问题 I have a pycuda program here that reads in an image from the command line and saves a version back with the colors inverted: import pycuda.autoinit import pycuda.driver as device from pycuda.compiler import SourceModule as cpp import numpy as np import sys import cv2 modify_image = cpp(""" __global__ void modify_image(int pixelcount, unsigned char* inputimage, unsigned char* outputimage) { int id = threadIdx.x + blockIdx.x * blockDim.x; if (id >= pixelcount) return; outputimage[id] = 255 -

问题 As a followup to my previous question about calling an async function from a synchronous one, I've discovered asyncio.run_coroutine_threadsafe . On paper, this looks ideal. Based on the comments in this StackOverflow question, this looks ideal. I can create a new Thread, get a reference to my original event loop, and schedule the async function to run inside the original event loop while only blocking the new Thread. class _AsyncBridge: def call_async_method(self, function, *args, **kwargs):

问题 I was checking the documentation of list.index() method in python, what I saw is : >>> help(list().index) Help on built-in function index: index(value, start=0, stop=9223372036854775807, /) method of builtins.list instance Return first index of value. Raises ValueError if the value is not present. When I ran the code below gave me some error. >>> l=[1,2,3,43,45,5,6,6] >>> l.index(43,start=1) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: index() takes no

问题 I have some data frames I am trying to upload to a database. They are lists of values but some of the columns have the string 'null' in them and so this is causing errors. so I would like to use a function to remove these 'null' strings and am trying to use replace to back fill them below: df.replace("null", method = bfill) but it is giving me the error message: ParserError: Error tokenizing data. C error: Expected 1 fields in line 4, saw 2 I have also tried putting "bfill" instead and it
