Cannot load Python REPL in VS Code

[yw5aj]

Environment data

VS Code version: 1.20.1
Python Extension version: 2018.1.0
Python Version: 3.6 64 bit
OS and version: Windows 10 64 bit

Actual behavior

I installed VS Code using the default Anaconda installer (added feature on 2/17/2018). Then, I tried to load the Python REPL (control + shift + P, then Python: Start REPL). However, nothing happened; in the terminal below, it's just Windows Powershell.

Expected behavior

A Python interpreter to show up.

Steps to reproduce:

1. Install VS Code using the default Anaconda installer
2. Then, load the Python REPL (control + shift + P, then Python: Start REPL).

Logs

Please could you download the Insiders Build of the extension and test this out.
I believe this has been fixed.

Thank you for your response @DonJayamanne !

I just tried the Insiders Build and still get this:

[DonJayamanne]

Please could you try the following build of the extension?
python-2018.2.0-alpha.zip

Please rename the file extension from .zip to .vsix to install it.

Just tried! The Terminal did show something:

However, this was still present in the console. Is this relevant?

That's fine.
I'm closing this as it will be resolved with the PR #829

Opening until the PR is merged.
