Error just from adding in the first raster layer

[ahaughan]

Hi, I have just begun using MOLUSCE so apologies for any incorrect terminology or understanding. I am trying to conduct a change detection analysis from a 1995 land cover classification raster to a 2015 raster. I open MOLUSCE and select the 1995 year and get the following error:

Python error: An error has occurred while executing Python code: See message log (Python Error) for more details.

And the message log says this Python code:

2017-12-06T16:19:13 1 Traceback (most recent call last): File "C:/Users/yh800249/.qgis2/python/plugins\molusce\moluscedialog.py", line 215, in setInitialRaster initRaster = Raster(unicode(layer.source()), maskVals=utils.getLayerMaskById(self.initRasterId)) File "C:/Users/yh800249/.qgis2/python/plugins\molusce\algorithms\dataprovider.py", line 54, in init if self.filename: self._read() File "C:/Users/yh800249/.qgis2/python/plugins\molusce\algorithms\dataprovider.py", line 287, in _read self.bands = np.ma.zeros((data.RasterCount,self.geodata['ySize'], self.geodata['xSize']), dtype=float) File "C:\PROGRA~1\QGIS2~1.18\apps\Python27\lib\site-packages\numpy\ma\core.py", line 7887, in call result = self._func.call(*args, **params).view(MaskedArray) MemoryError

Can anyone suggest what I might be doing wrong?

Thanks

MemoryError shows issues with memory. MOLUSCE performs all processing steps in RAM, therefore the error happens if one (or more):

• your computer doesn't have enough memory;
• the rasters are 'big' and don't match free memory; Try to check it, for example try to process a small raster (less pixels and less land-use classes).

Yes it does work with a smaller raster, thank you for the help!
