從enthought mayavi導入mlab

Question

我想從enthought mayavi模塊導入mlab。我正在使用enthought冠層分佈。

我收到以下一系列錯誤。我似乎無法找到任何類似的錯誤搜索。

有沒有人有任何想法下一步？

ImportError: cannot import name set_id_type_array 

Answer 1

看看「array_handler.py」文件。在第29行

29 from tvtk.array_ext import set_id_type_array 

沒有在文件夾中名爲「TVTK」是「array_handler.py」運行，因爲我們已經是一個叫TVTK文件夾內的文件夾。 因此，代碼應該改爲說：

from array_ext import set_id_type_array 

的「array_handler.py」在您的計算機發現

C:\...\Enthought\Canopy32\User\lib\site-packages\tvtk\array_handler.py 

我有同樣的問題，這解決了它。
