Smart Map plugin: error sampling 5000 data points

Question

I'm trying to use the Smart-Map plugin in QGIS to do Kriging. I have about 15,300 data points and I need to sample the data (5,000 points, maximum for Smart-Map right now). But this error appears when trying to sample.

Any idea why? (all data certainly float).

An error has occurred while executing Python code: 

NameError: name 'float32' is not defined 
Traceback (most recent call last):

welcome to the GIS StackExchange.

Do you have any programming knowledge or are you just a Smart-Map user? I faced the same issue months ago and If you have programming knowledge, open the Smart-Map.py file and import numpy.float32 type at the top of the imports

from numpy import float32

It was worked for me. However, if you cannot do this by yourself, I strongly recommend you to open an issue on the Smart-Map GitHub issue page. Below you'll find the link.
