Interpolation fail error #47

Closed mbayad33 closed 1 year ago

mbayad33 commented 1 year ago

Hello ,

I have tried to ordinary kriging using SmartmapPluging but each time I get this error when I click interpolate:

This error is generated when I select non-linear model (e.g. polynomial). But the plugin works fine with linear model for me.

Could you please help solve this error?

An error has occurred while executing Python code:

numpy.linalg.LinAlgError: Matrix is singular.

Which plugin version are you using? Install the latest version (1.3.2): https://plugins.qgis.org/plugins/Smart_Map/version/1.3.2/ And check again if the error persists.
