Hello,

I’m new to EOlearn. I want to import the neccessary packages in order to work with EOlearn but I get import error:

from eolearn.core import EOTask, EOPatch, LinearWorkflow, FeatureType



# # We'll use Sentinel-2 imagery (Level-1C) provided through Sentinel Hub

# # If you don't know what `Level 1C` means, don't worry. It doesn't matter.



from eolearn.io import SentinelHubInputTask



from eolearn.mask import AddValidDataMaskTask

ImportError: libGL.so.1: cannot open shared object file: No such file or directory’

I do have the library cv2 installed, so I don’t know why it raise this error. What else could cause this error?
