【问题描述】：
当我尝试从 mayavi 导入 mlab 并从 spyder 运行脚本时，出现 UnicodeDecodeError。
我正在运行一台 Windows 8 机器。当我搜索此问题时，我发现路径或文件名中不应包含非 ASCII 字符，但在我的示例文件 test.py 中并非如此，对于这个最小示例，该文件存储在 c:\test\
from mayavi import mlab
我在控制台中得到以下输出（不管我使用 Python 还是 IPython 控制台）：
runfile('C:/test/test.py', wdir=r'C:/test')
Traceback (most recent call last):
