Jupyter Notebook: Kernel Error on the Right

Question

I have just installed Anaconda and run Jupyter Notebook through command line by using jupyter notebook command. However, I am facing an issue. On the top right, I see Kernel Error. When I click on Kernel Error, I see these lines:

Traceback (most recent call last):

I can't run any Python code on Jupyter Notebook, as I am continuing to get that error.

I have gone through numerous threads on Stack Overflow for several hours. But I can't fix the issue. Please, help me to solve the issue. I am doing a course on Data Scince with Python. I can't move forward without fixing this issue.

Update 1: I have visited this Github thread and tried using the following command:

conda install -c conda-forge pywin32
conda install -c anaconda jupyter_client
conda install -c conda-forge jupyter_core
pip install --upgrade pywin32==224

However, the issue is not fixed. Instead, I am getting a new error,

ImportError: DLL load failed: The specified procedure could not be found.

This is really frustrating!

Answer 1

try this way, i fixed my jupyter.
same error site-packages\tornado

1. command

    jupyter kernelspec list

2. from the shown result

     Available kernels:  
      python3    D:\Programs\Anaconda3\share\jupyter\kernels\python3

3. open the folder, and edit kernel.json

{
    "argv": [
        "D:\\Programs\\Anaconda3\\python.exe",  //change to your correct path
        "-m",
        "ipykernel_launcher",
        "-f",
        "{connection_file}"
    ],
    "display_name": "Python 3",
    "language": "python"
}

4. restart jupyter, and it will be ok.

Answer 2

Alright. I have managed to fix the issue. I have to write these commands:

conda install -c conda-forge pywin32
conda install -c anaconda jupyter_client
conda install -c conda-forge jupyter_core
pip install --upgrade pywin32==224

Then I got an error.

import win32api pywin32
ImportError: DLL load failed: The specified procedure could not be found.

I solve the issue by writing this command that I got from this github thread:

conda install pywin32

Now, the issue has been completely fixed!

Did you try opening the anaconda navigator from terminal and then create an environment their and install the jupyter notebook in that environment and then open the jupyter notebook from the navigator
