I'm trying to learn three.js and I'm trying to move a cube with animationmixer. https://discoverthreejs.com/book/first-steps/animation-system/ I'm trying to run the codes in this link but it's not working. I'm looking at the console to see why, but the error doesn't appear. I don't understand why it's not working.

You will need to update the mixer every frame in the loop.

See the #update-the-animation-in-the-loop section in the chapter you linked.

If you edit your animate function like this it should work:

QUESTION

QtWidget is not showing

Asked 2021-Dec-15 at 21:30

I am trying to use PyQt5 to show two widgets, the first one is a plot of sin, cos and tan function. I am using the pyqtgraph and used the code that was found in the answer of this question. I am also using another widget that draws a cube using PyOpenGL, by taking the example found in this link. I am trying to show this two widgets in one main widget, which is the main window. My approach is the following

Take a main widget.
In the main widget, use a QVBoxLayout()
In the QVBoxLayout, at two widgets mentioned above

But when I am running the code, only the plot that is using the pyqtgraph is shown but not the cube that is drawn using PyOpenGL. After a little bit debugging, I was able to find out that the height of the cube widget is setting to 0 by default. I am not sure why this is hapenning. I tried calling glWidget.resize(640,480). But it didn't work. I am new on working with PyQt and PyOpenGL. I think I am missing some details that will allow the height of the glWidget to be greater than 0, if my assumption is correct. Also I am not sure if this is actually possible to do. My current code is given below, it is a little bit messy.

ANSWER

Answered 2021-Dec-15 at 21:30

It seems that QGLWidget (which, by the way, is deprecated, and QOpenGLWidget should be used instead) doesn't implement sizeHint(), so it returns an invalid size (QSize(-1, -1)), which means that the widget can be possibly resized to a 0 width and/or height.

Since the plot widget has an expanding size policy (and dynamically reimplements sizeHint()) the result is that the gl widget is completely hidden, having 0 height.

A possible solution is to add the widgets with a proper stretch argument to the layout.

If you want both widgets to have the same height, you can do the following:

How to call a function inside the code to return the degree of a polynomial?

Asked 2021-Oct-14 at 22:37

In haskell's Poly package polynomials like x**2 + -1 are represented by [ -1, 0, 2] so for calculate the degree of a polynomial, I need to calculate the length of the polynomial list - 1.

This is what I have done:

ANSWER

Answered 2021-Oct-14 at 22:37

I haven’t read this book, but I get the impression that it doesn’t intend for you to use a third-party package here.

Instead, directly use a list. A list of type [k] and length n can represent a polynomial with n coefficients of type k, in order from least significant (x⁰) to most significant (x^{(n − 1)}). Then one way of calculating the degree is like you said, simply the length of such a list less one:

Calling a Python C extension blocks all Django processes/users

Problem

I have written a Python C extension (ftaCalculate) in order to improve the performance of a given function that was previously written in pure Python. I have been able to increase the execution speed by a factor of x10, so no problem on this site.

As @Kemp suggested, the problem was on the Global Interpreter Lock (GIL). The solution has been to release the GIL when I am not using any Python object and reacquire it afterwards.

Following the details of Releasing the GIL from extension code section, I have put the corresponding C code between the following two lines:

Can't run uvicorn --version

Asked 2020-Oct-27 at 19:55

I'm trying FastAPI but I can't even run the Hello World example. I've installed both uvicorn and fastapi with a venv and requirements.txt, also I'm running Python 3.5 (maybe that's the issue?)

The issue should be something with uvicorn because I can't run --help or --version

...

ANSWER

Answered 2020-Oct-27 at 19:54

Surely with Python 3.5, FastAPI won't work.

FastAPI homepage:

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints.

uvicorn (from https://github.com/encode/uvicorn):

Requirements: Python 3.6+ (For Python 3.5 support, install version 0.8.6.)

I guess you should update Python to 3.6 at least. pyenv should help.

Answered 2020-Oct-09 at 15:33

I'm going to add my comment as an answer, because this Telerik thread confirms (and references the same error you are encountering) that you'll need a later version of Kendo to have support for .NET Core 3.1.

This quote here from the thread linked above - about .NET Core 3.0 requiring a later version than you are using:

Artem, that is correct. Only the latest version of the UI for ASP.NET Core suite (2019.3.1023) offers official support for .Net Core 3.0.

Jerry, feel free to contact us if you have any further questions on the .Net Core 3.0 integration.

Regards, Veselin Tsvetanov

R3 2019 is the first release that mentions full support for .NET Core 3.1.

One approach is to generate the OpenApi schema as described in the documentation Extending OpenAPI. After the generation, remove the X-Remote-User from the schema. In the configuration could be a flag that the application it is behind a reverse proxy to execute the code conditionally:
