How did I find 'opendrift_landmask_data'? It's missing

There seem to be some problem with your installation. Did you follow this recipe? https://opendrift.github.io/install.html And did you remember to activate the opendrift environment?

It could also be that you need to update your local environment with:

conda env update -f environment.yml

I installed it according to the instructions using git cloning and conda, and I have updated the environment but it still have the same issue. Fortunately I can resolve it with manual cloning from https://github.com/OpenDrift/opendrift-landmask-data master and modified some path. It is working now. This is great, I'm new on this thing, can I make this model with my own dataset? and how I setting the script or configuration? Thank you

Ok, I am not sure why this was necessary, but good that it works at last.

To get started, the best is to read through the turtorial, and study and modify the example scripts: https://opendrift.github.io/tutorial.html https://opendrift.github.io/gallery/index.html
