google colaboratory中的Python底图

Question

我曾经使用以下命令在google colaboratory中安装libgeos和底图，直到上周它才能完美运行。

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

错误显示

---------------------------------------------------------------------------
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>()
150 
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'

有没有人知道如何解决它？谢谢。

它似乎与最新的pyproj版本（2.0.1）有关，该版本于10.03.2019发布。尝试安装较旧版本的pyproj，例如。 pip install pyproj==1.9.6
