安装对象检测API时出错：ImportError：无法导入名称'Cycler'

Question

[好吧，这让我发疯了，我试图设置tensorflow对象检测api，我已经完成了github页面上提到的所有步骤。但是，在最后一步，当我们需要通过运行以下命令检查安装时：

python object_detection/builders/model_builder_test.py
显示此错误：

cycler已经安装，但是以某种方式无法导入。有人可以帮忙吗？ 

谢谢！

因此问题已解决。我正在使用Anaconda，并创建了一个单独的虚拟环境。问题是我必须扩展我的python路径。我只是导出了站点程序包的路径，并将其放入bashrc中，所有这些都已修复。
