No module named `gdal`

When I trying to import MTF Estimator in a fresh installation of QGIS 3.22.1 the plugin manager complains about:

Couldn't load plugin 'mtf_estimator' due to an error when calling its classFactory() method 

ModuleNotFoundError: No module named 'gdal' 
Traceback (most recent call last):

I've replaced import gdal with

try:
    from osgeo import gdal
except ImportError:
    import gdal

in mtf_estimator_algorithm.py

and also the standard import of osr, ogr and gdal in mtf_estimator.py with:

try:
    from osgeo import gdal
except ImportError:
    import gdal

try:
    from osgeo import ogr
except ImportError:
    import ogr

try:
    from osgeo import osr
except ImportError:
    import osr

And it seems to work now.

Please, consider making this a permanent change.

Fixed. Thank you very much for reporting. I've already submitted the updated plugin for approval. It will be available soon.

Feedback about the plugin and/or algorithm will be highly appreciated.
