Hi, I just test your plugin, until I start the 7th step... The log write this:

Hi, did you launch QGIS with GRASS ? For instance my launcher is called "QGIS Desktop 3.10.3 with GRASS 7.8.1".

You can otherwise configure GRASS repository in QGIS parameters.

Hi, I was able to configure GRASS (with this link). But now I have this:

I try on MAC and PC, with Qgis 3.10 and Grass 7... Always the same error!?! I have no "strange character" like _éà-__ for exemple. Even in the attribute of my layers.

Thank you for your help!

As information, I also tested with your sample (Bousquet), and I have the same kind of error:

Hi, What is your exact version and how did you install QGIS (OSGEO or direct installer) ? This issue already happened, it is caused by QGIS gdal:rastercalculator wrapper on some versions, I haven't got the whole picture yet (same error than issue #7).

Best regards, Mathieu

katagen commented 4 years ago

I installed with OSGEO... I have LTM version! image

MathieuChailloux commented 4 years ago

Still hard to find the source of this tricky bug as I can't reproduce it.

I got it working with several versions including last LTR

2020-03-31_09h53_17

Could you try to :

  1. Launch gdal:rastercalculator from toolbox on a raster layer (to check error comes from here)
  2. Check that last LTR version is well installed (3.10.4)
  3. Uninstall all QGIS versions, download OSGEO installer (even if already downloaded), and reinstall it (by the way you can install launcher with grass configured by selecting package qgis-ltr-grass-plugin7)

If needed, you can send me your file and I will launch last step but this is not a sustainable solution.

Best regards, Mathieu

katagen commented 4 years ago

OK, I re-install everything, with the last version of QGIS (non-LTR)... and it works?!? I don't know why?!? Perhaps due to a problem with python-core? See this

MathieuChailloux commented 4 years ago

This other issue was caused by buggy QGIS installers (see issue #6). This one is specific to rastercalculator and I haven't really figured it out...

So this is OK on your side ? I will close this issue and open a new one for rastercalculator error.

katagen commented 4 years ago

Yes, now it's OK for me! Thanks for everything!
