Jupyter 在导入 matplotlib 时出现导入错误答案

【问题描述】：

我刚刚尝试集成到 Jupyter，并且我已经使用 Anaconda 很长时间了。

尝试在 IPython Notebook 中导入 matplotlib 时，

import matplotlib.pyplot as plt
%matplotlib inline

我收到此错误：

ImportError                               Traceback (most recent call last)
<ipython-input-2-385145dcc870> in <module>()
----> 1 import matplotlib.pyplot as plt
      2 get_ipython().magic(u'matplotlib inline')

ImportError: No module named matplotlib.pyplot

【问题讨论】：

rm -rf ~/Library/Enthought/
因为移除 Canopy Application 不会移除主目录中的文件夹。 support.enthought.com/entries/…
我当时删除了它。现在再次尝试 matplotlib 时，我得到了这个——在编辑中。

【解决方案1】：

我遇到了同样的问题。然后我使用以下命令将 matplotlib 库安装到我的虚拟环境中。

pip install matplotlib

然后我可以将 matplotlib 导入到 jupyter notebook。

【解决方案2】：

如果使用 conda 然后在终端类型中，我认为您应该安装 matplotlib 库：

# create a new environment with the required packages
conda create -n "matplotlib_build" python=3.5 numpy python-dateutil pyparsing pytz tornado cycler tk libpng zlib freetype
activate matplotlib_build
# if you want a qt backend, you also have to install pyqt (be aware that pyqt doesn't mix well if
# you have created the environment with conda-forge already activated...)
conda install pyqt
# this package is only available in the conda-forge channel
conda install -c conda-forge msinttypes

# copy the libs which have "wrong" names
set LIBRARY_LIB=%CONDA_PREFIX%\Library\lib
mkdir lib || cmd /c "exit /b 0"
copy %LIBRARY_LIB%\zlibstatic.lib lib\z.lib
copy %LIBRARY_LIB%\libpng_static.lib lib\png.lib

# Make the header files and the rest of the static libs available during the build
# CONDA_DEFAULT_ENV is a env variable which is set to the currently active environment path
set MPLBASEDIRLIST=%CONDA_PREFIX%\Library\;.

# build the wheel
python setup.py bdist_wheel

此代码取自 https://matplotlib.org/users/installing.html#conda-packages。希望这会有所帮助。

谢谢
