问题描述

我尝试使用 selenium 和 webdriver_manager.chrome 抓取特定网站，而我的代码完全抓取了该网站的元素.但是爬取后，控制台窗口出现如下错误信息.

I tried crawling a specific site using selenium and webdriver_manager.chrome, and my code crawled elements of that site totally. But after crawling, the following error message appears in the console window.

ERROR:gpu_init.cc(426) Passthrough is not supported, GL is disabled

当我第一次找到它时，我取消了 chrome 的硬件硬件加速也没有解决问题.

When I first found it, I unchecked Hardware hardware accleration of chrome also it didn't solve the problem.

解决方案

测试环境

Windows 操作系统，Chromedriver 版本 89，无头模式

Windows OS, Chromedriver vesion 89, headless mode

解决方案

我不确定这是否可以解决您的问题，因为错误消息略有不同.

I am not certain that this can be a solution for your question, since the error message is slightly different.

我没记错，错误消息 Passthrough is not supported, GL is swiftshader 在 Chromedriver 版本 89 之后显示为错误(但不确定)[1].

As I remember correctly, the error message Passthrough is not supported, GL is swiftshader has been shown after the Chromedriver version 89 as a bug (but not certain) [1].

在 Windows 的情况下，需要 --headless 和 --disable-gpu 选项以使 chromedriver 以无头模式工作 [2].由于错误 [3]，Linux 似乎也需要 --disable-gpu.

In case of Windows, --headless and --disable-gpu options are required to make the chromedriver work as a headless mode [2]. It seems like --disable-gpu is also required for Linux because of the bug [3].

  1. 如果同时删除 --headless 和 --disable-gpu 选项，则不会出现错误消息.但是，chromedriver 不再作为无头模式工作.

  1. The error message does not appear if both --headless and --disable-gpu options are removed. However, the chromedriver does not work as a headless mode anymore.

在我的情况下，错误消息不会影响无头 chrome 的操作.正如我发现的那样，通常情况下，Chrome 会在没有 GPU 的情况下恢复工作.但是，为了获得一致的结果，遥测需要 GPU [4]."

In my case, the error message does not affect the operation of a headless chrome. As I found, "Normally, Chrome would just fall back to work without GPU. However, for consistent results, Telemetry requires the presence of GPU [4]."

我还应用了 --disable-software-rasterizer 选项来禁用 WebGL [5].无头操作下不再显示错误信息.

I've additionally applied --disable-software-rasterizer option to disable WebGL [5]. The error message does not show anymore under the headless operation.
