Chialisp environment set up

I'm following along with this video:
https://www.youtube.com/watch?v=y8Thrrw25rQ&list=PLmnzWPUjpmaGzFNq2PeMljHNrXGwj2TDY&index=1
trying to set up my dev environment for chialisp.
Installed python, created virtual environment, ran pip install chia-dev-tools (got this working after installing c++ buildtools). All looks to work fine but when i run the chia --help command I'm getting errors

Any thoughts on where I might be going wrong??

For future reference I had to run this command

I don't know what i have to do. Please help!

There might be 2 situation
You are using older version of python or something messed up so try reinstalling newer version of python
conda missing some dependencies.
conda upgrade spyder

sip.setapi('QString', 2)
ValueError: API 'QString' has already been set to version 1
anyone knows how to fix it?
Edit: If it will help, I see think that the problem is explained in the last column:
ValueError: API 'QString' has already been set to version 1
Edit: I tried changing API selection for QString and QVariant objects to Api #1,#2. didn't help.
Tried either to set the "Ignore API change errors" to true, didn't help.
Tried EST_TOOLKIT from 'qt4' to 'wx'.

It might be because spider itself uses the QT library and has already initialized it.
According to this http://pythonhosted.org/spyder/installation.html you could use PySide instead of PyQt4 (but i don't know if that's a configuation option or a fallback).

Importing a resource file

I'm having trouble removing a resource file in a pyqt document, I'm also using monkeystudio IDE. I madea program with images and all linked to a resource file called "resources.qyc" and now I get the error
Traceback (most recent call last):
File "main.py", line 9, in <module>
from Login import Login
File "J:\Newone\Login.py", line 3, in <module>

exec(code_string.getvalue(), ui_globals)

ImportError: No module named resources_rc

You'll first have to compile the resource file using pyrcc4. You'll run something like this from command line:
pyrcc4 ResourceFile.qrc -o ui_ResourceFile.py
