[BikashElangbam]

Hi, I am new to Jupyter Notebook, I tried to launch Jupyter Notebook from Anaconda Navigator. But , I get Kernel Error. Please advise how to fix the below issue

Can you provide more info, like the python version being used and the OS?

[BikashElangbam]

I am using Windows 10 with Python 3.8.1

[KingDarBoja]

@BikashElangbam Please take a look at #5047.

That should fix your issue in the meantime.

[Rakeshkumarvemula]

@BikashElangbam getting same error.If you resolved the issue can you help me with the error.

[BikashElangbam]

Still getting the same issue. Not sure how to fix this issue

[kevin-bates]

You're currently using slightly outdated modules (jupyter_client and jupyter_core) in which some changes have been made since the secure_write() method was introduced. I recommend you do the following:

1. Upgrade jupyter_client (e.g., pip install --upgrade jupyter_client or equivalent).
   This should update jupyter_client to 5.3.4 and jupyter_core to 4.6.1.
2. Restart your Notebook server (just the application, not the physical machine).
3. Reattempt kernel startup.

Should the kernel's start attempt still fail, please capture the traceback information in the Notebook server's console (or redirected file) as it will provide additional information pertinent to this issue.

If the kernel is successfully started, please close this issue.

Thank you and we apologize for the inconvenience.
