未知错误:会话因页面崩溃而从未知错误中删除:无法通过ChromeDriver Selenium崩溃的选项卡确定加载状态 [英] unknown error: session deleted because of page crash from unknown error: cannot determine loading status from tab crashed with ChromeDriver Selenium
问题描述
我正在使用使用Python和Selenium的InstaPy.我每个Cron都会启动脚本，并且有时会崩溃.因此，它确实是不规则的，有时运行得很好.我也已经在GitHub Repo上发布了消息，但是在那里没有得到答案，所以我现在在这里问是否有人知道为什么.
I'm using InstaPy which use Python and Selenium. I start the script per Cron and from time to time it crashes. So it'r really irregular, sometimes it runs well through. I'v posted on GitHub Repo as well already but didn't get an answer there, so i'm asking here now if someone has an idea why.
这是一台数字海洋ubuntu服务器，我在无头模式下使用它.驱动程序版本在日志中可见.这是错误消息:
It's a digital ocean ubuntu server and i'm using it on headless mode. The driver version are visible on the log. here are error messages:

有人知道原因可能是什么以及如何解决?
Any idea what the reason could be and how to solve it?
推荐答案
尽管您看到以下错误:
Error occurred while deleting cookies from web browser!
b'Message: invalid session id\n (Driver info: chromedriver=2.44.609551 (5d576e9a44fe4c5b6a07e568f1ebc753f1214634),platform=Linux 4.15.0-42-generic x86_64)\n'
主要例外是:
selenium.common.exceptions.WebDriverException: Message: unknown error: session deleted because of page crash
from unknown error: cannot determine loading status
from tab crashed
您的代码试验将为我们提供一些出了什么问题的线索.
Your code trials would have given us some clues what going wrong.
对此问题有多种解决方案.但是根据 UnknownError:由于标签页崩溃导致会话被删除， 可以通过以下任一解决方案解决:
There are diverse solution to this issue. However as per UnknownError: session deleted because of page crash from tab crashed this issue can be solved by either of the following solutions:
-
添加以下
chrome_options:
chrome_options.add_argument('--no-sandbox')
由于/dev/shm太小，Chrome似乎在某些页面的Docker容器中崩溃.因此，您可能必须修复较小的/dev/shm大小.
Chrome seem to crash in Docker containers on certain pages due to too small /dev/shm. So you may have to fix the small /dev/shm size.
一个例子:
sudo mount -t tmpfs -o rw,nosuid,nodev,noexec,relatime,size=512M tmpfs /dev/shm
如果您使用-v /dev/shm:/dev/shm选项共享 host /dev/shm
It also works if you use -v /dev/shm:/dev/shm option to share host /dev/shm
使其生效的另一种方法是将chrome_options添加为 --disable-dev-shm-usage .这将强制Chrome使用/tmp目录.尽管这会减慢执行速度，因为将使用磁盘而不是内存.
Another way to make it work would be to add the chrome_options as --disable-dev-shm-usage. This will force Chrome to use the /tmp directory instead. This may slow down the execution though since disk will be used instead of memory.
chrome_options.add_argument('--disable-dev-shm-usage')
从选项卡崩溃是与 Chromium小组进行的WIP( Work In Progress )工作了很长一段时间，这与 Linux有关尝试始终将/dev/shm用于不可执行的内存.这里是参考:
from tab crashed was WIP(Work In Progress) with the Chromium Team for quite some time now which relates to Linux attempting to always use /dev/shm for non-executable memory. Here are the references :
- Linux:Chrome/Chromium SIGBUS/Aw，Snap！在小型/dev/shm 上
- /dev/shm太小，Chrome崩溃/无法加载，并且不能覆盖位置
- 根据评论61#问题736452 似乎已经安装了 Chrome v65.0.3299.6
- Linux: Chrome/Chromium SIGBUS/Aw, Snap! on small /dev/shm
- Chrome crashes/fails to load when /dev/shm is too small, and location can't be overridden
- As per Comment61#Issue 736452 the fix seems to be have landed with Chrome v65.0.3299.6
