I am facing a Kernel Error in Jupyter Notebook.

I am on Windows 10, created a new environment in Anaconda using Python 3.5 this morning and installed these libraries:  
Zipline 1.3.0  
nb\_conda 2.2.1  
nb\_conda\_kernels 2.1.0  
pandas 0.18.1

Initially, Jupyter Notebook did not start. I was told to downgrade “tornado” to 4.5.3.

After downgrading tornado to 4.5.3 (current version), Jupyter Notebook starts but i have the following Kernel error.

Any kind souls can help to advise on the issue. Thank you in advance.

Failed to start the kernel  
Unknown server error

It shows that you need install `win32api`.  
Are you have `win32api` in your env?

</div>

There was an issue where the `jupyter_client` anaconda package forgot to declare the new dependency on the package containing `win32api`. The latest version should have solved this, so please update the install of `jupyter_client` to fix this!

thanks all. My version of Jupyter notebook was 5.3.3. Tornado to 4.5.3 (downgraded due to some compatibility issues)

Kernel error was resolved by downgrading Jupyter notebook to 5.3.1.

Thank you all for your help.

Out of curiosity, how do i check if i have win32api in my environment? I tried searching on Google but could not make sense of what to do.

step 2 command :- “conda activate (location of your env folder)”  
step 3 command: - “python -m ipykernel install --user”

works
