I am using GDAL from osgeo to work on geotif files. I have not figured out out to use the option -a_gt to alter the geotransform and used a systen call instead.

This is my first question in the forum, so please apologize if I’m missing to follow some rules.

I like to convert tif file to pmtiles. According to this: https://github.com/protomaps/PMTiles/blob/main/README.md
I should first create mbtiles and then do conversion to pmtiles but while doing so I receive key err as shown below the code.
