Python 尝试使用pandas测试套件pytest时出现Keyerror

大家好，这里有所有的机器学习和python专家。我寻求你的帮助

我最近看过谷歌ml速成班。他们建议在开始速成班之前先熟悉熊猫

因此，我使用PythonV3.5.2和pip中的pandas安装了PIPV8.1.1。还使用pip安装了pytest 3.5.1

但是当我尝试使用pandas文档中给出的推荐测试套件时，我遇到了错误

现在，我该如何修复它，我可能做错了什么或丢失了任何包？请帮帮我。

要在pandas中运行测试，您需要安装很多：

---

pip安装moto

？但后来出现了moto错误。首先，它在config.py文件中显示了一些keyerror。我不知道moto未安装是否是错误的主要原因。

moto

未安装是错误的主要原因。Rest只是由于未解析的导入而在

conftest

加载时崩溃。好的，让我尝试安装它。应该使用-U标志来安装moto，比如

pip install-U moto

，因为我在安装pytest时使用了U标志。经验法则：遇到问题时，始终

pip install--user

。

pip install -U [--user] ci/requirements_dev.txt
