error in anaconda virtual environment

[Ocamyyyy]

after installing the cv_bridge with python3 of Ubuntu18.04, I can use cv_bridge normally by the system's python3. However, when I change the interpreter to a virtual environment python3.7 in anaconda and even remember sourcing the building result of cv_bridge, the result of code "from cv_bridge.boost.cv_bridge_boost import getCvType" is segment error. `Python 3.7.0 (default, Oct 9 2018, 10:31:47) [GCC 7.3.0] :: Anaconda, Inc. on linux Type "help", "copyright", "credits" or "license" for more information.

from cv_bridge.boost.cv_bridge_boost import getCvType 段错误 (核心已转储) `

Do you have some more details of ros versions, and whether you're using a source build or binary build?

Two things to note though:

• Ubuntu 18.04 is no longer supported by any of the ROS distros. Things will likely still work if you are using binaries, or building the correct branch from source.
• ROS installations typically rely on the Python version that comes pre-installed with the operating system, so if you're lucky, things may work with a different python version.
