AttributeError: 'GeoTiff' object has no attribute 'get_coords'

[Qayam123]

I am simply trying to convert local ccordinates in a tiff image to latitude and longitude using the code snippet:
from geotiff import GeoTiff
geo_tiff = GeoTiff('./SAR_imgs/VH_dB.tif')
print(geo_tiff.get_coords(996,163))

it's working perfectly fine in Jupyter notebook , however throwing error in terminal . Anyone help me troubleshoot this
