OK that clarifies stuff thanks a million
I did install Anaconda because it was originally recommended. I only used it to run SNAP and sen2cor. If you tell me it is of no use I will happily wipe it off my drive.
I am using SNAP5.0
I ran snappy-conf several time and I had the persistent error similar to this post
with a Java max memory undefined error
I have tried to write to the snappy.ini
[DEFAULT]
snap_home = /usr/local/bin/snap
java_max_mem: 40G
But it would not work, python tells me that this is not a valid path. And of course running snappy-conf wipe snappy.ini
I have tried to export the environment variable before running python and it would not work either.
So I decided to give a go to SNAP 6 since it seems released officially now.
Hopefully I get more success
