mayavi导入UnicodeDecodeError

Question

当我尝试从mayavi导入mlab并从spyder运行脚本时，我得到了一个UnicodeDecodeError。

我正在运行一台windows8机器。当我搜索这个问题时，我发现路径或文件名中不应该包含非ASCII码字符，但在我的示例文件test.py中并非如此，在这个最小的示例中，它存储在c:\test\

from mayavi import mlab

我在控制台中得到以下输出(使用Python还是IPython控制台无关紧要)：

runfile('C:/test/test.py', wdir=r'C:/test')

UnicodeDecodeError: 'ascii' codec can't decode byte 0xf6 in position 9: ordinal not in range(128)

Answer 1

UnicodeDecodeError：“ascii”编解码器无法解码

错误来源：

_restore_window_layo_ut中的_File "....\lib\site-packages\pyface\workbench\workbench.py"，第319行

memento = pickle.load(f)

我对它进行了如下编辑，现在它正在工作:)

memento = pickle.load(f,encoding='latin1')
