Haskell monadic parser with anamorphisms

Asked 2021-Jun-11 at 01:28

My problem is how to combine the recursive, F-algebra-style recursive type definitions, with monadic/applicative-style parsers, in way that would scale to a realistic programming language.

I have just started with the Expr definition below:

The problem is resolved when blit=False, though it may slow down your animation.

Just quoting from a previous answer:

"Possible solutions are:

Put the title inside the axes.

Don't use blitting"

See: How to update plot title with matplotlib using animation?

QUESTION

What are the guidelines for using numba for a tree structure?

Asked 2021-May-31 at 16:09

Edit: Forgot to run numba more than once (oops!)

Ive looked at the numba versions of namedtuple and Dict as potential solutions but they seem much slower (about 10000x slower) in comparison to their python counterparts.

...

ANSWER

Answered 2021-May-31 at 03:48

The biggest issue is the fact that you are measuring the first execution of build_params_numba, which includes the compilation (it is compiled Just-In-Time, just as you requested). This is like measuring the time-to-dinner between a classic meal and a microwave meal, but you're including the time to buy and install a microwave oven as part of the latter. Measure the second invocation of build_params_numba, when the compilation has been already completed, to see how the compiled function performs.

The second issue is that numba might not be of much help with your code. AFAIK it is designed to speed up numerical algorithms and numpy code. By necessity, namedtuple and dict are Python data structures and numba has to treat them as such; so even though you requested nopython mode, Numba cannot oblige, as it only works when a native data type can be detected for all values in your code (I think — not 100% sure on this point though).

Wrong encoding on CSV file in Python

I am not sure if I am making this question correctly but here's my issue:

I have a .csv file (InjectionWells.csv) that I need to split into columns based on commas. When I do it, it just doesn't work and I can only think might be an encoding but I don't know how to fix it. Can someone shed a light?

As your csv files contain some non-ascii characters also, you need to pass a different encoding. utf-8 can't handle that.

You are calling cmd.exe and not netsh. The string you are passing as argument is not extecuted in the newly created console, you'd need to run cmd /c ... for that.

Just use netsh as your psi.Filename and advfirewall ... as your argument

Install psi

The core \psi infrastructure is built on .NET Standard and therefore runs both on Windows and Linux. Some components and tools are more specific and are available only on one or the other operating system. You can build \psi applications either by leveraging \psi NuGet packages, or by cloning and building the source code. A Brief Introduction. To learn more about \psi and how to build applications with it, we recommend you start with the Brief Introduction tutorial, which will walk you through for some of the main concepts. It shows how to create a simple program, describes the core concept of a stream, and explains how to transform, synchronize, visualize, persist and replay streams from disk. A Video Webinar. If you prefer getting started by watching a presentation about the framework, this video webinar gives a 30 minute high-level overview of the framework, followed by a 30 minute hands-on coding session illustrating how to write a first, simple application. Alternatively, for a shorter (~13 min) high-level overview, see this presentation we did as part of the Tech Minutes series. Samples. If you would like to directly start from sample code, a number of small sample applications are also available, and several of them have walkthroughs that explain how the sample was constructed and point to additional documentation. We recommend you start with the samples below, listed in increasing order of complexity: | Name | Description | Cross-plat | Requirements | | :----------- | :---------- | :--: | :--: | | HelloWorld | This sample provides the simplest starting point for creating a \psi application: it illustrates how to create and run a simple \psi pipeline containing a single stream. | Yes | None | | SimpleVoiceActivityDetector | This sample captures audio from a microphone and performs voice activity detection, i.e., it computes a boolean signal indicating whether or not the audio contains voiced speech. | Yes | Microphone | | WebcamWithAudio for Windows or Linux | This sample shows how to display images from a camera and the audio energy level from a microphone and illustrates the basics of stream synchronization. | Yes | Webcam and Microphone | | WhatIsThat | This sample implements a simple application that uses an Azure Kinect sensor to detect the objects a person is pointing to. | Windows-only | Azure Kinect + Cognitive Services |. Documentation. The documentation for \psi is available in the github project wiki. It contains many additional resources, including tutorials, other specialized topics, and a full API reference that can help you learn more about the framework.
