Take a look at the "array_handler.py" file. 看一下“ array_handler.py”文件。 In line 29
在第29行
29 from tvtk.array_ext import set_id_type_array
There is no folder called "tvtk" in the folder were "array_handler.py" is running, as we are already inside a folder called tvtk. 正在运行“ array_handler.py”的文件夹中没有名为“ tvtk”的文件夹,因为我们已经在名为tvtk的文件夹中。 So the code should instead say:
因此,代码应改为:
from array_ext import set_id_type_array
The "array_handler.py" is found in your computer in 在您的计算机中找到“ array_handler.py”
C:\...\Enthought\Canopy32\User\lib\site-packages\tvtk\array_handler.py
I had the same problem and this solved it. 我有同样的问题,这解决了它。
