QUESTION
While studying OpenCV, I realized that whenever I blend two images the colors of scr2 have changed in some way(depends on the colors of scr1).
I know this is not an informative and clear way to explain my issue, however; I don't know how to describe this issue since I have no expertise with colors so I would like to show you what I meant with images and code.
The input image: Input image
...ANSWER
Answered 2021-Jun-15 at 16:46I think I misunderstood your issue. If your issue is that the image where you do not have lines has changed, then that is because you used a white background for scr2. The white then mixes with your image in the output. Make it scr2=img.copy() in place of what you have now. Then try your code. So in Python/OpenCV as a demonstration, using the Lena image as background, here is your code:

QUESTION
I am trying to have a number of columns with exact widths, and their heights split evenly between some number of elements. For some reason, despite my indicating an exact 200px width on each column, they are instead getting a computed width of 162px somehow. Chrome dev tools is showing some weird arrow thing indicating that it it was shrunk from it's intended size for some reason. I've even tried removing all of the content from the div's as possible so as to rule out some weird interaction with the size of children.
The html for the relevant area is this:
...ANSWER
Answered 2021-Jun-15 at 20:20Setting display: flex turns the sizing of child elements over to the flex container. If you don't want the individual elements to resize, set flex-grow: 0, flex-shrink: 0, and flex-basis: 200px. You can do all three using the flex shorthand:

I am currently trying to build OpenPose. First, I will try to describe the environment and then the error emerging from it. Caffe, being built from source, resides in its entirety in [/Users...]/openpose/3rdparty instead of the usual location (I redact some parts of the filepaths in this post for privacy). All of its include files can be found in [/Users...]/openpose/3rdparty/caffe/include/caffe. After entering this command:

Answered 2021-Jun-15 at 18:43You are using cmake. The makefiles generated by cmake don't conform to "standard" makefile conventions; in particular they don't use the CXXFLAGS variable.
When you're using cmake, you're not expected to modify the compiler options by changing the invocation of make. Instead, you're expected to modify the compiler options by either editing the CMakeLists.txt file, or else by providing an overridden value to the cmake command line that is used to generate your makefiles.
QUESTION
A part of my form contains QGroupBox (Status Box) with 4 child QGroupBoxes arranged in a grid layout (2x2). Two bottom QGroupBoxes (Widget 1 Box and Widget 2 Box) contain widgets of fixed size (with set minimumSize and maximumSize) so they're non-resizable at all in both directions. Because of that rigid size constraints top row of QGroupBoxes (Summary Box and Helper Box) can only be resized in vertical direction.
And here comes the troublesome part. Top-left QGroupBox (Summary Box) have grid layout 5x3 while top-right (Helper Box) have vertical layout with 6 rows. If I have naive widget placement as shown on picture 1 Qt is enlarging vertical size of both labels in top row to make height of both QGroupBoxes equal (see red arrows on picture 1).
This is definitely that I don't want so I've added vertical spacer to the bottom of Summary Box and from the first glance it worked (picture 2). But only from the first glance... What you see is the minimum height of my whole form and the bottom side of spacer and last QCheckBox in the Helper Box seems to be aligned.
If I'm expanding my form vertically this spacer grows a bit and that causes the increase of height of both top QGroupBoxes. As a result spacing between QCheckBoxes increases too and we can also see that top and bottom spacing are unequal for the top-right box (see red arrows on picture 3).
I've tried to play with sizeType for my vertical spacer. If I set it to Minimum or MinimumExpanding then the spacer doesn't grow on resize (and doesn't shrink, too) but it appears to be expanded to the size as on picture 3 (corrupting spacings between QCheckBoxes too). If I set it to Maximum, Preferred or Expanding then I observe the same behavior as described above for picture 3.
What is the proper way to achieve alignment for two QGroupBoxes in a row of grid without affecting spacing between elements (e. g. in that case make vertical spacer to fit only single row of grid layout and never expand/shrink)?
ANSWER
Answered 2021-Jun-15 at 17:18Items will be aligned if both QGroupBoxes have same count of children and each row have at least one child with Expanding vertical policy. Instead of spacer use QWidget
I removed unrelated widgets and reduces number of rows to 4 for demonstration purposes (less xml).

QUESTION
I have created a simple Rspec test to verfiy if a model created has been deleted. However, the test fails because the model still exists. Can anyone provide any assistance on how to determine if the record was actually deleted?
...ANSWER
Answered 2021-Feb-08 at 20:41When you delete a record from a database, an object still persists in memory. That's why expect(person).to be_empty() fails.
RSpec has the change matcher. ActiveRecord has the persisted? method. It returns false if a record is not persisted in a database.

Answered 2021-Jun-15 at 13:53There are all manner of clustering algorithms and many are implemented in scikit-learn.cluster. They are well documented and the docs have nice examples, but the various algorithms have trade-offs which can take a while to figure out. For example if you have a general idea about how spaced the clusters are (reflected in the epsilon parameter) you can get good results with DBSCAN:
QUESTION
I'm trying to sort my rows according to the Status (B), according to a custom order. I used to have Status in A, and the code worked fine, but then wanted to add an additional column before it and everything's been scuppered. Now getting a 1004 error.
My table spans A:L. Here's the code:
...ANSWER
Answered 2021-Jun-11 at 21:02The error implies that it can't find a range to work with.
As we are working with a table, the .Columns(2) wont work.
This part hints that you have a table that your are trying to sort.
There's two approaches that I can think of now, to solve this:
1. Sort a regular range by custom list
We can remove the table by:
- Click on the table
- Go to design tab
- Convert to Range
Then your originally code will work (Changed Key1:=.Columns(2)):
