Now, in order to teach jupyter notebook use I would like to include just the same code as in a python snippet in an ipython snippet. However ipython blocks don't work in my set up and I could not figure out which dependency or config line I might need to add in order to do this properly (and scimax also creates errors, but since I have my own config running I thought ipython might already do the job). The ipython snippet I used is: #+BEGIN_SRC ipython :session :results raw drawer %matplotlib inline import matplotlib.pyplot as plt import numpy as np #+END_SRC The error message is: Traceback (most recent call last): File "/home/username/.emacs.d/elpa/ob-ipython-20180224.953/client.py", line 60, in c = create_client(args.conn_file) File "/home/username/.emacs.d/elpa/ob-ipython-20180224.953/client.py", line 43, in create_client cf = find_connection_file('emacs-' + name) File "/usr/lib/python3.6/site-packages/jupyter_client/connect.py", line 218, in find_connection_file raise IOError("Could not find %r in %r" % (filename, path)) OSError: Could not find 'emacs-default' in ['.', '/run/user/1000/jupyter'] Maybe I do not need ipython anyway. What works are python code snippets like the following one. Minted exports both, code and results and they are both displayed in the pdf slides/manuscript (using lualatex, beamerarticle etc.) #+begin_src python :results output :session :exports both import time time.sleep(3) #+end_src However, then, what does not work properly is several code blocks in one session, e.g. (1) #+begin_src python :results output :session :exports both import pandas as pd import numpy as np import matplotlib.pyplot as plt import datetime as dt import seaborn as sns sns.set(style="darkgrid") #+end_src (2) #+begin_src python :results output :session :exports both df = pd.read_csv('./household_data_1min_singleindex.csv') #+end_src (3) #+begin_src python :results output :session :exports both zeit=df.utc_timestamp.apply(lambda x: dt.datetime.strptime(x, "%Y-%m-%dT%H:%M:%SZ")) #+end_src (4) #+begin_src python :results file :session :var matplot_lib_filename=(org-babel-temp-file "figu" ".png"),fontsize=fs :exports both plt.rcParams.update({'font.size':fontsize}) rcParams.update({'figure.autolayout': True}) plt.plot(zeit,df.DE_KN_residential2_washing_machine) plt.savefig(matplot_lib_filename) matplot_lib_filename #+end_src I do not like the fact that plt.rcParams.update and other lines that jupyter does not need get exported - is there a simple way to exclude certain lines from export? And I do get in serious trouble when I add a second data set (another csv) and do further analysis steps - all graphics then look the same and bad and do not represent the actual result of the code block. It seems that all get the same wrong name and then at each graphics location this same png gets displayed. So, maybe there is a good tutorial on using sessions in ob-python or some other hint that I could use? Is there a way to restart the (python) kernel with some header message in the src block? Thank you very much, Cheers, J. May
