Nettet21. When using PCA in sklearn, it's easy to get out the components: from sklearn import decomposition pca = decomposition.PCA (n_components=n_components) pca_data = pca.fit (input_data) pca_components = pca.components_. But I can't for the life of me figure out how to get the components out of LDA, as there is no components_ attribute.
