any one knows how to fix it ?

It looks like the problem is with the .so being compiled for ubuntu but trying to be loaded into osx. Did you start the colab kernel from inside of docker?

Encountered the same problem. The question is because of docker? Do I have to use docker to build?

You don't have to use docker, but then it is up to you to get the correct environment configuration. If you're using a mac and not using docker we have not tested that setup and cannot give any advice regarding it.
