問(wèn)題描述
我嘗試使用 selenium 和 webdriver_manager.chrome 抓取特定網(wǎng)站，而我的代碼完全抓取了該網(wǎng)站的元素.但是爬取后，控制臺(tái)窗口出現(xiàn)如下錯(cuò)誤信息.
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
當(dāng)我第一次找到它時(shí)，我取消了 chrome 的硬件硬件加速也沒(méi)有解決問(wèn)題.
When I first found it, I unchecked Hardware hardware accleration of chrome also it didn't solve the problem.
推薦答案
測(cè)試環(huán)境
Windows 操作系統(tǒng)，Chromedriver 版本 89，無(wú)頭模式
Windows OS, Chromedriver vesion 89, headless mode
解決方案
我不確定這是否可以解決您的問(wèn)題，因?yàn)殄e(cuò)誤消息略有不同.
I am not certain that this can be a solution for your question, since the error message is slightly different.
我沒(méi)記錯(cuò)，錯(cuò)誤消息 Passthrough is not supported, GL is swiftshader 在 Chromedriver 版本 89 之后顯示為錯(cuò)誤(但不確定)[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 的情況下，需要 --headless 和 --disable-gpu 選項(xiàng)以使 chromedriver 以無(wú)頭模式工作 [2].由于錯(cuò)誤 [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].
如果同時(shí)刪除
--headless和--disable-gpu選項(xiàng)，則不會(huì)出現(xiàn)錯(cuò)誤消息.但是，chromedriver 不再作為無(wú)頭模式工作.
The error message does not appear if both
--headlessand--disable-gpuoptions are removed. However, the chromedriver does not work as a headless mode anymore.
在我的情況下，錯(cuò)誤消息不會(huì)影響無(wú)頭 chrome 的操作.正如我發(fā)現(xiàn)的那樣，通常情況下，Chrome 會(huì)在沒(méi)有 GPU 的情況下恢復(fù)工作.但是，為了獲得一致的結(jié)果，遙測(cè)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]."
我還應(yīng)用了 --disable-software-rasterizer 選項(xiàng)來(lái)禁用 WebGL [5].無(wú)頭操作下不再顯示錯(cuò)誤信息.
I've additionally applied --disable-software-rasterizer option to disable WebGL [5]. The error message does not show anymore under the headless operation.
