enthought mayavi에서 mlab 가져 오기

Question

enthought mayavi 모듈에서 mlab을 가져 오려고합니다. 나는 enthought 캐노피 배포판을 사용하고 있습니다.

다음 일련의 오류가 발생합니다. 검색 할 때 비슷한 오류가없는 것 같습니다.

누구나 다음 단계에 대한 아이디어가 있습니까?

Answer 1

"array_handler.py"파일을 살펴보십시오. 29 행

29 from tvtk.array_ext import set_id_type_array 

에서 우리는 tvtk라는 폴더 안에 이미으로, 실행 "array_handler.py"한 폴더에 "tvtk"라고 아무 폴더가 없습니다. 그래서 코드 대신 말을해야 :

from array_ext import set_id_type_array 

은 "array_handler.py"

내가 같은 문제가 있었다

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

에서 컴퓨터에서 발견되는이 그것을 해결했다.
