Python basemap in google colaboratory

问题

I used to use the following commands to install libgeos and basemap in google colaboratory and it worked perfectly until last week.

!apt-get -qq install libgeos-dev
!pip install -qq https://github.com/matplotlib/basemap/archive/master.zip
from mpl_toolkits.basemap import Basemap, cm

The error shows

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-3-f27b0fbc3a52> in <module>()
----> 1 from mpl_toolkits.basemap import Basemap, cm
      2 from matplotlib.patches import Polygon

/usr/local/lib/python3.6/dist-packages/mpl_toolkits/basemap/__init__.py in 
<module>()

151 # create dictionary that maps epsg codes to Basemap kwargs.
--> 152 epsgf = open(os.path.join(pyproj.pyproj_datadir,'epsg'))
153 epsg_dict={}
154 for line in epsgf:

AttributeError: module 'pyproj' has no attribute 'pyproj_datadir'

Is there anyone know how to fix it? Thanks.

It seems to have something to do with the latest pyproj release (2.0.1), which was released on 10.03.2019. Try installing older version of pyproj, eg. pip install pyproj==1.9.6
