Operating system

Google Colab running Python 3.6.8

Cartopy version

0.17.0 (latest)

conda list

pip list

[mmc7676]

Was this ever resolved? I have the same issue then am offered to insert

!apt-get -qq install python-cartopy python3-cartopy
import cartopy

This installs the library, but the gui does not populate images.

When I try to bring in

pip install Cartopy==0.17.0

in a regular Jupyter Notebook, this is the error

ERROR: setup.py:171: UserWarning: Unable to determine GEOS version. Ensure you have 3.3.3 or later installed, or installation may fail.
'.'.join(str(v) for v in GEOS_MIN_VERSION), ))
Proj 4.9.0 must be installed

Thanks

I'm not sure what the listed dependencies are for python3-cartopy. What that error message indicates is that it's not finding Proj.4, so you need to install the system package for that, which may solve it. You might also check the Proj Installation Guide.

To install in Colab on Ubuntu using pip, you need to install the library dependencies:

!apt-get install -qq libgdal-dev libproj-dev

Then !pip install cartopy works.
