This use of :prologue appeared to me to be very useful.  But for some 
reason when I try it out it does not work for me.  I just get a message 
that the code block produced no output and that 'np' is not defined.  
Just to check, when I put the import statements directly within my code 
block it works fine.

I am running:  Org mode version 9.3.7 (9.3.7-16-g521d7f-elpa

Any idea what I'm doing wrong?
