PyPOTS

PyPOTS copied to clipboard

Hi! You may have noticed that, when creating a new conda environment from *.yml file, it takes ages to solve package dependencies. I attempt to speed the process up by explicitly defining channel in which to search for a package. I also defined minimal pandas version to be 1.4.1 - the things were weird before that. I also allow for python versions newer than 3.7.13 and I believe you'll find it acceptable.

Please let me know if this is in any way helpful.

Hi Maciej,

Yes, I noticed that building an environment for PyPOTS does take some time. So your PR looks helpful indeed. Thank you for your idea!

But GitHub auto-testing met errors with your PR. Please check it out here.

Yeah, I noticed that so i closed the PR and am working on fixing it :)

Cool. Please reopen your PR when you think it's ready. Then we can run a test to see if your commits can speed up the process of environment building.

If the tests pass, we could probably speed it up a lot by determining possible version range per package, but I guess that would make us conda dependency resolvers :wink:

This commit works fine. You can try to specify the version of each package to see how much it can speed up. 👀

I froze the test env, each package with one version explicitly set. If the time gain is not huge I don't think it is worth testing each dependency and searching for minimal requirements.

The tests failed, i capitulate :sob: :white_flag:

last try with versions that conda found for me with python3.7.13

No worries. I'll give your idea a try by myself when I have time 😃. I add this idea in GitHub Discussion, you can check it out here #8 Many thanks for your suggestion and your efforts ;-)

I'm closing this PR due to the problem has been solved in the latest release v0.0.10. Please feel free to reopen it if anyone meets the same issue again.
