Can I use group_map or group_walk to iteratively export results?

Asked 2021-Jun-06 at 01:50

I want to iteratively process a master list of comparisons using group_walk() or group_map() as an alternative method to import batches of .csv files.

I would like to input a dataset that looks like this:

Test Assay Var1 Var2 Freq Assay1 neg neg 19 Assay1 neg pos 5 Assay1 pos neg 8 Assay1 pos pos 141 Assay2 neg neg 25 Assay2 neg pos 6 Assay2 pos neg 17 Assay2 pos pos 33 Assay3 neg neg 99 Assay3 neg pos 20 Assay3 pos neg 5 Assay3 pos pos 105

I want to use the function epi_analysis and export a csv for each Test Assay (in this example Assay1, Assay2, and Assay3). So far I have:

You need to call your function in group_map. Also the function requires two arguments so pass the_dir_ex as well.

Get the Text Value of a Anchor Tag inside a JQuery Datatable Cell

I have Table element and one of the cells carries an Anchor Tag.

I want to get the Text of the Anchor tag of each cell.

i.e. If a Cell has a value as Hello then I want to get the value as Hello

I used to have a dummy DOM by referring to this post:

You are already getting a tag i.e : var rVal = data[i][0]; so to get text you can simply use $(rVal).text() or to get text from $('

').html(rVal).contents() you can use el.text().

QUESTION

Interactive annotations only show up for one data set in matplotlib

Asked 2021-Apr-23 at 18:25

I wrote a script with annotations that get displayed upon hovering over data points based on some of the answers to similar questions by the user ImportanceOfBeingErnest. One of the changes I've made is that I only change the text and position of a single annotation and use it for more than one data set. This seems to cause the problem that the annotation only gets displayed for the last data set (or plotter, as I called them in my script) in the list of all data sets/ plotters.

How can I get the annotation to display for all data points of both scatter plots in my script? Do I have to make a new annotation for each data set and update them separately?

...

ANSWER

Answered 2021-Apr-23 at 18:25

The main problem is that the hover event gets triggered by the line instead of by the nearby scatter dots. So, this line should be excluded when connecting the motion_notify_event.

Since ImportanceOfBeingErnest's and others posts about how to create annotations, they developed the mplcursors library to strongly simplify the creation of this kind of annotations.

With mplcursors you can simply call mplcursors.cursor(ax.collections, hover=True) and automatically an annotation with x and y positions would be created. But easily can go much further. The example below also shows how to display the artist's label (here the 'artist' is one collection of scatter dots). Also, how to use the artist's color for the background of the annotation. Further, an extra attribute is added to the artist with a list of names. These names are then added to the annotation.

The code leaves out some of the elements that aren't relevant for the annotations, such as the large text.

FLIR Lepton Thermal Camera & Python OpenCV

Asked 2021-Apr-14 at 21:48

I'm trying to stream FLIR Lepton 3.5 with Python OPENCV using "VideoCapture" & "cv2.imshow" script. Then, I'll do some detection and control. Here's the problem I have, I was only able to get a very faint black/gray video stream with what seems to be a couple of rows of dead pixels at the bottom of the stream. This is expected since the output is supposed to be 16-Bit RAW image data. So,

I'm trying to convert to RGB888 image data so the stream has "colors".
Why is the stream video in static mode, it doesn't stream video like normal embedded notebook webcam?

I've tried the codes/scripts that were shared by others and even the example code from FLIR application notes, but didn't work. Your help is appreciated.

It's challenging to give an answer without having the camera.
Please note that I could not verify my solution.

I found the following issues with your code:

rval, frame = video.read() must be inside the while loop.
The code grabs the next frame.
If you want to grab more than one frame, you should execute it in a loop.
normed = cv2.normalize(frame, None, 0, 65535, cv2.NORM_MINMAX)
Returns uint16 values in range [0, 65535].
You are getting an overflow when converting to uint8 by np.uint8(normed).
I recommend normalizing to range [0, 255].
You may also select the type of the result to be uint8:

Sagemaker Endpoint BrokenPipeError at DeepAR Prediction

ANSWER

Answered 2021-Mar-19 at 14:47

I believe that Tarun might on the right path. The BrokenPipeError that you got is thrown when the connection is abruptly closed. See the python docs for BrokenPipeError. The SageMaker endpoint probably drops the connection as soon as you go over the limit of 5MB. I suggest you try a smaller dataset. Also the data you send might get enlarged because of how sagemaker.tensorflow.model.TensorFlowPredictor encodes the data according to this comment on a similar issue.

If that doesn't work I've also seen a couple of people having problems with their networks in general. Specifically firewall/antivirus (for example this comment) or network timeout.

Hope this points you in the right direction.
