Problem with python source block

Problem with python source block

[Doyley, Marvin M.]

Hi there,

When I run the following code I get an error, does anybody know how to fix this

I am using the latest version of org-mode.

Thanks,
M


#+BEGIN_SRC python :results file
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
x = np.random.rand(100)
y= np.cos(x)
plt.plot(x,y)
plt.savefig('test.png')
return 'test.png'
#+END_SRC

#+RESULTS:
[[file:  File "Org SRC", line 8
    return 'test.png'
    ^
SyntaxError: 'return' outside function
]]

Hi,

For what it's worth, I cannot reproduce it on Org mode version 9.1.13
(release_9.1.13-763-g2621db) with -Q; the file is properly produced.

I get the same error if I add the `session' header argument, maybe it is
set elsewhere?

Hope it helps.

I get a reproduction of your error outside of Emacs and Org Mode.

Adapting an example from the list’s archive, the following works.

#+BEGIN_SRC elisp :results none
  (org-babel-do-load-languages
   'org-babel-load-languages
   '((python . t)))
#+END_SRC

#+BEGIN_SRC python :results output
  a = 5
  b = 16
  print(a + b)

#+END_SRC

#+RESULTS:
: 21

Hi there,

The problem seem to be cause by scimax-org-babel-python.el.
When I disable this works fine, but doing this disables asynchronous execution.

John do you have any suggestions what is going on ?

Cheers,
M

The default for :results in scimax is output. You need to specify that you
want the value for your block.

This worked for me.

#+BEGIN_SRC python :results value file
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
x = np.random.rand(100)
y= np.cos(x)
plt.plot(x,y)
plt.savefig('test.png')
return 'test.png'
#+END_SRC
