ValueError with certain input file

[lodersky]

Running the code with a certain input file (attached) gives the following error message:
Traceback (most recent call last):

  File ".../geoclustering/code/runme.py", line 18, in <module>
    k_means_clustering(paths, param)
  File "...\geoclustering\code\lib\kmeans_functions.py", line 340, in k_means_clustering
    optimum_no_of_clusters_for_raster = identify_opt_number_of_clusters(paths, param, i, size_of_raster, std_of_raster)
  File "...\geoclustering\code\lib\kmeans_functions.py", line 135, in identify_opt_number_of_clusters
    optimum_no_of_clusters_for_raster = int(np.ceil(group_by_part.loc[part, "share"] * maximum_no_of_clusters))
ValueError: cannot convert float NaN to integer

Would be helpful to get feedback on the error. The example files of the workshop are working fine.

Grundwassertemperatur.zip

For that, we need to save the TIF files (at the cuting stage) as float rasters.
