QUESTION
I face the following problem with GEKKO: some parameters (.Param) are changing (others not) when solving a model and I cannot determine why.
Background: I am currently trying to translate code from EViews (see gennaro.zezza.it) to python. I use GEKKO to simulate a system consisting out of 11 equations (for now). I do want to use parameters (instead of constants which seem to work perfectly fine) as I need to ('exogenously') change their value over time (and thus need an array).
Example: In the following example, an 'economic system' reacts to new government expenditures. Here, I particularly face problems with "m.alpha1" and "m.alpha2" - if they are introduced as ".Param" their value will change to 1.0 (instead of 0.6 and 0.4) when solving the model. How can I stop GEKKO from doing this? (Again, I want to be able to change, e.g., alpha1 to 0.7 after time x. E.g., lower and upper bounds won't help here.)
Thanks for your help!!

I have to make a program that generates stars in random locations of random size. My code already plots the stars in random locations, but I can't manage to randomly change their sizes. I tried assigning a size factor to each point to alter the distance between them but the stars came out all messed up. Is there a scaling method I can use?
Here is what I have so far, it plots the stars in random locations.
...ANSWER
Answered 2021-May-30 at 20:00Here's an example of how to change the size of a Polygon. I drew squares but any Shape will work.
- just create a scale instance of an
AffineTransformand use that to scale the Shape. - I used
ThreadLocalRandomto randomly choose the scale to be applied. I always copy the original polygon(template) and then scale that.

I'm try to loop 2 query inside one table . both query had 10 records . so i put my first foreach (or looping) before TR tag ..
here is example of the table that i want to create :
...ANSWER
Answered 2021-May-28 at 04:15Yep, your logic is missing something because the second loop is running within the first loop, so you're creating a lot of TDs within the same TR.
In order to achieve what you want, I suggest merging the two arrays, then looping a single array.

so im getting an error message using the while loop and i cant figure out why. it says it expects a ')' before 'matrix' . im new to this so its probably an easy fix. The idea is to repeat the scanf till the matrix is filled with '10'. here is the code:

Answered 2021-Apr-22 at 01:21As mentioned above, you need to add logical operators between your conditions.
So the code would look like this for the or operator.

I'm trying to replicate a report using RMarkdown/LaTeX. Is it possible to add a letterhead to the top of a page in a similar way to the image I've attached? Hoping to find a solution where I can have a letterhead with a logo in it (and where I can easily customise the text and color of the letterhead too).
TIA

This piece of code is used to make an animated graph. The var xd and yd is the data for the x- axis and y-axis. So I have automated this by +1 to xd, which repeats every 1 second use threads. Which unfortunately results with an error: 'UnboundLocalError: local variable 'xd' referenced before assignment'. I have tried many answers but some result with, 'define xd' or 'syntax error'.
...ANSWER
Answered 2021-Apr-06 at 02:21It seems to me that you want to define xd as a global variable
QUESTION
I have a matplotlib plot where certain points get annotated. I have worked out how to do the annotations themselves, including arrows and everything. However, I need to add a line to each annotation, next to the text of the annotation. It should run in parallel to the text, with a certain offset from the text in points. The length of the line is based on a percentage value, that each annotated point has. Ideally I would like a line that's always the same length (roughly 15 text characters, which is the max length of the text in the annotations) but has a let's say red and grey portion, based on the percentage value mentioned. Any help or suggestions is greatly appreciated.
Edit: Here is a minimum example of some mock data points:
...ANSWER
Answered 2021-Apr-03 at 20:26You can use plt.Rectangle to draw the bars — first a grey one that is the height of the entire bar, and then the red bar that is a percentage of the height of the entire bar.
However, since the width and length parameters of the rectangle are in units of the x- and y-coordinates on the plot, we need to be able to access the coordinates of the text annotations you made.
You set the annotation coordinates using textcoords="axes fraction" which makes it difficult to access the starting and ending coordinates for the rectangle in x- and y-coordinates, so instead I defined some constants x_min, x_max, y_min, y_max for the limits of the plot, and then calculated the coordinates for your text annotations directly from the tspace list as well as the bar annotation.
The percentage of red space for each bar can be set in a list so that's it's generalizable.

I have a Flink job that runs well locally but fails when I try to flink run the job on cluster. It basically reads from Kafka, do some transformation, and writes to a sink. The error happens when trying to load data from Kafka via 'connector' = 'kafka'.
