I just reinstalled everything to C: in order to decrease the path length of the data structure. When executing the L2A_Process of sen2cor from the command line I get some kind of parsing error:
I had the same error, not really looked into the cause of this problem, but I just copied the cfg folder from
anaconda2/lib/site-packages/sen2cor-2.2.1-py2.7.egg/sen2cor/ to it’s parent folder.
This will fix the problem that it won’t find the L2A_GIPP.xml file (and probably other files which are in the cfg folder)
