I use QGIS 3.4 with Python 3.7 and I have a warning message when importing Processing like this :
import processing from processing.core.Processing import Processing
Here is the message :
Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working
What is the new way to import it without getting this DeprecationWarning ?
