Matplotlib ImportError

[snippsat]

Now, if I use Thonny matplotlib is working . Instead in VS is not working.

Thonny comes with python.

Easy to get started. Thonny comes with Python 3.7 built in

Today, I installed Visual Studio Community

It would have been better to install VS Code
Look at VS Code from start
In VS Code you can point to the Python 3.7 interpreter in Thonny,then VS Code will use that version and matplotlib will work.

Can also install Python 3.6/3.7 and pip installation under Windows.
The have that as Windows main version in Path(work from anywhere in cmd or better cmder).
Then in look like this.

C:\Users\Tom
λ python -V
Python 3.7.3

C:\Users\Tom
λ pip -V
pip 19.1.1 from c:\python37\lib\site-packages\pip (python 3.7)

# Now matplotlib will be install to version pip point to over
C:\Users\Tom
λ pip install matplotlib --upgrade
Collecting matplotlib
  Downloading ........
Successfully installed matplotlib-3.1.0

In VS Code is easy to switch interpreter look at tutorial,so now should matplotlib work in both version.
