Recommendation | 商品推荐相关竞赛TOP5解决方案

I am working on book recommendation system, so with ml i have got the recommendation which is stored is list book_list, so using google book api i have tried to fetch the book cover of the listed item in the book_list

I am using asp.net core and programming in C#.

I have a method in a controller to upload a file from a form in a view.

Following AWS Personalize documents, I successfully imported my datasets (User, Item, Interaction) from S3, created an EventTrcker, trained the model, and deployed the campaign. The solution works without any issue and I get the recommendations.

I rely on Putevent to add new user-item interaction events. I also dump those interaction events using Lambda+firehose in my s3. But I am wondering if AWS Personalize internally creates/augments the original user-item interaction dataset? How I can access and download the revised version of the dataset? I cannot see any new dataset in "Dataset groups > Datasets" rather than my original 3 datasets...

I prefer to dump it regularly from AWS Personalize to my S3 storage rather than using my own Lambda+Firehose solution.

This is the output of my Putevent call. I see 200...but not sure it works fine or not...should I see any new dataset in "Dataset groups > Datasets" created by putevents?

My application is returning an error when storing the cache, I saw that it was saving, but it is returning this error. Can anyone say why? Here's my function and the error:

I have a hyper table for exchange candle data set up using TimescaleDB.

• TimescaleDB official image timescale/timescaledb:latest-pg12 set up and running with Docker with the exact version string starting PostgreSQL 12.6 on x86_64-pc-linux-musl, compiled by gcc (Alpine 10.2.1_pre1) 10.2.1 20201203, 64-bit

• Python 3 client

• The table has 5 continuous aggregate views set up like here and around 15 colums

Running the following query is slow (count query generated with SQLAlchemy):

I on working Book recommendation with flask and ml , so i have collected the book's images link in a list, but can't able to figure out how to display those list of images in templates.

this is code where i have the passed the parameter to the templates

I started several attempts to get this complex working. As mentioned in so many other discussions the micropython modules are not recognized, e.g. machine. Python modules like numpy were also not found.

I think, the python environment is not working correctly and the modules are there but not found. But, there is no recommendation or tutorial that really solves this. How can I set this up?

What I did so far:

1. manually installed all components according to tutorials

2. another way: installed the pything coding pack which contains a lot of stuff.

3. The Windows paths have the correct folder paths to the components.

4. I set the obviously correct python interpreter in vscode

5. connection/communication with board is working. I can set up codes which dont contain micropython modules.

6. in other IDE's like thonny/mu the modules are found.

7. I also installed a python venv: I could install numpy inside this venv and later it was found in vscode (wasn't found before) when I used the venv python as interpreter in vscode. But I wasn't succesful with micropython in venv.

PS: I can use the micropython modules like machine or network and upload the sketch to the esp32 board. It is working on the board. But I cant run any of the sketches in vscode. I think that Vscode uses cpython instead of micropython but shouldn't this be working after the installations I mentioned?

I created a MVC ASP.net core project. For pdf reports I am using Rototiva. When working on the local environment everything works fine but when deploying to the azure the report showing boxes.

I have gone through the previous post and tried to fix the issue based on the recommendation but nothing helps, so writing this post if some one have gone through the issue and found the solution.

Note: I am not using free website of Azure.

This is the code and I modified the style based on Jason solution: Controller Partial code:

Update--Issue is resolved

This issue is resolved. My application hosting plan was D1 (shared)on Azure. I had to scale up the app plan and get the B1. Once on B1 I am not seeing anymore issue. But it costing me $40 extra per month to resolve the issue. I would look for some other option to create the report rather than Rotative

This sounds like an easy task, but I already spent hours on it. There're several posts with a similar headline, so let me describe my problem first. I have H264 encoded video files, those files show records of a colonoscopy/gastroscopy.

During the examination, the exterminator can make some kind of screenshot. You can see this in the video because for round about one second the image is not moving, so a couple of frames show the "same". I'd like to know when those screenshots are made.

So in the first place I extracted the image of the video:
