Can't open a read only directory

I recently installed Microsoft SQL Server 2017 with Python support. In a standard installation, Python is installed in:

C:\Program Files\Microsoft SQL Server\MSSQL14.SQL_PYTHON\PYTHON_SERVICES

and the main Microsoft packages, revoscalepy and microsoftml are installed in

C:\Program Files\Microsoft SQL Server\MSSQL14.SQL_PYTHON\PYTHON_SERVICES\Lib\site-packages

I wanted to open revoscalepy in Pycharm so I navigated to the directory in the IDE and selected it.  However, it did not open, and no error messages were issued.  Note that this directory is read-only to ordinary users.  Still, I want to be able to use Pycharm to browse it and explore the modules there.  

HOw can I do that?

I'm running
