kandi X-RAY | Dryad Summary
This is a research prototype of the Dryad and DryadLINQ data-parallel processing frameworks running on Hadoop YARN. Dryad utilizes cluster services provided as part of Hadoop YARN to reliably execute distributed computations on a cluster of computers. DryadLINQ provides the LINQ programming model for distributed data processing and leverages Dryad for reliable execution. If you just want to run a sample DryadLINQ program, the simplest way to get started is to follow the instructions at Visual Studio 2013 An Azure HDInsight 3.1 cluster or a Windows YARN cluster composed of x64 machines.

QUESTION
I am trying to carrying out calculations on individual values that are stored in a nested list stored in a pandas DataFrame. My issue is on how to access these individual values.
I am working from a data set available here: https://datadryad.org/stash/dataset/doi:10.5061/dryad.h505v
I have imported the .json file in a pandas DataFrame and the elastic constants are stored in the column 'elastic_tensor'.
...ANSWER
Answered 2021-Mar-10 at 16:46- approach using
apply(pd.Series)
to expand a list into columns - using
stack()
andunstack()
generate multi-index columns that are zero-indexed values into 2D list - flatten multi-index to match your stated requirement (one-indexed instead of zero indexed)
QUESTION
I have a .sql file containing code to create a database. This file has been created using Sequel Pro SQL dump Version 4096, a software running on Mac. However, I am on Windows and I just can't find out how to run this file successfully.
I have tried with SQLite 3 and DBeaver 7.1.0 without success.This post suggest to use the same software: "So to be certain, you need to run the script in the same database engine software that was used to create it" but as you can imagine this is not possible here.
Do you know a software that could open it and allow me to save this .sql file in another format (at least something BDeaver can read...)
The dataset is open source, available here: https://datadryad.org/stash/dataset/doi:10.5061/dryad.mf42f To make this example fully reproducible, what should I include?
This is my 1st time dealing with .sql files and databases' world. Please let me know if I informations are lacking or if I am doing things wrong.
...ANSWER
Answered 2020-Jun-17 at 09:51A .sql file is just plain text file with a different extension. So normally, you can open it with Notepad or any text editor such as Geany, Atom or Notepad++.
If you wish to execute the SQL script, in DBeaver, you first have to create the connection to the target database. Then, in the database navigator on the left, right-click on your database and select "SQL editor". A new empty SQL editor opens, linked to your database. Then click on "SQL Editor" in the top bar, and click on "import SQL script":
Navigate to the .sql file and select it.
Just in case, DBeaver also exists on Mac so if you need to use several OS it might be convenient to install DBeaver on all your computers and so keep the same tool everywhere.
Steps to follow to create a database from a .sql file
If you have an SQL script to create mySQL database, it will not run fine in a SQLite or any other database. For example, mySQL CREATE TABLE would mention something like ENGINE=InnoDB. SQLite will not understand this option. And it is generally true : SQL script are very similar from one database system to another, but not exactly identical. So unfortunately not interchangeable.
So to transfer your database from one computer (let's say the "source") to another (let's say the "target"), you need first to "dump" it i.e. to put all SQL instructions to create it into one file. As I understand you have already done it.
Then you will have to reinstall the same database engine (so mySQL in your case I guess) on the target computer. Then connect DBeaver (or whatever client : mySQL Workbench, Datagrip, even command line...) to this database and execute the script as shown above.
The SQL script is NOT the database, it is just the steps to create it. The database engine will read your SQL script and recreate your database accordingly.
QUESTION
I'm trying to populate a multi-dimensional array with two vectors of the same length. The input data should alternate between the vectors, so that the first input is the first object of the first vector, the second input is the first object of the second vector and so on. I searched for similar problems on this site and found the function rbind(), however, this will not work as soon as my third dimension is unequal to 1.
In short, I want to achieve this:

QUESTION
I am trying to plot a logistic regression in R. I currently have this code...
...ANSWER
Answered 2017-Nov-02 at 17:24The main issue is that the logistic curve you're plotting is approximately linear over the range of data you've got (this is generally true when the predicted probabilities are in the range from 0.3 to 0.7).
You can get standard errors on the plot by specifying se=TRUE
in the geom_smooth()
call ...
In the plot below I (1) used stat_sum()
instead of geom_point()
to visualize the overlapping points in the data set; (2) used fullrange=TRUE
to get predictions over the full range of the plot (rather than just the range actually spanned by the data); (3) used expand_limits()
to push the graph out to large age values, to illustrate that the prediction does look nonlinear if you extend it to low or high enough predicted probabilities (to get to high probabilities, you'd need to make age negative ...)
