PCA_TSNE_bug

[Lina647]

Please Can you help me I have a problem when I tried to execute the examples of clustring when I use PCA in reduced_features such as reduced_features = features_ds.apply(ops.dim.pca(n_dim=2)) I get the following error message: not enough values to unpack (expected 2, got 0) and when I use tsne I get error message as following:
'TSNE' object has no attribute 'embedding_'
