QUESTION
When I run the code the nameGen page evaluation returns a type error that states: "Cannot read property 'innerHTML' of null". The span tag it is targeting has a number value for price and that is what I am trying to get to. How do I access the number value that is contained in the span tag I am targeting? Any help or insight would be greatly appreciated. The element I am targeting looks like this:
...ANSWER
Answered 2021-May-22 at 10:20You have several problems in your code:
you need to wait for the item to be available on the page. looks like the
priceblock_ourprice
is generated after the page is send to the client.In puppeteer, there's a build in function to wait for a certain selector:

ANSWER
Answered 2021-May-14 at 08:12I was actually quite close. The problem is, that python imports modules from another python installation due to a wrong path. Modifying the PYTHONPATH
according to "https://stackoverflow.com/a/4453495/5934316" works for my example.
QUESTION
I'm trying to get the edges of this object from a TEM(microscope) image and the problem is that the contact is low especially in the upper edge, I tried several things thresholding, contrast equalization... but I wasn't able to get the upper edge.
N.B: I'm trying to calculate the angle between the droplet and the tube I'm not sure if this is the best way to approach this problem.
The original image:
The Canny Edge detection I get:
the steps I got to get this result are:
- Contrast enhancement
- Thresholding
- Gauss filter
- Canny Edge detection
Code:
...ANSWER
Answered 2021-Apr-10 at 12:08We have this image and we want to detect the edges of the microphone:
Basically, I converted the image to grayscale, added a Gaussian blur, and detected the edges using the canny edge detector. One more important part is to fill in the gaps in the detected edges by dilating the edges and then eroding them.
All of the above is implemented in the process
function; the draw_contours
function basically utilizes the process
function, and detects the greatest contour:

QUESTION
As the title suggests I am trying to update the axis units when using plt.imshow on .tif images captured from a microscope. Pixel --> microns. lets say 1 pixel is 0.5 microns.
I have made secondary Celsius axes in the past using callbacks, but didn't have luck with imshow. I briefly used imshow parameters origin and extent. It appears those are parameters for orientation. My apologies for providing code as I am writing this remote.

QUESTION
First a clarification that by "alias" I mean finder > right click on file > create alias
, not .bash_profile
stuff (are they the same? I don't know, I confess).
My scenario: I have a huge bunch of microscope scans, images taken at different positions, different focal depths, on different channels etc etc, all in one biiiiig folder.
Files are something along the line of TILE0123_FOCUS0123_CHANNEL0123.tiff
. I would like to sort them in subfolders, but sometimesI need to group them by "same tile, same focus, all channels", sometimes "same focus, same channel, all tiles" and so on. My idea then was to leave the original files unsorted and create all the needed types of grouping with aliases.
The only previous post about python and osx alias paths I found is this one but to be honest it seems way more complicated than I hoped. So I tried selecting all images manually, right-click-create-alias them all, and then use my copying script. Notice that the copying script uses shutil.copy()
My problem: what gets copied is no longer an alias but just a txt file :(
...ANSWER
Answered 2021-Mar-05 at 08:26...if rather than copying, I move (with shutil.move()
), the problem is no more.
I guess knowing a bit more about aliases could have helped.
QUESTION
I want to train some models to work with grayscale images, which e.g. is useful for microscope applications (Source). Therefore I want to train my model on graysale imagenet, using the pytorch grayscale conversion (torchvision.transforms.Grayscale), to convert the RGB imagenet to a grayscale imagenet. Internally pytorch rotates the color space from RGB to YPbPr as follows:
Y' is the grayscale channel then, so that Pb and Pr can be neglected after transformation. Actually pytorch even only calculates
...ANSWER
Answered 2021-Jan-14 at 11:09Okay, I wasn't able to calculate the standard deviation as planned, but did it using the code below. The grayscale imagenet's train dataset mean and standard deviation are (round it as much as you like):
Mean: 0.44531356896770125
Standard Deviation: 0.2692461874154524
QUESTION
First:
I am working on a dark-field microscopic tracking program. This program is old (2012), we got a new camera but this camera can´t be captured with a capture program. So I need to write a "capture program" for this camera with the SDK (Software development kit) from the company of the camera.
The tracking program is writen in C and GTK 2, so I would like to have the "capture program" in C and GTK 2 too, so I can just put the "capture program" in my tracking program. I can take a picture inside the "capture program" and show it as gtk_image_new_from_pixbuf
.
Problem:
After being able to take pictures I found out that the dark-field microscope is not able to let you set the focus for the camera with your eyes. So now I need to capture a "live image", video or how ever you want to call it.
My idea was to use a timer so the camera will take a picture every second and display it as an image so the program has to delete the old image and show the new one.
But that doesn´t happen I am pretty sure that there is no problem with the camera, because it shows the first image. My guess is that the pixbuf isn´t cleared and that causes that there is no new image shown.
The "capture program" doesn´t have to stay as a C/Gtk2 program but as I am not a computer scientist I just have no idea how to get the images into the tracking program if they are different.
Code:
I know that gdk_pixbuf_new_from_data
has a starde of width*1
and not width*3
that is no problem.
ANSWER
Answered 2020-Dec-16 at 14:04The updating of the images is triggered by the expose_event
callback that is draw_call
in your code, for details see How to get webcam feed to GTK window?
You know that there is tracking implemented in OpenCV ? https://docs.opencv.org/3.4/d2/d0a/tutorial_introduction_to_tracker.html
You can also code the image capturing in OpenCV
OpenCV - Getting picture from default webcam in C/C++ - GTK Issues
In GUVCVIEWER is implemented the functionality that you need and possibly you can port the source code if your camera uses the uvc
driver https://github.com/jaswdr/guvcview/blob/master/gview_v4l2core/v4l2_core.c
QUESTION
I have a UIFrame
with a getConfiguration()
function which returns a TagGroup
. But when compiling the script (with the TEM attatched) I get the error No match for =( TagGroup, RealNumber )
telling me that the returned value of the function is a real number. But as shown in the code below, the getConfiguration()
function clearly has the return type of a TagGroup
.
ANSWER
Answered 2020-Dec-07 at 16:47To solve this problem simply rename the function to anything else than getConfiguration()
, e.g. TestDialogGetConfiguration()
, TestDialog_getConfiguration()
, getConfig()
, getConfigurationValues()
1, ...
1Use class prefixes as @BmyGuest suggests in his comment as this prevents collisions with other classes, also explained in the comment below.
I don't know why this bug occurres. There is no UIFrame::getConfiguration()
function mentioned in the help. And even if there were one, the defined function would overwrite the original function or raise any kind of error that the signatures are not compatible.
This is a very confusing behaviour which is unexpected by any programmer and unconsistent with other programming languages and even dm-script. Function names should not matter at all which makes people not even think about this solution here. This is why I think the problem with its solution should be mentioned on stackoverflow. Even though the solution is extremely simple... If you know it.
