Description
I wrote a simple python code of printing the elevation values of the NOAA DEM raster file (a DEM raster file with 6.5 million cells in it) in the Python Editor provided in QGIS3 (using the PyQGIS library).
I ran the code by using the different raster file with a small number of raster cells, but it still crashed when running the code.
