标签: python-traitlets

我在 EC2 实例上安装了 Jupyter 笔记本和实验室，由于某种原因，我收到以下错误：

ImportError：无法从“traitlets.utils”导入名称“filefind”（/usr/lib/python3/dist-packages/traitlets/utils/ init .py）

Jupyter 在浏览器中可以正常打开，但我似乎无法在 python 笔记本中工作。

我正在 Kaggle 服务器上运行 .ipynb 笔记本。

在第一个代码单元中，导入模块时，特别是来自 google.patches 的 cv2_imshow，如下所示，

from google.colab.patches import cv2_imshow

我收到此错误：

/opt/conda/lib/python3.7/site-packages/IPython/utils/traitlets.py:5: UserWarning: IPython.utils.traitlets has moved to a top-level traitlets package.
  warn("IPython.utils.traitlets has moved to a top-level traitlets package.")
