Hi all, When starting jupyter lab this is what appears in git bash:

Question 1

• Is there a way to get rid of this? I have windows 11.

  Question 2

• I wanted to use jupyter lab and other extensions, I have never install packages in base env. However I did install jupyter lab in (base) env as well as all other extensions (base) conda install -c conda-forge jupyterlab-drawio and (base) conda install -c conda-forge jupyterlab-execute-time. Is this correct? so then when I start jupyter lab from my (base) env those extensions are available in any project env?

  Question 3

• I also found one way to solve the above is to downgrade nbconvert by doing: conda install nbconvert=5.6.1 since I am using version 6. Nonetheless, again, is this package installed in base env?

Thanks for helping out. I've done my research to find out the best way to install all those packages but I couldn't find in what env to install it. Also, apologies if this is not the right channel to post this 🙏

for the problem of “template_path ”, you can see this issue #1529 ;)
