python - ImportError : cannot import name 'is_scalar' in Python 3. 6 虚拟环境

Question

我已经为 python 3.6 创建了一个虚拟环境。如 matplotlib/basecamp GitHub repository 中所述，我已经通过命令安装了 basemap -

pip install --user git+https://github.com/matplotlib/basemap.git

当我尝试像这样导入 basemap 时，

from mpl_toolkits.basemap import Basemap

我得到了错误

ImportError: cannot import name 'is_scalar' 

我正在使用 Ubuntu 18.04 LTS。

这在 matplotlib Basemap Github Issues 中得到了回答.

It looks like you have an older version of basemap. This has already been fixed and is in the released version v1.2.0.

Some notes: basemap is considered deprecated in favor of the cartopy package. Please learn cartopy instead. Second, the preferred method of installing basemap (or cartopy) is through conda-forge due to its complex build process and dependencies.
