当使用Python 2.7 urllib2从API检索数据时,我收到错误[Errno 104] Connection reset by peer.什么导致错误,以及如何处理错误,以便脚本不会崩溃？

是否可以Meteor.Collections从2个不同的mongdb数据库服务器中检索数据？

使用 Selenium 后，我决定尝试一下，undetected-chromedriver所以我使用它安装了它

 pip install undetected-chromedriver

但是，运行这个简单的脚本

import undetected_chromedriver.v2 as uc

options = uc.ChromeOptions()
options.add_argument('--no-sandbox')

driver = uc.Chrome(options=options)
with driver:
    driver.get('https://google.com') 

给出错误

selenium.common.exceptions.WebDriverException：消息：未知错误：无法从无法访问的 chrome 连接到 127.0.0.1:37541 的 chrome

使用常规 Selenium 没有问题

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument("--no-sandbox"); # Bypass OS security model

driver = webdriver.Chrome(options=options)
with driver:
    driver.get('https://google.com') 

这是回溯

由于还不熟悉 Typescript，我正在尝试使用Typescript 在我的 React 应用程序中为我的 Recharts 图表创建自定义工具提示内容。@types/recharts已作为 a 之一安装devDependencies。

但是，当我定义CustomTooltip如下所示的函数时，Typescript 抛出错误

绑定元素“active”隐式具有“any”类型。TS7031

我们该如何解决这个问题呢？

const CustomTooltip = ({ active, payload, label }) => {
    if (active) {
        return (
        <div className="custom-tooltip">
            <p className="label">{`${label} : ${payload[0].value}`}</p>
            <p className="desc">Anything you want can be displayed here.</p>
        </div>
        );
    }

    return null;
}

return (
    <ComposedChart data={data}>
        ...
        <Tooltip content={<CustomTooltip />} />
    </ComposedChart>
)

尝试定义接口，但出现另一个错误

类型“{}”缺少类型“ICustomToolip”中的以下属性：活动、有效负载、标签 TS2739

interface ICustomToolip {
    active: any;
    payload: any;
    label: any;
}

使用num_workers=32for运行 PyTorch 训练程序时DataLoader，htop显示 33 个 python 进程，每个进程具有 32 GBVIRT和 15 GB 的RES.

这是否意味着 PyTorch 训练使用了 33 个进程 X 15 GB = 495 GB 的内存？htop显示只有大约 50 GB 的 RAM 和 20 GB 的交换在整个机器上使用，具有 128 GB 的 RAM。那么，我们如何解释这种差异呢？

是否有更准确的方法来计算主 PyTorch 程序及其所有子 DataLoader 工作进程使用的 RAM 总量？

谢谢

是否可以将 DAG 设置为启用，但直到下次计划运行时才首次运行？
