ContextualVersionConflict：在 Google Colab 中导入流光时出错

Question

即使在执行 reset runtime 之后，我也会收到此错误。这个过程对我不起作用。建议另一种方式。

ContextualVersionConflict: (ipykernel 4.10.1 (/usr/local/lib/python3.7/dist-packages), Requirement.parse('ipykernel>=5.1.2; python_version >= "3.4"'), {'pydeck'})

Answer 1

说明ipykernel版本与streamlit要求的版本不匹配。

使用这个

!pip install ipykernel>=5.1.2
!pip install pydeck

使用上述代码后，点击Runtime，然后点击Restart Runtime。
