问题 I'm currently trying to create a NEAT algorithm to solve FlappyBird but am coming across an error while running my code (see title). Currently I have set up my run function and my eval_genomes functions. I've simplified them to remove the pygame stuff and tried to keep it just to the neat-python relevant bits. I know there are ways I could make this better, but I can someone help in finding how to solve the error I'm seeing below. The error seems to stem from the neat-python module, but I've

问题 I'm updating a package from python 2 to 3 and I cannot get imports to work. Even the easy ones like import math or import os. Everything checks out ok when I run it with idle. If I try to run it through terminal I get a failed to load process message. In debugger it runs through a few file paths and always gives the same error. I've read a lot of documentation on imports and I'm fairly certain the imports are correct. import os ... import logging ... ... import argparse log = logging

问题 I'm getting an error: self.button.set(str(self)) AttributeError: 'Button' object has no attribute 'set' I can't figure out what to change to make it work. Here is the important parts of the code: class Cell: def show_word(self): """ Shows the word behind the cell """ if self.hidden == True: self.hidden = False else: self.hidden = True self.button.set(str(self)) class Memory(Frame): def create_widgets(self): """ Create widgets to display the Memory game """ # instruction text Label(self, text

问题 Firstly, apologies for how obvious these two questions seem to be; I'm very very new to this and don't have a clue what I'm doing. I'm trying to write something to apply the Scipy function for spline interpolation to an array of values. My code currently looks like this: import numpy as np import scipy as sp from scipy.interpolate import interp1d x=var x1 = ([0.1,0.3,0.4]) y1 = [0.2,0.5,0.6] new_length = 25 new_x = np.linspace(x.min(), x.max(), new_length) new_y = sp.interpolate.interp1d(x, y

问题 I recently installed pyusb for this project, which is trying to attempt at writing to a USB LED Message Board and received this error: AttributeError: 'module' object has no attribute 'backend' I don't know why this is, I checked the pyusb module files and it clearly has a folder named "backend" and inside has the correct files. Here's all of my code: import usb.core import usb.util import sys backend = usb.backend.libusb01.get_backend(find_library=lambda C: "Users\absolute\Desktop\libusb
