Re: [Qgis-user] Adding python package dependencies to a QGIS plugin
Hey Robert :) tl;dr: Check this out -> https://lists.osgeo.org/pipermail/qgis-developer/2022-April/064661.html This question has been asked many times but because mailing lists are ... special ... the discussions around it are spread across tens of messages, accessible via arcane and hard-to-navigate websites that might not even be indexed nicely by search engines. Anyways, just some days ago this was discussed once again on the qgis-developer list: https://lists.osgeo.org/pipermail/qgis-developer/2022-April/064661.html In this case you are lucky that the discussion has not gone into another month yet so you should be able to click on "Next message (by thread)" to see the discussion bit-by-bit. I'd recommend checking the threaded view too though https://lists.osgeo.org/pipermail/qgis-developer/2022-April/thread.html because someone might have decided to branch off into another thread with a different mail subject. If you want to reply, you cannot use your account on the qgis-user mailing list but have to register once again. No, I don't like mailing lists, thanks for asking! >:( ;) Cheers, Hannes Am 19.04.22 um 23:08 schrieb nagyrobi_r--- via Qgis-user: Hei everybody!

Hi, if you would ask me, I'd advice: - small (python) modules? Add a copy in your plugin - others: instruct users to install them (depending on OS this is more or less difficult) Your methods all need some 'magic' to happen, which will probably break, but feel free to try.
