'Parameter name clashes for keys' in Detail View #118

chbrandt · 2020-02-24T22:26:53Z

The Query Filter mechanism -- available under the Flags Filter -- allows the user to subsample datapoints through a "free" query expression over metrics columns.

When I test the Query filter with the Skyplot View active, things seem to work fine; I can "Run the query", then "clear" it, and notice some reaction on the Skyplot. If I then change the view to Detail View a log message (is written to the terminal):

Parameter name clashes for keys {'height', 'width', 'scale'}

Below I will put a series of screenshot of this procedure to make it as clear as possible. But before, I would like to add that if the Query Filter is run while the Detail View is active, the dashboard crashes with the same message (Parameter name clashes for keys {'height', 'width', 'scale'}) at the end. I will put the respective error stack at the end, after the screenshots.

Example of workflow to reproduce the "unexpected message in the terminal":

(Load data and) chose a metric (psfTraceSdssDiff_percent for instance) to visualize
Run Query Filter
Clear it
Change to Skyplot View (all seems ok, notice that datapoints are not subsampled anymore -- we cleared the query/filter)
Message in the terminal

Error stack

If we do the steps above looking at Detail View active instead of Skyplot View we will see the following (crash):

@philippjfr I saw something similar here holoviz/holoviews#3831. Any ideas of how I could work around this (or whether I'm doing something wrong)?

The text was updated successfully, but these errors were encountered:

philippjfr · 2020-02-24T22:33:07Z

Seems like a bug in HoloViews, seems like that utility needs to be updated to inspect the function wrapped by the partial.

philippjfr · 2020-02-24T22:33:32Z

PR would be welcome as I'm pushing hard on getting various features done.

chbrandt · 2020-02-27T22:00:42Z

OK, thanks. I will look into it. If you have any directions to arrive quicker to tackle the problem, feel free to be the boss.

philippjfr · 2020-02-27T22:14:25Z

Just FYI, I've already handled the "Parameter name clashes" issue separately in holoviz/holoviews#4119.

chbrandt · 2020-02-28T10:30:46Z

Nice, thanks. I'll clone it and check on my side.

chbrandt · 2020-02-28T15:25:13Z

Yes, I checked out Hv seleciton_mode branch and installed. Something is still there: same workflow, crash, but different error:

Will look if I can spot it.

chbrandt · 2020-02-28T16:00:25Z

@philippjfr I applied a very naive patch to that, it is here: https://github.com/chbrandt/holoviews/commit/739802c991684ce93978774436e3312f505a7de3 . I could not follow where __self__ is assigned so I decided trust on your coding and return a None (which is certainly no in the stream). But maybe you have a word on that?
PS: it does (afai can see) solve my crash.

timothydmorton · 2020-02-28T17:23:43Z

I've seen that same error elsewhere, too, though don't remember the exact context.

philippjfr · 2020-03-04T13:36:35Z

Fixed in holoviz/holoviews#4259

chbrandt · 2020-03-06T15:23:31Z

This is strange @philippjfr ... still,

/Users/chbrandt/Estudos/Codigos/repositories/PARIETAL/holoviews/holoviews/core/util.py", line 549, in get_method_owner
    return method.__self__ if sys.version_info.major >= 3 else method.im_self
AttributeError: 'function' object has no attribute '__self__'

is comming out.

I'm at the latest:

    Require firefox and geckodriver for doc builds (#4272)

My env has it installed:

philippjfr · 2020-03-06T21:39:43Z

That's odd indeed. I'll look into it.

philippjfr · 2020-03-10T12:24:58Z

Should be fixed in holoviz/holoviews#4275

chbrandt · 2020-03-11T17:17:28Z

Yep! Awesome.
