Hello,

When executing the python code block

  #+begin_src python :session python1
    import numpy as np
  #+end_src

I get this error in my python buffer

  Python 3.5.1 |Anaconda 2.5.0 (64-bit)| (default, Dec  7 2015, 11:16:01)
  [GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux
  Type "help", "copyright", "credits" or "license" for more information.
  >>> >>> >>> import numpy as np
  >>>
  open('/tmp/babel-5320QCO/python-5320y31', 'w').write(str(_))


  'org_babel_python_eoe'
  >>> >>> Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  NameError: name '_' is not defined
  >>> >>> >>> 'org_babel_python_eoe'
  >>>

However, the following code block does not give an error:

  #+begin_src python :session python2
    import numpy as np
    1
  #+end_src


Thanks,

Paul

Sorry for the delayed response.  As I just mentioned in another thread,
ob-python sessions have longstanding issues:
