--iversion does not work on dask

[rasbt]

No worries, thanks for the update, and I am glad that it works now! (btw. I added a new issue to fix the ugly alignment of the version numbers)

[rasbt]

Thanks for the note! Yes, this can (and should) be modified, indeed, to support packages that don't use the standard version attribute. For instance, the -p flag also considers .version and .version_info, which I encountered in a few packages. The same could be done for --iversion and -p should also be modified to support ._version

I am a bit busy this week but I am happy to put that onto my todo list. In the meantime, I'd happy to accept any PRs if someone likes to fix it before I get a chance :)

-p dask does work
It's just more convenient to type

%load_ext watermark
watermark -d -iv 

at the top of each notebook

[rasbt]

Oh, actually it does work with dask in my case ;). After I saw your second comment, I was thinking that you may have run --iversions before you imported dask? The --iversions flag currently only considers those packages that were imported during the session.

So, in order to use it properly, one needs to run it either at the end of a notebook or rerun it after the other cells in the notebook got executed.

[tobsecret]

No, that is not the case in my notebook.
The first cell is imports, the second cell loads and calls the watermark extension.
I have dask 0.15.0 though but it seems like they also have ._version in dask 0.15.1.
And the following works:

%watermark -iv -v -w -p dask

and prints out:

seaborn     0.8.0
pandas      0.20.1
numpy       1.11.1
CPython 3.5.2
IPython 5.1.0

dask 0.15.0
watermark 1.5.0

If I leave out the -p flag:

%watermark -iv -v -w 

the following is printed however

seaborn     0.8.0
pandas      0.20.1
numpy       1.11.1
CPython 3.5.2
IPython 5.1.0
watermark 1.5.0

Sorry for wasting your time, found the issue.
I was importing from dask

from dask.distributed import Client, progress

but not importing all of dask itself.
