我是比较新的这一切,我开始在这里做图像分析教程: http://www.pythonvision.org/basic-tutorial我已经安装了所有的模块,但我打一个之前没有走得很远障碍。 尝试执行时pylab.imshow(dna)
步骤,它返回下列错误:
In [10]: pylab.imshow(dna)
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-10-fc86cadb4e46> in <module>()

2375 ax.hold(hold)
2376 try:

--> 411 raise TypeError("Invalid dimensions for image data")
412
413 self._imcache =None
TypeError: Invalid dimensions for image data
相当肯定我按照教程,以信的所有指示,但我不能工作了是哪里出问题了
谢谢
