笔记本中构造函数参数应为str类型

【以下的问题经过翻译处理】 我有一个 Python 3 Neptune Notebook。当我尝试运行诸如

结果 = g.V().has('代码','测试').valueMap().toList()

print('结果是' + str(result))

我得到：

~/anaconda3/envs/JupyterSystemEnv/lib/python3.6/site-packages/yarl/_url.py 在新**（cls，val，编码，严格）**

156 val = urlsplit(str(val))

157 其他：

--> 158 raise TypeError("构造函数参数应该是 str")

159

160 如果没有编码：

TypeError: 构造函数参数应该是 str

这是一个新错误，这些命令在过去一年左右有效。这是我在使用 Python 3.8 而不是 3.7 调用 Neptune 时在 python 中遇到的类似错误...我可以将笔记本 Python 更改为 3.7 吗？

在过去一周左右的时间里，为了运行笔记本，我一直在使用以下命令降级我的笔记本：

%%狂欢

aws s3 cp s3://aws-neptune-notebook/graph_notebook.tar.gz /tmp/graph_notebook.tar.gz

rm -rf /tmp/图表_notebook

tar -zxvf /tmp/graph_notebook.tar.gz -C /tmp

/tmp/graph_notebook/install.sh -v="3.0.6"

运行代码。现在我无法降级笔记本，当我尝试时得到这个：

警告：跳过 NeptuneGraphNotebook，因为它未安装。
