Sample code does not run

hooger commented 8 years ago

Hello! I have a problem running a sample code in org-mode, using ob-ipython. When I run it, it gives fatal error. It runs perfectly from a browser. System is Debian 8, up-to-date, emacs version is 24.4.1 ob-ipython version is 20160703.639 jupyter is not installed, as it is not in the official repo, ipython is used instead. Version: 2.3.0-2 python-tornado version is: 3.2.2-1.1 Any idea?

Sample code is:

#+BEGIN_SRC ipython :session mysession
%matplotlib inline
import matplotlib.pyplot as plt
import numpy as np
t = np.arange(0.0, 2.0, 0.01)
s = np.sin(2*np.pi*t)
plt.plot(t, s)
plt.show()
#+END_SRC

Message is the following:

Evaluate this ipython code block on your system? (y or n) y
executing Ipython code block...
Contacting host: localhost:8888
ob-ipython--dump-error: There was a fatal error trying to process the request. See "ob-ipython-debug"

Ipython says that:

I think your dependencies are all dated. I'd suggest either upgrading to latest jupyter stuff (4.x anyway - 5 may not work yet) or you could try the branch of ob-ipython ipython3. I deliberately kept this around for older dependencies. You'll need to check this out and install manually though.

Thank you for the answer (and sorry for the slow reply :( ). I upgraded jupyter and the necessary libraries from pip and it worked. I haven't tested your branch.
