import olca "no module found" eclipse #31

Open dilull0 opened 2 years ago

dilull0 commented 2 years ago

I am trying to work with openlca using eclipse to automate data updates based on data collected from Excel. When I try to run import olca command from eclipse I get an error saying the "no module found" I have been through every installation guide and cannot figure out how to get this to work. I installed olca-ipc using pip, I copied the libs folder from openlca into the C:\Users*****\openLCA-data-1.4\html\olca-app folder. It still does not work. I am using the most current installation for everything. I have lots of coding experience with VBA, R, and MATLAB, but am new to python.

The olca module comes with olca-ipc.py but it only works in standard Python and communicates with openLCA via an http server (you need to start it in openLCA via Tools > Developer tools > IPC server). The Python scripts that you can run in openLCA run on Jython which is a Python implementation for the Java virtual machine. The olca module does not work there. Instead you directly call the Java API of openLCA with it.

Just to make sure I understand this correctly.

When you go Tools>Developer Tools>Python the code here uses jython jython uses code like from org.openlca.core.database import UnitGroupDao, FlowPropertyDao, CategoryDao, Daos key commands can be found in https://github.com/GreenDelta/olca-modules/tree/master/olca-core/src/main/java/org/openlca/core/model

For IPC Server when written in eclipse or another ide you use olca-ipc.py and the import command should work if I run the code in eclipse.
