basic_usage IPython notebook kills the kernel

[petebachant]

Using the newest stable versions of Python 3.4, IPython from the Conda repositories, attempting to run all cells in basic_usage.ipynb kills the kernel. Top level tests.py script seems to run fine, though there is no output.

I can't reproduce this. Here's what I have:

@chichi-G:~/repos/pyJHTDB/examples$ ipython --version 2.3.1 @chichi-G:~/repos/pyJHTDB/examples$ python --version Python 3.4.0 @chichi-G:~/repos/pyJHTDB/examples$ ipython notebook --version 2.3.1

What's the ipython version you're using?

Best, Chichi L

I am running IPython 3.0.0.

[chichilalescu]

I just upgraded ipython through pip, it's now at 3.0.0. basic_usage.ipynb still works fine though. Could you show me the full output from the server? I'm not sure how you're loading the notebook now, but please open it from a console, with "ipython notebook basic_usage.ipynb". That's gonna show a whole bunch of output, hopefully there's some error message in there.

That is how I was launching it before. Here's my output after trying to run all cells:

Something is apparently going wrong with the auth token?

[chichilalescu]

Yes, you're apparently using the default authorization token. If you already have your own authorization token, please place it in .config/JHTDB in your home folder. This folder should have already been created.

The "Request size too large (16384 > 4096)" is the error I needed to see.

Apparently, I do have to have a smaller request by default in this notebook, so the picture is going to be ugly...

Going to close this since it works with a proper auth token.
