RecursionError during start #54

Closed Marwe closed 5 years ago

Marwe commented 5 years ago

Currently the plugin does not load here in my QGIS, due to a RecursionError. Does anybody have an idea what could be wrong? Is it a config issue or dependencies? Maybe I am missing something.

Error log example is attached scp_recursion_load_error.txt

Hello, please try to uninstall QGIS and install it again

Marwe commented 5 years ago

Thanks, but I am on Linux here and install qgis from packages, so there is not too much to be different after a reinstall (That may vary on Windows/other hosts). Did it anyway and found no change, still the same error.

Oops, a reinstall of the SCP plugin now crashes qgis, log/stacktrace on commandline looks identical. SIGABRT in Py_FatalError() seems not to be catched/try-excepted by Extension module. After the crashed install the SCP plugin is installed (and throws the known error, caught in a window at startup).

Any other idea how to debug this?

So much thanks for this great piece of software!

You are very welcome. Unfortunately I think it is an issue related to QGIS package. Can you try to install a different QGIS version?

Marwe commented 5 years ago

What version would be required, < 3.x (2.18) or > 3.4? Unfortunately, on Linux one cannot install different Versions in parallel easily, since there are certain dependencies for each version installed, and you cannot have those parallel in different versions. I am looking into running it virtualised (tried a docker instance, but might need a full install for extensions). TBD...

Just tried a fresh install of QGIS 3.4.5 on Ubuntu 18 (bionic, with ubuntugis-unstable), 2.18 is history anyway: End of life notice: QGIS 2.18 LTR.

All fine there, so I might need to look into some of my (python) dependencies on my ubuntu 16...

Thank you for your feedback. Yes, QGIS issues are generally related to dependencies for Linux.

Marwe commented 5 years ago

Just for information, there are no issues on a fresh install on QGIS 3.4 in Ubuntu xenial (16.04) as well. I tested this via virtualbox. So this issue can be closed, I need to look into my system.

Thanks for your time and the great work!
