Jupyter Notebook 单元无法运行

Question

I have opened a notebook using Anaconda, I entered the token and it opens fine. The kernel it is running is Python3. However, it is not running any cells.

I have tried checking the kernels installed, I have tried running jupyter troubleshoot in my command. My command keeps showing blocks like this:

    [I 17:36:41.918 NotebookApp] Adapting from protocol version 5.1 (kernel 543df2b4-283f-43bc-afee-c4580df2761b) to 5.3 (client).

Answer 1

The components for your Jupyter installation are out-of-date with respect to one another.

I suggest either reinstalling Anaconda from scratch or upgrading the individual packages used by the notebook.
