New releases of python-weka-wrapper

Since Weka 3.9.1 is finally out, ​I released new versions of the python-weka-wrapper library:

​Changelog for both releases:

  • typeconv.double_matrix_to_ndarray no longer assumes a square matrix
  • len(Instances) now returns the number of rows in the dataset (module weka.core.dataset)
  • added method insert_attribute to the Instances class
  • added class method create_relational to the Attribute class
  • upgraded Weka to 3.9.1
​Weka 3.9.1 introduced changes to its package management, so it is recommended to upgrade your packages to the latest version.​
