I have 100 csv files each of which when read by pandas dataframe is like below:

I need to convert programatically this to the form as below

so that I can merge all the 100 files to form a large single dataframe

Thanks in advance

I'm trying to filter the list of EC2 instances that I get in my script. I want my search to be based on tags, as we tag instances based on their purpose (service machines, personal gateways, etc).

I use this:

I'm trying to implement a gradient-free optimizer function to train convolutional neural networks with Julia using Flux.jl. The reference paper is this: https://arxiv.org/abs/2005.05955. This paper proposes RSO, a gradient-free optimization algorithm updates single weight at a time on a sampling bases. The pseudocode of this algorithm is depicted in the picture below.

I'm using MNIST dataset.

I receive sporadic the follow error with the Azure CosmosDB emulator on calling CosmosDatabase.createContainerIfNotExists.

• Also if the error message contains many helpless details there is nothing to understand the cause. How can I get more information about the error from the Azure CosmosDB emulator?

• What can be the cause of the error? The count of existing container if the error occur is approximate 70 to 130. This should be no problem for the limit of 250 containers.

• What is the best handling of the error?

I am trying to establish WiFi connection on my Avenger96 (based on 96Boards STM32MP157) board. Goal is to automatically setup WiFi connection during boot time so that there is no need to manually configure WiFi after every boot.

Steps I have done:

1. Added network section in wpa_supplicant.conf-sane as shown below: poky/meta/recipes-connectivity/wpa-supplicant/wpa-supplicant:

How to make Istio route custom HTTP methods?

I am trying to create an API Gateway with Lambda integration but got stuck in an error:

I need to find out the recursive sum of each node of a tree. Please find the image below.

Here the number(assuming no of sales made) in blue is the sum of Parent Quantity + Sum of its children and number in red is sale made by node itself . So if we take example of Node C = 44 , then its calculation is something like this.

Node C has a child F and F has again two children G and H. G & H got no children. But they made 5 and 6 number of sales respectively. Also their Parent F too made 11 sales on his own, so total sales of F will be 22 [ 11 his own and 11 from his children]. Also in the same line C, the parent of F , also got 22 sales of his own. So now total number of sales made by C will be 44 (his own 22 and 22 from his child and grand children).

And this hierarchy and calculation will go on. There's no restriction in depth and breadth of hierarchy as well. A node can have N number of children.

My database has 3 tables as shown in this screenshot:

• StoreMaster: this table contains a master list of all stores.

• StoreMaps: this is a mapping table which maintains the parent child hierarchies. Here MasterStoreId -> ParentId and SlaveStoreId -> ChildId. Both masterstoreid and slavestoreid references to storeid of the StoreMaster table. Also, this maps table supports N level of children in any hierarchy. There's no restrictions at all.

• StoreSales: transaction table for StoreMaster. This table contains store specific sales.

What I want to achieve is that I need a recursive query that will help finding me TotalAmount and Quantity of Sales made by each and every store as shown in figure 1 [above].

I tried using CTE but not getting the desired output. Here's what I tried

I'm new to chart.js and I'm trying to combine a scatter chart with a line chart.

I've been struggling with 2 problems:

1.- I've managed to draw the scatter chart, however the line chart is not displayed. No error message is thrown.

2.- I want to add some labels at the bottom but after many approaches the chart only shows the numbers at the x axis.

I'm attaching an image so you can see where am I right now. I drew the line chart manually.

This is the code I'm using:
