I have a remote interpreter set up in PyCharm.
Everytime I close and reopen PyCharm, the connection seems to be broken, and the process to "reopen" the connection doesn't feel efficient to me.
Before doing the following, it is not possible to run any script.
Here is what I usually do:

File -­> Settings
Project -> Project Interpreter
Click on the gear icon on the right.
Choose "More"
With my remote interpreter selected, click on "Edit"
Change "SSH Credentials" for "Deployment Configuration" (all the info is already filled)
Click "ok" multiple times to close everything up.

At that point, I can run any scripts on the remote machine.
What is the best/fastest way to do this? (any way to "save the settings"?)
i meet the same error, file->settings checking your interpreter setting, 
You don't set the 'host' and 'post',or your set but the content was clear. check again, and it truly work
