TypeError 'module' object is not callable: when calling Orange.projection.pca

[Garch2017]

Hi,

Can anyone help with the error below when I call the code?

import Orange
iris = Orange.data.Table("iris.tab")
pca = Orange.projection.linear.Pca(iris)
transformed_data = pca(iris)

ERROR:
import Orange
iris = Orange.data.Table("iris.tab")
pca = Orange.projection.pca(iris)
transformed_data = pca(iris)
Traceback (most recent call last):
File "", line 4, in
pca = Orange.projection.pca(iris)
TypeError: 'module' object is not callable

The way this worked for me was:

import Orange
iris = Orange.data.Table("iris.tab")
pca = Orange.projection.pca.PCA()
transformed_data = pca(iris)

However, this is poorly documented and should be explained better. Will fix it.

ajdapretnar, many thanks for your reply.

Oh, sorry. I didn't quite realize this is an Orange2 repo. Instructions might not be the same for Orange2....
