OK, here's where it comes from.
I have a data analysis script, residing in my Documents folder. The script
reads raw data files on a server share. It creates a subfolder "Analysis"
and puts a bunch of tables and plots in that folder. At the end of the
script, I want to:
1. Save a copy of the executed notebook (.ipynb format) in the same
subfolder, and
2. Save an HTML version of it, also in the same subfolder
This should be trivial to do but unfortunately it's not. (It's sad that
such a wonderful tool is so lacking in terms of introspection). I currently
handle those two tasks as follows. To create a copy of the notebook, I use
shutil.copy(nb_path,os.path.join(Save_dir,nb_filename))
To save an HTML copy, I use:
!jupyter nbconvert '$nb_path' --output '$nfname'
Both of those require to know the path of the notebook currently running.
After much googling, I settled on this:
connection_file_path = kernel.get_connection_file()
connection_file = os.path.basename(connection_file_path)
kernel_id = connection_file.split('-', 1)[1].split('.')[0]
sessions = json.load(urllib2.urlopen('http://127.0.0.1:8888/api/sessions'))
for sess in sessions:
if sess['kernel']['id'] == kernel_id:
nb_rel_path = (sess['notebook']['path'])
break
res = !echo ~
nb_path = os.path.join(res[0],nb_rel_path)
This normally works, but the other day I had another server running, so
naturally the second server's port was set to 8889 instead of 8888,
therefore breaking my script.
There are two other problems. Sometimes the saved .ipynb is not complete.
The last few cells are saved without the output. The sure way to save a
complete notebook is to manually hit the Save button, then re-run the cell
with the file copy command. So I looked for something as simple as issuing
a "Save" command, but that also I could not find.
The second problem is that code snipped does not seem to work in Windows...
