【问题描述】:
我的系统是 Ubuntu 15.04 64bit。 我的python版本:
**:~$ python
Python 2.7.11 |Anaconda custom (64-bit)| (default, Dec 6 2015, 18:08:32)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2
我的 ipython 版本:
**:~$ ipython
Python 2.7.11 |Anaconda custom (64-bit)| (default, Dec 6 2015, 18:08:32)
Type "copyright", "credits" or "license" for more information.
IPython 4.2.0 -- An enhanced Interactive Python.
我使用过conda install matplotlib、conda install numpy 和conda install scipy。
版本和位置
# packages in environment at /home/hust/anaconda2:
numpy 1.10.4 py27_1
matplotlib 1.5.1 np110py27_0
scipy 0.17.0 np110py27_3
在 ipython 中,
In[1] %matplotlib
Using matplotlib backend: Qt4Agg
In[2] from pylab import*
没关系。
为了在 jupyter notebook 中新建一个 python2,我使用了在 Kernels for Python 2 中找到的这些命令
conda create -n ipykernel_py2 python=2 ipykernel
source activate ipykernel_py2
python -m ipykernel install --user
现在在终端中输入jupyter notebook,然后新建一个python2。我尝试使用%matplotlib
In[1]: %matplotlib

结果是错误的。
我确实在 conda 环境中安装了 matplotlib、scipy 和 numpy。它似乎在 ipython 中运行良好,但在 jupyter notebook 中却不行。是什么原因?如果您能帮我解决这个问题,我将不胜感激。
【问题讨论】:
-
笔记本正在您设置的
ipykernel_py2环境中运行代码。您需要在该环境中安装 matplotlib。 -
哦,再次感谢您。现在通过使用pyenv,一切顺利。
