Dear forum
I need yo stack some rasters using pyqgis
This is the code I wrote
import processing
from processing.core.Processing import Processing
from qgis.core import *
parameters = {'INPUT':
'/home/file1.tif;/home/file2.tif;/home/file3.tif;/home/file4.tif', \
'PCT': False, \
'SEPARATE': False, \
'NODATA_INPUT': 0, \
'NODATA_OUTPUT': 0, \
'OPTIONS': "", \
'DATA_TYPE': 5, \
'OUTPUT': '/home/stack.tif'}
processing.run ('gdal:merge', parameters)
but I get this error
Traceback (most recent call last):
File "/usr/lib/python3.7/code.py", line 90, in runcode
exec(code, self.locals)
File "<input>", line 1, in <module>
File "<string>", line 76, in <module>
File "/usr/share/qgis/python/plugins/processing/tools/general.py", line

return Processing.runAlgorithm(algOrName, parameters, onFinish,
feedback, context)
File "/usr/share/qgis/python/plugins/processing/core/Processing.py", line
137, in runAlgorithm
raise QgsProcessingException(msg)
