After reflection, I think that it's related with gdal (as you were saying). Even if i can do things like gdalinfo, executing a Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/osgeo/__init__.py", line 30, in swig_import_helper
return importlib.import_module(mname)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

ModuleNotFoundError: No module named 'osgeo._gdal'So it's not eoreader's fault ! |

Hey,
I'm trying to read a Sentinel-1 product with this code :
But i get this error message :
Do you have an idea ?
PS : My eoreader version is : '0.22.1'
