google colaboratory中的Python底图

Question

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>()

--> 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.

Answer 1

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
