kandi X-RAY | devito Summary

devito is a Python library typically used in Hardware, GPU applications. devito has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. However devito has 26 bugs. You can install using 'pip install devito' or download it from GitHub, PyPI.

Devito provides a functional language to implement sophisticated operators that can be made up of multiple stencil computations, boundary conditions, sparse operations (e.g., interpolation), and much more. A typical use case is explicit finite difference methods for approximating partial differential equations. For example, a 2D diffusion operator may be implemented with Devito as follows. An Operator generates low-level code from an ordered collection of Eq (the example above being for a single equation). This code may also be compiled and executed. There is virtually no limit to the complexity of an Operator -- the Devito compiler will automatically analyze the input, detect and apply optimizations (including single- and multi-node parallelism), and eventually generate code with suitable loops and expressions.

This should solve your problem. First it creates a dictionary from your list elements in a try/ except loop so that if there is no height value isntead of throwing an error it puts np.nan instead. Finally it creates the pandas dataframe from dictionary.

I am currently trying to learn machine learning techniques and wanted to recreate a simple image recognition algorithm with tensorflow. Therefore I made two Python-files: One for training and one for prediction.

Hey I believe you are getting strange predictions because your data distribution has 60 classes of people while your model is compiled with a loss function that is set to binary crossentropy.

Binary crossentropy is used to determine a max of 2 classes. What you need to do is change the loss function to categorical crossentropy.

With Knex, you can retrieve data the same as with SQL, which is record based, not object based

However, after a bit of digging I found a package that can achieve something similar to Laravel's eager loading. It is called Objection.js and it allows me to keep my Knex.js migrations

QUESTION

New DF column based on the value of another column. Possible new values obtained by checking the name of pre-existing columns with highest value

Asked 2019-Apr-22 at 04:34

I have a dataframe (will call it 'df') with a decent amount of variables (numeric and characters, there are some NAs in there too). Some of the columns hold the grade of a specific school subject, some other columns are not related at all. Each row represents a dude.

I want to create a new one (will call it 'preferedSubject') with values based on a threshold (let's say 0.5) imposed in another column ('Happiness'); where, if the value of this variable is lower than the threshold, the value of 'preferedSubject' for that row will be a string (let's say... '2Cool4School') and, if higher, the value will become the name of the school subject with the highest score from that row. That is, the name of the column with the highest numeric value (while excluding some of the other columns, remember that some of them are not school subjects)

This of course isn't my data; just decided to use it as a basic and (hopefully clear) example of what's going on, for some reason I always find a way to put it in terms of school subjects and students.

The first part of my problem should be easily handled with the ifelse function I believe; that way I can assign a value to 'preferedSubject' depending on whether 'Happyness' is lower than 0.5 or not. The part that's causing me trouble is the second one, I cannot find a way to retrieve the name of the column (school subject) with the highest score while excluding some other columns (non school subject) first.

Assuming this is my dataframe:

Answered 2019-Apr-22 at 04:34

We could use ifelse and max.col by replacing NAs with 0 and then get index of maximum value in each row.
