I have an array like this

I'm trying to apply text categorization using Keras. I have imported my data as a Pandas dataframe and have converted it to a tf.Dataset. The problem is that I cannot use the TextVectorization layer of Keras as the below code throws this error:

AttributeError: 'NoneType' object has no attribute 'ndims'

My CSV's headers:

• Class Index : int32
• Title: string
• Description: string

What have I missed ? Below is my code:

I have a simple_form form setup and it will show inline errors fine. I have had problems with some users not seeing these errors and have had requests for a clear enumeration at the top of the very long form. I've used the code setup from the Rails Tutorial:

We have installed R 4.1 on one server and it produces gibberish when running external script through SSMS (SQL Server Management Studio). We used this guide when installing: Install an R custom runtime for SQL Server

I am using display: flex for a container (.zone-container) to position the children. However, I am applying position: absolute to one of the children (#camp-zone) in order to place it on top of the other children. I want to remove the position: absolute from the child element in the media query and apply the same style for all the children (except for background-color). I have tried to set position to static in the media query for both the element that has position: absolute and the container that has position: relative but the child element continues to have different style compared to the other children. How do I unset the specific styling in the media query?

I want to split strings into columns.

My columns should be:

What I am trying to achieve is this: I want to change the color of the buttons when you click on them depending on the type of activity. For instance if you click on a button that has activity "concentration" the specific style class for the activity type should be applied when you click on the button. What I am struggling with is to access the activity.type in my changeStyle function. How do I access the activity type and get the button to change color based on the activity type?

I'm getting this error MongoExpiredSessionError: Cannot use a session that has ended.

I've tried the answers proposed in similar questions and they mainly suggest to use the await keyword. But as you will see in my code below, I already have set that keyword for all my database functions.

I'm using a proxy to connect the server and the client(React). Sometimes it works fine, but then when I update some code in my client, for some reason the server will throw this error. Then, when I edit something in my server file, it starts working fine again (until I edit something in the client). I'm guessing that the problem lies in the fact that I'm using a proxy.

I followed this tutorial on how to setup a react app with a node js server. Let me know if there is a better alternative.

Here is my code:

I got the following error after upgrading R to the latest version

R graphics engine version 14 is not supported by this version of RStudio. The Plots tab will be disabled until a newer version of RStudio is installed.

So, I upgraded to the lastest RStudio v1.4.1717 from v1.3.959 following the official instructions here

This did not work, I still do not have use of my Plots tab. When I run plot(c(1,2,3,4,5,6,7)), it just prints an empty 4kb pdf file to the current working directory instead of the expected:
