I'm using the ArcGIS Python 2.7 interpreter in my PyCharm as I need several algorithms of the ArcPy package. However, I am having trouble with the RegionGroup of ArcGIS 10.7, as it sometimes crashes my loop with the exit code -1073741819 (0xC0000005).
I have already asked a question on how to fix that (Process finished with exit code -1073741819 (0xC0000005) from RegionGroup (ArcGIS 10.7)), but I am assuming that it is rather difficult to solve (at least Google seems to think so).
I need to stay with the 2.7 Python in my PyCharm, but maybe there are some alternatives to region group a raster?

    When it is about raster data, I always think in GRASS GIS, which has powerfull tools for python scripts, but I am of little help beside this vague idea.

  • I also thought about GRASS, but wouldn't I have to use a different python interpreter for this than the ArcGIS one? Commented Jan 23, 2020 at 10:54
  • Good question. I have not worked with pygrass at all. Have you seen this gis.stackexchange.com/questions/203310/…? it might help you to answer the previous question
