QUESTION
I'm new to tkinter so please bare with me (Python 3.8.5/Tkinter 8.6 sample code at the end of the post - There is also an Edited Version)
I'm trying to change & keep highlighted the button-bg while the user interacts with the menu, and reset it only after the menu goes away.
This picture shows what I mean (default behavior on the left, mine on the right)
I've researched and tried several things and I've managed to make it partially work. It's not shown in the pic, but additionally the button-bg gets reset when the user closes the menu by selecting an option. However, I cannot detect when the menu gets closed via a click outside the menu.
What I'm doing in the code below, is setting the button's activebackground
upon creation and also forcing it as bg
in the postcommand
option. Then I add an on-click callback to all menu-items (via their command
option) which resets the button's bg. Apparently, the command
callback overwrites their default one, so I'm additionally updating manually the StringVar()
of the OptionMenu
.
I have so many unanswered questions, but the main one is how can I catch the case where the menu gets closed without an option being clicked, so I can reset the button-bg? Everything else works as intended.
And a few more questions if I may:
- Can we obtain the actual widget object of a menu-item? None of the
Menu
widget methods seem to return a menu-item widget (it could save me the overriding of the default callback, and thus updating manually theStringVar()
since I could
menuitem.bind("", callback, add="+")
instead of
menu.entryconfigure(i, command=callback)
Is there a way of passing the event object to the callback when using the
command
option?Do the
""
and""
events even work on om['menu']? They didn't in my tries on Windows (btw same goes for the.unpost()
method)
Thanks in advance for any replies!
Here comes the sample code

Answered 2021-Apr-09 at 23:52how can I catch the case where the menu gets closed without an option being clicked
I don't think it's possible. At least, not on every platform. On OSX and Windows the menu widget is a native widget (eg: not drawn by tkinter), and as such tkinter has very little visibility into what they do once they've been posted.
Can we obtain the actual widget object of a menu-item?
No, because menu items aren't widgets.
Is there a way of passing the event object to the callback when using the command= option?
No. If you want an event object you will need to use custom bindings rather than the command
option.
Do the "" and "" events even work on om['menu']?
Maybe on Linux, but not on OSX or Windows. Again, menus are handled by the underlying OS so tkinter essentially loses control once they are posted.
... They didn't in my tries on Windows (btw same goes for the .unpost() method)
The unpost
method is documented to not work on Windows.
QUESTION
I am teaching myself machine learning and working on some dataset which have the columns
there are two sentences columns sent0 and sent1 and sol contains whether sent0 is against commonsense or sent1. If sent0 is against commonsense there is 0 in sol column.
What I want is to combine both sent0 and sent1 in one column as
Now if a sent0 is against commonsense i want to write it as 0 in sol column and 1 if sentence is right. I tried different ways but failed until now

QUESTION
I'm working on a text classification problem (on a French corpus) and I'm experimenting with different Word Embeddings. I was very interested in what ConceptNet has to offer so I decided to give it a shot.
I wasn't able to find a dedicated tutorial for my particular task, so I took the advice from their blog:
How do I use ConceptNet Numberbatch?
To make it as straightforward as possible:
Work through any tutorial on machine learning for NLP that uses semantic vectors. Get to the part where they tell you to use word2vec. (A particularly enlightened tutorial may tell you to use GloVe 1.2.)
Get the ConceptNet Numberbatch data, and use it instead. Get better results that also generalize to other languages.
Below you may find my approach (note that 'numberbatch.txt' is the file containing the recommended multilingual version: ConceptNet Numberbatch 19.08):
...ANSWER
Answered 2020-Nov-06 at 16:02Are you taking into account ConceptNet Numberbatch's format? As shown in the project's GitHub, it looks like this:
/c/en/absolute_value -0.0847 -0.1316 -0.0800 -0.0708 -0.2514 -0.1687 -...
/c/en/absolute_zero 0.0056 -0.0051 0.0332 -0.1525 -0.0955 -0.0902 0.07...
This format means that fille
will not be found, but /c/fr/fille
will.
QUESTION
Is there a master list of Tensorflow ops that are differentiable (i.e., will auto-differentiate)?
Two other ways to phrase this:
- List of ops that do not have
ops.NoGradient
set. - List of ops that will not trigger
LookupError
.
For example, I'd assume that all the Control Flow ops are not differentiable (e.g., tf.where
). How would I find this other than by manually running them all through tf.gradients
to see if they throw the LookupError
.
"Commonsense" is not a valid answer.
Thanks.
EDIT:
tf.where
is differentiable so my intuitions are wrong. Perhaps the correct question here is which ops in Tensorflow are not differentiable.
Thanks.
...ANSWER
Answered 2017-Jun-15 at 19:01No, there is no list (you can be the first one to create it). Also as far as I am aware, documentation of each function also does not tell it (tf.size
is non-differentiable but does not tell about it).
Apart from the way you suggested, you can also extract this data from the source code. For example all the ops that have gradient implemented, have @ops.RegisterGradient
in front of the method declaration. For ops which do not have gradient you will have ops.NotDifferentiable(
Not related, but probably helpful.

It's meant to get the iid

ANSWER
Answered 2017-Apr-28 at 09:36According to docs x, y
coordinates are
Valid for KeyPress, KeyRelease, ButtonPress, ButtonRelease, Motion, Enter, Leave, Expose, Configure, Gravity, and Reparent events.
