PyCharm autocomplete and highlight syntax doesn't work with ssh interpreter.

I have a docker container which runs on a server and can accessible via ssh. This container is PyTorch container and it is used as Python kernel. However, when I connected remote host and set the project interpreter to docker interpreter over ssh, the code editor doesn't highlight syntax and autocomplete code. I am able to run Python scripts without problem but I can't use mentioned features. How can I fix it?
