[python #DGC-337873]: Run MetPy on Google Colab?


Apologies on the delayed response.

Can you confirm what version of MetPy you have installed (using `pip list`)? 
You'll want to make sure you're using MetPy 0.12.2 if you have the latest 
CartoPy 0.18, which I'm guessing you do have since you just installed. You can 
upgrade metpy with:

    pip install --upgrade metpy

Hope this helps,

> !pip install metpy
> !apt-get -qq install python-cartopy python3-cartopy
> !pip uninstall -y shapely
> !pip install shapely --no-binary shapely
> After this, I copied and ran the Skew-T example from
