I have a vector field:

...but when I want to plot the associated streamplot, I get an error:

ValueError: The rows of 'x' must be equal

Here is my code:

I'm creating a machine-learning program to recognize images that are shown on webcam. I've used Google Teachable Machine to generate the model and it works fine.

The matter I'm having issues with is printing the results of a prediction array, when an element of this array achieves a certain value (if it's equal to or more than 0.9 for an element, print a specific message).

Let's say when element prediction[0] >= 0.9 I want to execute print("Up") as it recognizes the image of an arrow facing up or if element prediction[1] >= 0.9 I'd do a print("Down") etc.

But when I try do that using the if statement I am presented with a

Depending upon rendering an SVG either as a whole document or as a single element shows differences in rendering.

I created a simple SVG graphic using Inkscape and want to render it using Python. I decided librsvg was the way to go. This is my SVG, saved from Inkscape as "normal SVG" (without Inkscape-specific extensions).

Below example should update the nodes after select the groups at the bottom. but the select works fine, the nodes on the svg not updated!

This example simulation looks good but drag doesn't work!

I have written a component that paints a picture centered at X,Y. At runtime, the component is moved around with a SetXY(X,Y: integer) procedure.

To acheive this, I calculate what the Left and Top values should be in the paint routine and set them accordingly. And all that works just fine.

But when I try to do the initial positioning at design-time, I cannot position the component by dragging it to the desired location.

When I set either the Left or Top property via the Object Inspector, it works.

I want to filter those rows in data where billingdate lies in a financial year or creating a new column that will tell in which financial year this date is lying.

In this dictionary: keys are financial year and values are starting and ending date of that financial year

I would like to share data (in the simplest case an array of integers) between C and Haskell using Haskell's FFI functionality. The C side creates the data (allocating memory accordingly), but never modifies it until it is freed, so I thought the following method would be "safe":

• After the data is created, the C function passes the length of the array and a pointer to its start.
• On the Haskell side, we create a ForeignPtr, setting up a finalizer which calls a C function that frees the pointer.
• We build a Vector using that foreign pointer which can be (immutably) used in Haskell code.

However, using this approach causes rather non-deterministic crashes. Small examples tend to work, but "once the GC kicks in", I start to get various errors from segmentation faults to "barf"s at this or this line in the "evacuation" part of GHC's GC.

What am I doing wrong here? What would be the "right way" of doing something like this?

I have a C header with the following declarations:

Is it possible to control the order that a dplyr::filter command executes without breaking it into separate filter statements? For example, given the following data frame, and a goal of keeping only rows for groups that participated at least once in 2017:
