Chuck,
Thanks very much for your response. I didn't know about those options.
When I use C-c C-v C-i, I get the following:
Lang: python
Properties:
:header-args nil
:header-args:python nil
Header Arguments:
:cache no
:exports code
:hlines no
:noweb no
:results output replace
:session none
:tangle no
And C-c C-v C-v, shows that the import statements in the header do not
get expanded into the code block.
So I am obviously doing something wrong. There appear to be no typos or
misspellings and the org file containing the coded is exactly this:
* Test of prologue header
:PROPERTIES:
:header-args:python+: :prologue "import numpy as np; import os"
:END:
#+BEGIN_SRC python :results output
print(np.__version__)
#+END_SRC
#+RESULTS:
My init file has no org babel header arguments defined.
I am using C-c C-v C-b or C-c C-v C-s to evaluate and I get
"Code block produced no output." in the mini-buffer.
If I use C-c C-c directly on the code block itself I get:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'np' is not defined
Is there something else I need to do to get babel to recognize the
header-args?
Thanks

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 don't really want a stateful session (nor does ob-racket support sessions) so I essentially want the equivalent of automatically including it everywhere so I don't have to type it out all the time (and have it screw up syntax coloring/indentation).
