Currently, nested imports do not seem to work: ### 1) ```python In [1]: from sklearn.model_selection import train_test_split In [2]: %load_ext watermark In [3]: %watermark -iv ``` ### 2) and only the current scenario is supported (among other variants): ```python In [4]: import sklearn.model_selection In [5]: %watermark -iv sklearn 0.20.2 ``` It would be nice if we could also get 1) to work.
