Sentinel-3 OLCI FUB-CSIRO - failure of plug-in configuration in SNAP (9.0.0)

I’m trying to configure the FUB-CSIRO plug-in in SNAP (version 9.0.0, Python version, Windows OS, with Python 3.6.8, as recommended). However, I’m not able to run it, and the following Error message appears:

“An internal error occurred during the target product initialisation.
Type: RuntimeException
Message: Error in Python interpreter:
Type <class ‘ModuleNotFoundError’>
Value: No module named ‘numpy’
Line: 865
Namespace: module

Could you advice, how could I solve this issue?
Thank you very much.


Your python environment needs numpy installed.
I think the plugin also needs scipy.
For a complete list of python dependencies, you better ask the plugin provider.
You find their contacts at the end of the Readme.

Thank you very much. Your recommendations helped, and I’m able to run the processor in SNAP.
Now I’m trying to perform the processing using GPF Graph, however the process ends with an error (

Fatal Python error: Py_Initialize: unable to load the file system codec
ModuleNotFoundError: No module named ‘encodings’.

I’m adding the .xml file with a code I’m using (
Bandymas.xml (2.7 KB)
Could you help me to understand, which step is the problem?
Thank you very much.

It seems this problem is not really related to the processor or SNAP.
In this stackoverflow thread it is discussed that this is related to the python settings. Two python installation seem to interfere. If you properly set up the environment variables it should work.
