QUESTION
So I have trained a tensorflow model for OCR using a alphabet dataset i downloaded from here
creating Xtrain, Xtest and Ytrain, Ytest: folders contain folders of each alphabets with 15k images in it of sixe 32x32.
...ANSWER
Answered 2021-Jun-01 at 06:48Since you have trained the model using 32x32 image, you need to give an input image of the same dimension to your model.
Step 1: Load the input image from the disk, convert it to grayscale, and blur it to reduce noise
Step 2: Perform edge detection, find contours in the edge map, and sort the resulting contours from left-to-right
Step 3: Loop over the contours, compute the bounding box of the contour and filter out too small and large boxes.
Step 4: Extract the character and threshold it to make the character appear as white (foreground) on a black background, then grab the width and height of the thresholded image
Step 5: Resize the image and apply padding if needed
Step 6: Run your model for all the chars found

The issue seemed to be related to some dependencies, in particular: xunit
and Microsoft.NET.Test.Sdk

the solution was by adding true

I am a novice programmer and new to adobe extensions but have developed an extension that is not working correctly in Photoshop 2015. It works perfectly in PS 2017, 2018 and 2019.
I am reading array data from a JSON file with JSX and using an event listener in the main.js file to return the data. The extension reads the settings from the returned array. It works perfectly except in PS 2015 where it can only return the UserID but nothing else.

Answered 2019-Oct-18 at 20:54Maybe there's a great story behind this, but apparently event object parser in CC2015 is broken: while simple object work (so your datareceived_arry['userinfo']['userid']
is accessible) arrays are converted to strings: JSON that the panel receives looks like this (notice all the arrays are strings now):

in AppleScript is "Can't get «script»"
, indicating that the first item of args
is a script object reference. This means that the command-line argument is not getting passed to your AppleScript's run

Instead of saving your AppleScript as an applet, save it (export it) as either a .scpt

QUESTION
Does the SharePoint list (office 365) have a capability to act as a slowly changing dimension like in SSIS? To avoid question like? Why not use SSIS? or Why use a SharePoint list to make it work like a slowly changing dimension?
Facts: 1. We don't have SSIS in my company, we only have office 365. 2. So my colleagues gather data manually and put it in a database, they call the excel sheet as database. They wanted me to create a SharePoint list and upload the first batch of the data and then update the list as the excel spreadsheet gets updated.
For example, the first data I copied and pasted from excel and then put it in a Sharepoint list. I have an excel sheet with a table
...ANSWER
Answered 2018-Sep-07 at 04:07I'm not familiar with SSIS, so I only answer the question stand in the perspective of Excel and SharePoint.
- Create a document library and upload your excel to the library. Change or update the content online.
Create an workflow for the document library, while the excel file is changed, the workflow will start. Then this workflow will update the content to the SharePoint List you have created.
If you can use the Visual Studio Workflow, you can filter the changed data and update the corresponding records in SharePoint list. If you don't have VS/C# basic, you can use the SharePoint Designer to design the workflow, but iterate over the excel with 5,000 rows may encounter unpredictable problems(But this is the simple way for none-developer).
Official workflow resources for you.

I am relatively new to R; and, I need help with a user defined function. I would like to see where each observation of a data frame ranks in a subset of similar observations of the same data frame. I'm having trouble referencing the original observation, in order to extract its rank, within my function.
Here is a sample of my data:

Answered 2018-Feb-08 at 07:13You're using data.table
for little steps in your process, but you should just use it for the whole thing. It's very convenient for doing operations "by group", in this case using rank()
by Game.ID
