在IPython中使用enthought.mayavi正常,但在Spyder中确有问题,提示如下:
ValueError: API ‘QString‘ has already been set to version 1
问题出在import这里,
from enthought.mayavi import mlab
因为Enthought在调用PyQt时使用的是API #2,而Spyder默认使用API #1,把他改为API #2即可。
打开Tools -> Preferences,左边选择Console,右边打开External modules选项卡,在下面找到PyQt,把里面的API selection for QString and QVariant object:改为API #2,确定,再次运行时就正常了。
