cross_val_score using Pipeline does nothing, may be a Pipeline issue?

[jeromemassot]

Dear Data-Scientist, when I run this jupyter notebook in Windows 10, using latest Anaconda distribution, everything is ok until I reach the cell 32 where the cross_val_score function is called using the pipeline previously defined. Nothing happens. The problem may be related to the pipeline because any other cell below referring to the pipeline produces nothing. Thanks for your feedback. Best regards Jerome
