@LY-must-win Thanks for opening this issue! Which browser are you using? Do you see any errors in the network tab or console in its developer tools when you load JupyterLab's launcher?

I am using the Chrome browser. I started it within the Anaconda Powershell, and this is the command window where it was launched

This is not the default kernel specification that JupyterLab ships with but most likely https://github.com/anaconda/nb_conda_kernels. It might be that there is a bug in how it defines logo. Maybe it does not handle spaces in file path?

In any case the related code does not live in JupyterLab and most kernels are known to work correctly.

To debug further you could run jupyter kernelspec list or jupyter kernelspec list --json and look up:

• whether resource_dir is correct
• whether the logo-64x64.png/logo-32x32.png/logo.svg files are in the resource dir
• how the escaping of white spaces looks like and if manually modifying the kernelspec json file helps (after restarting).

@LY-must-win
Checking back on this, if you were able to take the information that @krassowski provided and able to debug this further?

Thanks again @LY-must-win for opening this issue! I have gone ahead and created a new issue in the nb_conda_kernels repository so we can close this one out here and continue the conversation there. It would be helpful if you could provide some of the additional information that Mike mentions in his comment!
