QUESTION
I am using a method to remove univariate outliers. This method only works if the vector contains outliers.
How is it possible to generalize this method to work also with vectors without outliers. I tried with ifelse
without success.

which would work even when there are no outliers

QUESTION
I am trying to use thrust with Opencv classes. The final code will be more complicated including using device memory but this simple example does not build successfully.
...ANSWER
Answered 2021-Jun-14 at 14:06As pointed out in the comments, for the code you have shown, you are getting a warning and this warning can be safely ignored.
For usage in CUDA device code:
For a C++ class to be usable in CUDA device code, any relevant member functions that will be used explicitly or implicitly in CUDA device code, must be marked with the __device__
decorator. (There are a few exceptions e.g. for defaulted constructors which don't apply here.)
The OpenCV class you are attempting to use (cv::KeyPoint
), doesn't meet these requirements for use in device code. It won't be usable as-is.
There may be a few options:
Recast your work using
cv::KeyPoint
to use some class that provides similar functionality, that you write yourself, in such a way as to be properly designed and decorated.Perhaps see if OpenCV built with CUDA has an alternate version here (properly designed/decorated) (my guess would be it probably doesn't)
Rewrite OpenCV itself, taking into account all necessary design changes to allow the
cv::KeyPoint
class to be usable in device code.As a variant of suggestion 1, copy the relevant data
.response
to a separate set of classes or just a bare array, and do your selection work based on that. The selection work done there can be used to "filter" the original array.

I am stuck with this error when trying to convert xml file using SSIS with a 'XML task' using xslt:

Disquaire\urls.py
...ANSWER
Answered 2021-Jun-13 at 13:01You have written your urls in the manner /store/ {% url 'details' album_id=album.id %}
for some reason. The url
template tag will give you a relative url from the domain of your site, hence you don't have to prefix your url. Also you write src="{{ album.picture }}"
here I assume picture
is an image field? If so you should be writing src="{{ album.picture.url }}"
instead. Hence change your template to:

I'm trying to produce a cumulative incidence plot for a competing hazards survival analysis using plot() in R. For some reason, the plot that is produced has a legend that I have not called.

QUESTION
I have some lines of code that I use to practice django_rest_framework
and I just pasted them in the python shell from python manage.py shell
.
I have gotten some errors and would like to know what imports I already have.
Is there a function to figure out what was imported? This may be applicable to a python shell as well that isn't obtained from django
.
This may not be necessary but here is the example code that I pasted in the shell while following this tutorial:
...ANSWER
Answered 2021-Jun-10 at 18:08You can check the imports using the built in dir()
function. It actually lists out all the variables, classes, functions, imports etc. declared in the current python shell.
QUESTION
I'm solving the example probation problem in Python and had only partial success so far (passed 30 test cases, wrong answer in the 31st). The test cases themselves are not disclosed.
Description.
A network of n nodes connected by n-1 links is given. Find two nodes so that the distance from the fatherst node to the nearest of those two would be minimal. If several answers are possible, any of them will be accepted.
The input is given as a list of pairs of numbers. Each number represents node, pair is the connection between two nodes. The result should be the list of two nodes.
Example 1 in = [[1, 2], [2, 3]] result = [3, 1]
Example 2 in = [[1, 2], [3, 2], [2, 4], [4, 5], [4, 6]] result = [2, 4]
My solution.
The net will always be a tree, not a graph. For the above examples the corresponding trees will be:
