Show Wrong Python Version

[swxu]

Issue Type: Bug
I installed python3.6.5 with homebrew on Mac, I found it shows Python3.7.1 when i was choosing a python version after i installed Python Extension, but i didn't install version 3.7. It shows two path options, /usr/local/bin/python3 and /usr/local/opt/python/bin/python3.6. Actually, they are same file.
I didn't install the newest python version, and here is the installation code:
$ brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/f2a764ef944b1080be64bd88dca9a1d80130c558/Formula/python.rb

Please provide:

1. What "python.pythonPath" is set to
2. A screenshot of the status bar showing what version is being reported
3. A screenshot of what passing -c "import sys; print(sys.version_info)" to the interpreter specified in "python.pythonPath" says when run from the terminal

Thanks a lot.
I found it shows right version today. Rebooting and killing process didn't work yesterday.
It's so weird.
"python.pythonPath": "/usr/local/bin/python3"
