Hi @Ameliecc,

what python version are you using? What version of mistree is installed on your device?

I was able to get it to install by installing from source, thank you for the recent update :)

I also have this problem when i run example_tree.py.so how can i fix it?

I am getting a similar issue with python 3.9 numpy version 1.26.0, on windows 11 and version of mistree===1.2.1
(The reason i am specifying numpy version is because open3d crashes for numpy version 2.x)

Okay the issue was with the pure python branch of the package mistree, if you've installed the pure python branch, the module name is mistree_pp not mistree.
