我用anaconda安装了opencv3 of python:
conda install -c menpo opencv3=3.2.0

但当我使用它将图片转换为灰度时,如:

import cv2
import matplotlib.pyplot as plt

%matplotlib inline

image = cv2.imread('opencv_logo.png')

image1 = cv2.cvtColor(image, cv2.COLOR_RGB2GRAY)

print (image.shape)
print (image1.shape)

plt.imshow(image1)

我不知道为什么:

我用的是windows + miniconda.谁能知道为什么并帮助我？谢谢.

我想用Jupyter笔记本进行数据分析.当我按照jetbrains提供的指南进行操作时:教程:使用IPython/Jupyter Notebook和PyCharm.
1.我的工作环境是Ubunutu我已经安装了所有包:anaconda和jupyter
2.当我只测试它时:
```python

In[]: print 'hello world!'

```有一些错误:
