TC	Example of question post
Languages	I am trying to generate predictions for covid cases using a GAM model. The following code works and produces a projection of US cases. I want to apply the same code to any country I choose and therefore thought a simple function would be easiest. This function basically takes all the code above and wraps it up in a function. However — initially it failed at the data subsetting line, so I put the get_df as a helper function. Now it fails at the gam analysis. The error seems to suggest that data$day_num does not equal data$ location length, but I can’t work out why it would say that because they are the same length. I’ve read the various responses on stack overflow and can’t find any answers and hunting around the internet has turned up anything either. I’d greatly appreciate any help! To get the covid data for a fully reproducible example:Tags: r data-science data-modeling gam
Web Frameworks	I am trying to create a simple app with vue-cli and the router that fetches Covid-19 cases by Country from a JSON object of arrays. This is my first Vue app. However, I keep getting an error about “Declaring Reactive Properties”. I searched dozens of similar errors on many different forums and seemed to do the trick. Most of the code is from vue.org, except for the JSON link.Api.js:.About.js...Error:.[Vue warn]: Property or method “errored” is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. I can see the warning 3 times, for each of the props errored, loading and info, the most important one.Tags: vue.js vue-router
Big Data/ML	I am a beginner with TensorFlow and neural networks. I need to run ANN between Protein Sequence and Its Target Molecules. I want to use this trained network for prediction of drug molecule for nCoV-2019. I am struggling with codes here. I get error: Failed to convert a NumPy array to a Tensor (Unsupported object type float).Please help me to write appropriate codes here. Thank you in advance.Tags: tensorflow
Developer Tools	I am building a project about coronavirus tracker for my class. Everytime I tried to call the api and hit the search icon it throws an error in the console. I have tried many things but it throws the same error. can anyone help figure out what is wrong with code? Here is the Api code. Here is the constructorTags: flutter flutter-layout flutter-dependencies
Collaboration Tools	I have created a repo in GitHub named Covid-19-Predictor-BD. I have also linked it up to GitHub Pages which you can see athttps://abd-shoumik.github.io/Covid-19-Predictor-BD/But when I search ’Covid-19-Predictor-BD’ or some related keyword in google , my repo doesn’t appear in the search. What I can do to make the repo appear in google search?Tags: github google-search
Platforms	I’m making a Pi livestreaming covid tracker but watching my CPU/RAM get decimated. When I run that, top gives me %CPU 282%MEM 4.0.I installed ffmpeg with sudo apt-get ffmpeg. I’m not sure if I’m using hardware acceleration. It was brought up in a number of posts that were a year old or so.Tags: ffmpeg raspberry-pi video-streaming
Databases	I’m building an Api that retrieves time series data of covid cases for each country in NodeJS/Express with a mongo DB. The data source is courtesy of John Hopkins. For those lazy to hit the link, the headers look like this: A typical row: I’m trying to model the .csv into a schema that allows for CRUD operations. Having trouble wrapping my head around how each date will dynamically be added on a daily basis. Currently, I have: How best should do I design the mongo schema based on the .csv?
