In ArcGIS Pro versions 3.5.5 and 3.6, the Train ISO Cluster Classifier tool and the ISO Cluster classifier from Classification Tools return the “004096: There are only data samples to cluster, which is not enough.” error message when the Windows display language is set to Czech.

解决办法

1. Change the Windows display language to English to successfully run both tools.
2. Use the ISO Cluster Unsupervised Classification tool in the Spatial Analyst toolbox.
3. The Train ISO Cluster Classifier has an optional parameter > Input Raster. If a DEM is provided, the tool runs successfully even with the Windows display language set to Czech.
