Hi Manu,
Tensorflow supports Tif and GeoTif in both formats. Unet is good for land cover classification and Mark rcnn is good to got detecting building. If it's a single object you can try SSD as well.
Getting the error in Labeling the objects, exporting the chips, and detecting objects are mainly depending on python libraries. Please check the libraries and it's the version which you installed. If the version is not matches to the available one try to downgrade or upgrade to the relevant version and try it.
Here is few tips, if you wish to run outside of ArcGIS Pro:
- Download and install the minconda
- Create new env ‘conda create -n arcgis -c esri arcgis_learn python=3.7.’
- Activate the arcgis by using ‘conda activate arcgis’
- Optional: if require pip install the relevant libraries
Once your env is get activated you can start to train the model.
Thanks
