I managed to configure remote interpreter. I'm not sure if my issue was exactly the same as yours because of different exception at the beginning ( java.io.IOException: inputstream is closed) but maybe it will bring you somehow closer to the solution.

It started working for me after installing openssh-sftp-server using instructions from here.

In short:

Connect using ssh with your omega Download and install openssh-sftp-server :wget https://downloads.lede-project.org/releases/packages-17.01/mipsel_24kc/packages/openssh-sftp-server_7.4p1-1_mipsel_24kc.ipk opkg install openssh-sftp-server_7.4p1-1_mipsel_24kc.ipk rm openssh-sftp-server_7.4p1-1_mipsel_24kc.ipk Configure remote interpreter as you showed on the screenshots (be sure that python interpreter path is correct)
