老铁们瞅一眼,看看是不是这个错
>>> from mpl_toolkits.basemap import Basemap
Traceback (most recent call last):

我在matplotlib
的github瞅了瞅,没细看,找到了这个:
一部分人说是你conda的用法不对,另一部分人说是环境变量的问题,我没管那么多,能用就行,每次运行:
from mpl_toolkits.basemap import Basemap
之前
先运行
import os
import conda
conda_file_dir = conda.__file__
conda_dir = conda_file_dir.split('lib')[0]
proj_lib = os.path.join(os.path.join(conda_dir, 'share'), 'proj')
os.environ["PROJ_LIB"] = proj_lib
from mpl_toolkits.basemap import Basemap
不过照这段代码看,他就是添加了个环境变量,倒是可以试着直接改环境变量,我没管…以后有缘的话再改吧…论文狗先滚了…
