependencies for the developer environment which I purposefully pinned to exact versions, while the pyproject.toml specifies looser requirements for users. For your PyHC environment, may I suggest that you install asilib via python3 -m pip install asilib, or python3 -m pip install . from in the asilib/ directory.

Please let me know if you run into any trouble installing the package, or if you'd like me to loosen any dependencies in pyproject.toml.

P.S. I plan to attend at least a part of the PyHC summer school, and if necessary I am happy to help out with your examples. Reproducing results from well-known papers is always a joy.

P.S.S. Thank you for the appraise! While asilib has a downloader built-in already, I have not considered using pyspedas as an alternative downloader. Is this the function that handles downloading for all missions that pyspeas supports?

After opening the issue, I did see the looser requirements in pyproject.toml. I asked Shawn Polson to take a look, and he did see some conflicts (he didn't mention what they were, though...) Maybe it's better not to try fitting it into the environment at this late date...we can revisit the issue after summer school is over. I will still generate a few movies for my presentation and mention how I did them with asilib; we just won't use that package for any of the live demos under the PyHC environment. We're focusing on the March 24, 2023 event -- there were clear skies over Canada that morning, and some very nice imagery from several of the THEMIS ASI sites!

Yes, download.py is the main routine PySPEDAS uses for downloading data. There's a load routine themis.ground.ask() for loading keograms; I should probably add a few more routines for loading the THEMIS ASI data, maybe also the REGO or T-rex datasets. Then all you'd have to do is call the top level load routines, and pull the data arrays out of the returned tplot variables, rather than writing code do call download() then doing your own cdf processing....

I'm working on implementing field line tracing in pyspedas using the geopack package. That might come in handy for animating conjunctions using magnetic foot points.

I'll go ahead and close this issue....I'll be sure to let you know when I've added some more ASI support to pyspedas. Meanwhile, if you have future updates for asilib, I'd be happy to help test them!

Would you mind asking Shawn to share what the conflicts are? I can experiment with relaxing the dependencies. And do you see an immediate benefit to merging asilib into PyHC before the summer school? I've been meaning to do it, and I can commit some time now to the merge.

I'll be happy to utilize your field line tracing code so please keep me updated. And we should chat later about how to download the data. To my knowledge the REGO and TREx data can only be accessed from Calgary's site which has a non-trivial folder structure. Specifically, one of the parent folders of the data is, for example, kapu_themis21/, where the "21" has to be deduced using regular expressions on the hrefs.
