I have defined the following function

can be simplified as the following implementation:

QUESTION

I'm currently learning/working with classes in Python 3.10.2 as of writing this. What I am trying to achieve is to create a class instance which is an attribute within another class.

Here is some code I've been working on to help demonstrate my point.

- A way I can achieve this without having to allocate the pre-determined values within the Tyre class?

A possible solution might be to pass the arguments for `Tyre`

when initializing the `Vehicle`

QUESTION

I have trouble with my N qubit wavefunction. I try to prepare a state `psi = a|0> + b*exp(2i\pi\theta)|1>`

, and I wanted to check if the values for `b*exp(2i\pi\theta)`

were well distributed.

Here is how I got my wavefunction :

...ANSWER

Answered 2022-Mar-10 at 08:53You need to make the output array `psi`

"complex aware". An easy way is to fill it with complex values instead of `None`

objects:

QUESTION

I am "including" a .tex file. I get the error "TeX capacity exceeded, sorry [input stack size=5000].@nomath ...e@font@warning etc." The error is located by latex in the line that says

\pic[current plane, draw,fill=orange!50,fill opacity=.5, text opacity=1,"\footnotesize $\phi$", angle eccentricity=2.2]{angle=ketplus--origin--psiProjectedEquat}; %je nachdem, ob der Psi Pfeil links oder rechts von der z-Achse ist, muss man die Reihenfolge bei "angle=" umkehren }

I should point out that the file that is "included" works when compiled on its own (where the preamble isn't in the masterfile but in the file itself. It seems that the `\usepackage[ngerman]{babel}`

in the masterfile causes the problem.

MWE:

"file.tex":

...ANSWER

Answered 2022-Mar-03 at 14:56As you've noticed, the combination of your tikz picture and babel causes the problem. You can fix this by loading the babel tikz library:

QUESTION

As mentioned above, the function below works, however its very slow. I am very interested in using faster/optimised numpy (or other) vectorized alternatives. I have not posted the entire script here due to it being too large.

My specific question is - are there suitable numpy (or other) functions that I can use to 1) reduce run time and 2) reduce code volume of this function, specifically the **for** loop?

Edit: mass, temp, U and dpdh are functions that carry out simple algebraic calculations and return constants

...ANSWER

Answered 2022-Feb-24 at 13:43For improving the speed, you can see Numba, which is useable if you use NumPy a lot but not every code can be used with Numba. Apart from that, the formulation of the equation system is confusing. You are solving 3 equations and adding the result to a single `dydt`

list by 3 elements each. You can simply create three lists, solve each equation and add them to their respective list. For this, you need to re-write `my_system`

as:

QUESTION

I'm having trouble understanding an error message I'm getting from my GEKKO model.

For context, this model is supposed to optimize the gas spring force and dimension parameters of a gas-spring assisted door to minimize the operator force required to close the door. My intent is to calculate the required force at a series of angles between 0 and 90 degrees, then sum the absolute value of the force at all angles and minimize that value. There is also a constraint on the gas spring length so the optimization doesn't come up with unrealistic dimension parameters. I've defined the force and other values that need to be computed at each angle as lists of Intermediate variables.

The error appears to be related to one of these lists of Intermediate variables, but I don't know how to interpret "Position: 2" in the error message, let alone "Error in syntax of function string". I've searched in some other answers on here, but I haven't found a clear answer on how to use this position information to troubleshoot the model. What is the message trying to tell me?

...ANSWER

Answered 2022-Jan-15 at 05:44One way to locate the error is to open the run directory and inspect the text model file `gk_model0.apm`

.

QUESTION

I want to have text printed out on the condition that the mouse positions hover over a certain coordinate range for both *x* and *y* coordinates. However, the text can not print even if I state in the code that the text should be printed if its on a certain coordinate range. Can anyone offer me some advice towards what I should be doing? Any help can be appreciated.

**The code to print the text is after the "// Gamma" comment**

ANSWER

Answered 2022-Jan-10 at 18:28As noted above the if(keyPressed) needs to be removed. The following works on my system. I changed the images to some that I had for testing purposes; you'll need to change them back for your setup. I also added an extra display function to simplify things a little. There is likely more optimization that could be done. Make sure that the _imgW and _imgH values are correct for your images.

I am trying to make a problem more reactive to new inputs here is where the error is given
