This is the code that I have used. Now I do not really know where did I go wrong as I am new to such things. As an overview of what I am trying to do is that I am trying to classify where there is an attack or no. I gave ‘Y’ as my […]

How to add collision detection to 2d objects in ursina?

Hi i was wondering how to add collision detection to 2d entitys in ursina. I am a beginner so this is very difficult for me. Here’s my code attached: from ursina import * def update(): if held_keys[‘a’]: player1.x -= 1 * time.dt if held_keys[‘d’]: player1.x += 1 * time.dt if held_keys[‘w’]: player1.y += 1 * […]

Why do my_list *= 2 and my_list = my_list * 2 produce different results in a function that takes my_list as an argument?

Although both functions are logically doing the same thing i.e. doubling the list by itself, why does one function modify the original list and the other doesn’t? The only difference visible in the code is that func2() uses short-hand notation for doubling while func1() doesn’t. Aren’t my_list *= 2 and my_list = my_list * 2 […]

statsmodel summary col getting a latex key error?

I’ve been getting a key error when using the summary_col function. import statsmodels.api as sm from statsmodels.iolib.summary2 import summary_col Y = [0,1,0,0,1,1,1] X = [5,10,15,20,25,2,7] logit = sm.Logit(Y,X) fit = logit.fit() print(fit.summary()) logit_output = summary_col([fit],stars=True) print(logit_output.as_latex()) gets me a "Key Error: ‘\m’". Surprisingly, fit.summary().as_latex() does not return this error.

Is a true RNN auto encoder possible with Keras/TF

I want to get some encodings for temporal data (with highly varying number of timesteps). The dataset is of the format: array<TemporalSample = list, SAMPLE_COUNT> (where array is fixed size and list is variable). The TemporalSamples are simply lists of size TemporalSample::timesteps Currently, I use a standard RNN network of the form: model = keras.Sequential() […]
