matplotlib、conda和cycler

我刚刚安装了带有Python3 64位的Anaconda 4.3.23。我创建了虚拟环境并安装了

conda安装matplotlib

。当我执行import matplotlib.pyplot as plt时返回以下错误：

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

      3 import tensorflow as tf

    126                                 cycler)

     36 # Don't let the original cycler collide with our validating cycler

     38 
     39 # interactive_bk = ['gtk', 'gtkagg', 'gtkcairo', 'qt4agg',

ImportError: No module named 'cycler'

我在新创建的虚拟环境

tensorflow

下运行了上述所有操作。有什么想法吗？

我也有同样的问题

conda安装-c anaconda cycler

为我工作。@VincentLous谢谢，你知道

-c anadonda

的确切功能吗？我没有任何线索

-c anaconda

指定anaconda搜索包的频道（从名称到url的映射）。我不清楚频道URL的实际映射位置，但我认为，

anaconda

引用了您可以找到的包。
