我正在使用python +硒来实现Web浏览器自动化，并收到此错误。
DevTools listening on ws://127.0.0.1:57671/devtools/browser/8a586f7c-5f2c-4d10-8174-7a7bf50e49b5
[5096:1196:0909/183254.362:ERROR:mf_helpers.cc(14)] Error in dxva_video_decode_accelerator_win.cc on line 517
当程序到达代码的这一部分时，就会出现问题：-
def send_comments(driver):
add_comments = driver.find_elements_by_class_name('add')
comments = driver.find_elements_by_xpath("//form[@class='addCommentexpand']//textarea[contains(@placeholder,'Add a comment')]")
submit_comments = driver.find_elements_by_xpath("//button[text()='Comment']")
i = 0
for add, comment, submit in zip(add_comments, comments, submit_comments):
print("comment begins")
add.click()
print("+add comment clicked")
comment.click()
print("comment textbox clicked")
comment.send_comments("Amazing Art")
print("text typed")
submit.click()
print("comment submited")
i += 1
if i > 5:
driver.close()
send_comments(driver)
它也没有登录控制台。谁能说出问题所在吗？

@AndreaCardaci提到在无头模式下使用 Google Chrome
通常的示例代码每次都在单独的上下文中的新的一次性选项卡中运行（认为它是隐身配置文件）。
为了从Chrome 62开始获取浏览器版本，浏览器目标URL是在运行时生成的，可以通过 <?xml version="1.0" encoding="utf-8"?>

android:text="Lorem ipsum is a pseudo-Latin text used in web
design, typography, layout, and printing in place of English to emphasise
design elements over content. It's also called placeholder (or filler)
text. It's a convenient tool for mock-ups. It helps to outline the
visual elements of a document or presentation, eg typography, font, or
layout. Lorem ipsum is mostly a part of a Latin text by the classical author
and philosopher Cicero. Its words and letters have been changed by addition
or removal, so to deliberately render its content nonsensical; it's not
genuine, correct, or comprehensible Latin anymore. While lorem ipsum's
still resembles classical Latin, it actually has no meaning whatsoever. As
Cicero's text doesn't contain the letters K, W, or Z, alien to latin,
these, and others are often inserted randomly to mimic the typographic
appearence of European languages, as are digraphs not to be found in the
original."/>

端点获取并回退到 {{1} } （如果不存在）。
以下是相关代码：
/json/version此外，根据Obtain the browser target URL (ws://localhost:9222/devtools/browser/...) programmatically，在 /devtools/browser 字段的const CDP = require('chrome-remote-interface');
async function doInNewContext(action) {
// fetch the browser version (since Chrome 62 the browser target URL is
// generated at runtime and can be obtained via the '/json/version'
// endpoint, fallback to '/devtools/browser' if not present)
const {webSocketDebuggerUrl} = await CDP.Version();
// connect to the DevTools special target
const browser = await CDP({
target: webSocketDebuggerUrl || 'ws://localhost:9222/devtools/browser'
});
// create a new context
const {Target} = browser;
const {browserContextId} = await Target.createBrowserContext();
const {targetId} = await Target.createTarget({
url: 'about:blank',
browserContextId
});
// connct to the new context
const client = await CDP({target: targetId});
// perform user actions on it
try {
await action(client);
} finally {
// cleanup
await Target.closeTarget({targetId});
await browser.close();
}
}
// this basically is the usual example
async function example(client) {
// extract domains
const {Network, Page} = client;
// setup handlers
Network.requestWillBeSent((params) => {
console.log(params.request.url);
});
// enable events then start!
await Promise.all([Network.enable(), Page.enable()]);
await Page.navigate({url: 'https://github.com'});
await Page.loadEventFired();
}
doInNewContext(example);
上可以使用端点。因此，或者，如果您使用选项http://127.0.0.1:9222/json/version启动chrome，则将端口和端点都写入浏览器中的 DevToolsAcivePort 文件中个人资料文件夹。
此错误不会影响您的webSocketDebuggerUrl，您可以暂时忽略该错误。

基于hide chromeDriver console in python中的Chanticleer
在您的Python文件夹中，找到并编辑此文件：
Lib\site-packages\selenium\webdriver\common\services.py
通过以下方式添加创建标记来编辑Start（）函数：creationflags=CREATE_NO_WINDOW
from win32process import CREATE_NO_WINDOW
def start(self):
"""
Starts the Service.
:Exceptions:
- WebDriverException : Raised either when it can't start the service
or when it can't connect to the service
"""
try:
cmd = [self.path]
cmd.extend(self.command_line_args())
self.process = subprocess.Popen(cmd, env=self.env,
close_fds=platform.system() != 'Windows',
stdout=self.log_file, stderr=self.log_file, creationflags=CREATE_NO_WINDOW)
except TypeError:
raise
使用python3.7和硒3.141.0对我来说非常合适

试试这个：
settings.py.答案 3 :(得分：-1)
这是工作：
import warnings
warnings.filterwarnings("ignore", category=DeprecationWarning)
...
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--log-level=3")
browser = webdriver.Chrome(chromedriver_path, chrome_options=chrome_options)
