Is it possible to draw 2D and 3D contour plot like this in python. Sorry I couldn’t provide much detail on the plot in terms of mathematical equations and all. Answer Use plot_surface along with contour to project the contour. It is not limited to the Z plane; you can do this to the X and Y planes as well.

Shuffling two 2D tensors in PyTorch and maintaining same order correlation
Is it possible to shuffle two 2D tensors in PyTorch by their rows, but maintain the same order for both? I know you can shuffle a 2D tensor by rows with the following code: To elaborate: If I had 2 tensors And ran them through some function/block of code to shuffle randomly but maintain correlation and produce something like the
python 3d list manipulation
I have a 3d list aa = [[[2, 3, 4, 5], [ 6, 7, 8, 9]], [[11, 12, 14, 15]]], which consists of two 2d lists how do I get this result [[2, 6], [11]] the first element of each sub list. gives [2,6,11] Answer You can do it with a list comprehension: Output:
Show better representation of small values of 2D plot
I am trying to make a 2D plot of a function 1/(xy) but the y values vary from 3 orders of magnitude which makes the graph look unreadable. On top of that, I am trying to emphasize the small values of 1/(xy) i.e. when x and y are big. Here is my linear attempt: You see two points on both
How do you prevent “unhashable type ‘list'”?
So, I was making a simple 2D game in pygame, and was making the map (following a tutorial video, don’t judge me, I’m new to pygame) and using replit.com, and that error showed up in the console. here’s my code for it: if anyone has any suggestions for changing my code, please say, and I am sticking with replit.com Answer
how to move specific part of a 2d array to either left right up or down?
I know that you can move an array with NumPy so if you use np.roll you can shift array to right or to the left. I was wondering how to move a specific set of values with in the array to either left right up or down. for example if I wanted to move what is circled in red to
fitting closed curve to a set of noisy points
This is my set of data, where I would like to fit a closed curve to, just like this post here is the visualized dataset: However, these are the results I got no matter how I sort my array. I pinned a few problems about my dataset but don’t know how to deal with them: Many x and y values
How to define a 2D array of (x,y) coordinates
I have a 2d space of (x,y) coordinates that I want to model in python and want to know a way to define the 2d space in python where I can assign multiple values to a point (x,y). Later values at coordinates will be changed based on some coordinate dependent calculations. I thought about using numpy array to create the
pygame – How do I change a variable while it is being used?
I’m making a simple top-down game with moving and collision between player and walls, using pygame. I made my code so that when keys[pygame.K_LSHIFT] is True during the pygame.key.get_pressed at the state of the keyboard when it’s called, block_speed changes to 5 instead of 3. So it works and when I hold SHIFT and move with WASD keys at the
