QUESTION
Need assistance with the simple task. I’m playing around with the LISC dataset that contains hematological images taken from peripheral blood and segmentation masks of manual ground truth for these graphical samples. The task is the following:
- Segment isolated leukocytes by removing/cropping irrelevant background elements using the segmentation masks given in the dataset. Try this on one sample only.
- Once accomplished, go through the whole folder, and segment/crop the rest of the samples.
Results should be like this (these were obtained via a combination of Mask R-CNN, GrabCut, and OpenCV — but not suitable for the current project I’m working on):
Here is the code that I’ve got so far (from jupyter notebook):
...ANSWER
Answered 2021-Apr-27 at 15:29The change in colors is the result of the specified heatmap (viridis instead of binary) as noted above in comments.
The output image has different coloration than the input image because OpenCV uses BGR rather than RGB for colors, so it's likely your red and blue channels are swapped. If you read an image with OpenCV and plot with Matplotlib or vice versa. There are two easy solutions:
1.) Both read and plot images with OpenCV. You can replace plt.imshow(im_orig)
with:

I am currently using SDK version 3.39.0
and version 0004
of the API_MKT_CONTACT
service definition to try to create a new Contact with an AdditionalID in Marketing Cloud with the following code:
ANSWER
Answered 2021-Mar-16 at 13:58It's not you doing something wrong, it's also not the SDK, it's the service. The service seems to substantially deviate from the OData V2 conventions as well as basic HTTP conventions.
You can work around this by leveraging the low-level APIs of the SDK even more. Create the update request fully manually with the payload the service requires, e.g.:

I am currently using SDK version 3.39.0
and version 0004
of the API_MKT_CONTACT
service definition to create a new Contact in Marketing Cloud with the following code:
ANSWER
Answered 2021-Mar-12 at 07:37To update an entity you should get it from the service first. That is regardless whether you are using:
PATCH
which will update only changed fields- or
PUT
which will send the full entity object
Currently you are creating a new entity object via the builder: ContactOriginData.builder()
. Instead, please use the corresponding getContactOriginDataByKey()
method of your service to first retrieve the entity to update from the service. Actually many services will force you to do this to ensure you are always editing the latest version of your data. This often happens via ETags which the SDK will also handle for you automatically.
You can find more information about the update strategies from the SDK on the documentaiton.
Edit: As you pointed out in the comments the actual goal is to create an entity and the specific service in question only allows PUT and PATCH to create objects.
In that case using replacingEntity()
(which translates to PUT
) should already work with your code. You can make PATCH work as well by replacing the builder approach with a constructor call + setter approach.

I am trying to display multiple images for displaying in my booking system but the images are simply appearing in one column like this
While this is how I expected them to appear So far I am using bootstrap to style the images. What I want is to loop through the returned images and show the first three in the first row then the second four in the following row showing the number of all that are hidden in the last column of the last row just as in the image
So far this is what I have been able to do

QUESTION
Basically I use tf-gpu 2.3rc0
to perform image detection on a video stream. For each loop, there's a subtask runs separately. So I try to use Pool
from multiprocessing
The structure is like:
ANSWER
Answered 2021-Feb-15 at 21:09it seems likely you're not only re-initializing tf
for each frame, but you're starting a new process for each frame, then killing it after it's done. One of the benefits of a Pool
is letting some initialization happen in the child process, then keeping it around to execute multiple tasks. I think a simple solution would probably be re-arranging your code to look something like this, though it's hard to know with what you've posted.
QUESTION
I have downloaded a bunch of graphs from http://users.cecs.anu.edu.au/~bdm/data/graphs.html and I want to do some analysis. I want to use the graph-tool
Python module for this but I cant find a convenient way to convert from graph6
format to a format compatible with graph-tools
. There must be an easy way to do this... any help would be appreciated.
-- EDIT: A possible solution is convert from g6 to gt format... but I haven't found any tools that do this.
...ANSWER
Answered 2020-Dec-09 at 01:50The graph6
format looks annoying to work with, but fortunately the documentation mentions a tool named showg
for pretty-printing graphs. It's easy to simply parse the output of that program.
First, build the showg
tool. (Use clang
or gcc
as appropriate for your system. Or just download the binary they provide on their website.)

I have an extremely large, unsorted pandas dataframe (over two million rows) with multiple columns, two columns of which identify which category these rows belong to. Where the combination of "K" and "U" represent a unique category for these rows, I want to select all the rows that fall into each of these categories, and store these rows as separate dataframes that can be manipulated and analyzed later on for machine learning models.

I have to make a Tictactoe for a project, and while i do know that the code is not good, i can´t see what the error is, the value is assigned to the dict, if i print the key for the last play its correctly show me if is an X or a O, but the value is not represented in the last print of the board.
...ANSWER
Answered 2020-Oct-22 at 14:43You are assigning the new X
or O
to tablero['algo']
. If the game doesn't end here, you assign the contents of tablero
to ari
, arc
, etc., but only at the start of the next loop.
So if the game does end after that move, you print the old ari
, arc
, etc. which have not yet been updated to reflect the latest move.
Of course, there are many other things you should fix (lots of repetition that can be avoided), but the game does work correctly.
Some suggestions:
I would use a simple list to handle the board. tablero = [" "] * 9
creates a list of nine space characters. This allows for a lot of simplications down the line. For example, to print the board, you can simply do
