解决Selenium在运行中出现浏览器页面崩溃，最后导致丢失session id的问题。

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:

• Add the following chrome_options:

chrome_options.add_argument('--no-sandbox')         
1

• 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.

• An example:

• sudo mount -t tmpfs -o rw,nosuid,nodev,noexec,relatime,size=512M tmpfs /dev/shm
  1

• It also works if you use -v /dev/shm:/dev/shm option to share host /dev/shm

• 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')
