You have included fetching function in the component as it is, so it fires every time component being rendered. You better to include fetching data in useEffect hook just like this:

So, this is a good opportunity to use purrr::map. You are half way there by applying code to one dataframe.

You can take the code that you have written above and put it into a function.

ANSWER

Answered 2021-Jun-15 at 19:08

A CSV file is a list of strings separated by commas, with newlines (\n) separating the rows.

Due to this simplistic layout, it is often not suitable for containing strings that may contain commas within them, for instance dialogue.

That being said, with your input file, it is possible to use regex to replace any single newlines with a comma, which effectively does the "each new line converted into a column, each new paragraph a new row" requirement.

Find proportion of times each character(A,B,C,D) occurs in each column of a list which has 3 datasets

I have a list (dput() below) that has 4 datasets.I also have a variable called 'u' with 4 characters. I have made a video here which explains what I want and a spreadsheet is here.

The spreadsheet is not exactly how my data looks like but i am using it just as an example. My original list has 4 datasets but the spreadsheet has 3 datasets.

Essentially i have some characters(A,B,C,D) and i want to find the proportions of times each character occurs in each column of 3 groups of datasets.(Check video, its hard to explain by typing it out)

Answered 2021-Jun-09 at 19:00

We can loop over the list 'l' with lapply, then get the table for each of the columns by looping over the columns with sapply after converting the column to factor with levels specified as 'u', get the proportions, transpose, convert to data.frame (as.data.frame), split by row (asplit - MARGIN = 1), then use transpose from purrr to change the structure so that each column from all the list elements will be blocked as a single unit, bind them with bind_rows

Deeplabv3 re-train result is skewed for non-square images

Asked 2021-Jun-15 at 09:13

I have issues fine-tuning the pretrained model deeplabv3_mnv2_pascal_train_aug in Google Colab.

When I do the visualization with vis.py, the results appear to be displaced to the left/upper side of the image if it has a bigger height/width, namely, the image is not square.

The dataset used for the fine-tune is Look Into Person. The steps done to do so are:

Create dataset in deeplab/datasets/data_generator.py

ANSWER

Answered 2021-Jun-15 at 09:13

After some time, I did find a solution for this problem. An important thing to know is that, by default, train_crop_size and vis_crop_size are 513x513.

The issue was due to vis_crop_size being smaller than the input images, so vis_crop_size is needed to be greater than the max dimension of the biggest image.

In case you want to use export_model.py, you must use the same logic than vis.py, so your masks are not cropped to 513 by default.

ANSWER

Answered 2021-Jun-15 at 05:47

Chris W. is 100% correct, using a vector editor like Adobe Illustrator, Inkscape, or Affinity Designer will make your life much easier when working with complex shapes in SVG. However, for simple shapes like this it doesn't hurt to understand the inner-workings of SVG curves. Not only will it help you malke mathematically perfect shapes but your code will also (usually) be much smaller than what an editor will produce.

The example I'm showing here is only one possible approach out of many to accomplishing this shape. I'll explain the procedure and series of commands briefly but I've also included a second copy of your shape with comments and additional shapes to highlight what the control points are doing (this helps me visualize SVG code).

First it moves to a point at x0, y 100 and draws a relative cubic curve (c) whose first control point is right 100px from the start point with no vertical change and whose second control point is right 180px and up 90px from the start point. The following s curve assumes that it will reflect the previous control point of the c curve before it so it only needs it's second control point and end point specified both of which are designated relative to the end point of the c curve and mirror the previous control points of the c curve. The rest is an absolute vertical line (V) to the bottom of the SVG, an absolute horizontal line to the bottom left corner (H) and a Z to close the path. SVG is awesome, hope this helps you.

In R Shiny, why do my functions not work when using the render UI function but work fine when not using render UI?

Asked 2021-Jun-14 at 22:51

When running the first "almost MWE" code immediately below, which uses conditional panels and a "renderUI" function in the server section, it only runs correctly when I comment out the 3rd line from the bottom, observeEvent(vector.final(periods(),yield_input()),{yield_vector.R <<- unique(vector.final(periods(),yield_input()))}). If I run the code with this line activated, it crashes and I get the error message Error in [: subscript out of bounds which per my research means it is trying to access an array out of its boundary.
